+# Contributing to Fig
+
+## Development environment
+
+If you're looking contribute to [Fig](http://orchardup.github.io/fig/)
+but you're new to the project or maybe even to Python, here are the steps
+that should get you started.
+
+1. Fork [https://github.com/orchardup/fig](https://github.com/orchardup/fig) to your username. kvz in this example.
+1. Clone your forked repository locally `git clone git@github.com:kvz/fig.git`.
+1. Enter the local directory `cd fig`.
+1. Set up a development environment `python setup.py develop`. That will install the dependencies and set up a symlink from your `fig` executable to the checkout of the repo. So from any of your fig projects, `fig` now refers to your development project. Time to start hacking : )
+1. Works for you? Run the test suite via `./scripts/test` to verify it won't break other usecases.
+1. All good? Commit and push to GitHub, and submit a pull request.
+
+## Running the test suite
+
+    $ script/test
+
+## Building binaries
+
+Linux:
+
+    $ script/build-linux
+
+OS X:
+
+    $ script/build-osx
+
+Note that this only works on Mountain Lion, not Mavericks, due to a [bug in PyInstaller](http://www.pyinstaller.org/ticket/807).
+
+## Sign your work
+
+The sign-off is a simple line at the end of the explanation for the
+patch, which certifies that you wrote it or otherwise have the right to
+pass it on as an open-source patch.  The rules are pretty simple: if you
+can certify the below (from [developercertificate.org](http://developercertificate.org/)):
+
+    Developer's Certificate of Origin 1.1
+
+    By making a contribution to this project, I certify that:
+
+    (a) The contribution was created in whole or in part by me and I
+        have the right to submit it under the open source license
+        indicated in the file; or
+
+    (b) The contribution is based upon previous work that, to the best
+        of my knowledge, is covered under an appropriate open source
+        license and I have the right under that license to submit that
+        work with modifications, whether created in whole or in part
+        by me, under the same open source license (unless I am
+        permitted to submit under a different license), as indicated
+        in the file; or
+
+    (c) The contribution was provided directly to me by some other
+        person who certified (a), (b) or (c) and I have not modified
+        it.
+
+    (d) I understand and agree that this project and the contribution
+        are public and that a record of the contribution (including all
+        personal information I submit with it, including my sign-off) is
+        maintained indefinitely and may be redistributed consistent with
+        this project or the open source license(s) involved.
+
+then you just add a line saying
+
+    Signed-off-by: Random J Developer <random@developer.example.org>
+
+using your real name (sorry, no pseudonyms or anonymous contributions.)
+
+The easiest way to do this is to use the `--signoff` flag when committing. E.g.:
+
+
+    $ git commit --signoff
+

+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason

 Fig
-====
+===
 
-Punctual, lightweight development environments using Docker.
+[![Build Status](https://travis-ci.org/orchardup/fig.svg?branch=master)](https://travis-ci.org/orchardup/fig)
+[![PyPI version](https://badge.fury.io/py/fig.png)](http://badge.fury.io/py/fig)
 
-Fig is tool for defining and running isolated application environments. It uses simple, version-controllable YAML configuration files that look something like this:
+Fast, isolated development environments using Docker.
 
-```yaml
-web:
-  build: .
-  links:
-   - db
-  ports:
-   - 8000:8000
-db:
-  image: orchardup/postgresql
-```
+Define your app's environment with Docker so it can be reproduced anywhere:
 
-Installing
-----------
-
-```bash
-$ sudo pip install fig
-```
-
-Defining your app
------------------
-
-Put a `fig.yml` in your app's directory. Each top-level key defines a "service", such as a web app, database or cache. For each service, Fig will start a Docker container, so at minimum it needs to know what image to use.
-
-The simplest way to get started is to just give it an image name:
-
-```yaml
-db:
-  image: orchardup/postgresql
-```
-
-You've now given Fig the minimal amount of configuration it needs to run:
-
-```bash
-$ fig up
-Pulling image orchardup/postgresql...
-Starting myapp_db_1...
-myapp_db_1 is running at 127.0.0.1:45678
-<...output from postgresql server...>
-```
-
-For each service you've defined, Fig will start a Docker container with the specified image, building or pulling it if necessary. You now have a PostgreSQL server running at `127.0.0.1:45678`.
-
-By default, `fig up` will run until each container has shut down, and relay their output to the terminal. To run in the background instead, pass the `-d` flag:
-
-```bash
-$ fig up -d
-Starting myapp_db_1... done
-myapp_db_1 is running at 127.0.0.1:45678
-
-$ fig ps
-Name         State  Ports
-------------------------------------
-myapp_db_1   Up     5432->45678/tcp
-```
-
-### Building services
-
-Fig can automatically build images for you if your service specifies a directory with a `Dockerfile` in it (or a Git URL, as per the `docker build` command).
-
-This example will build an image with `app.py` inside it:
-
-#### app.py
-
-```python
-print "Hello world!"
-```
-
-#### fig.yml
-
-```yaml
-web:
-  build: .
-```
-
-#### Dockerfile
-
-    FROM ubuntu:12.04
-    RUN apt-get install python
-    ADD . /opt
-    WORKDIR /opt
+    FROM orchardup/python:2.7
+    ADD . /code
+    WORKDIR /code
+    RUN pip install -r requirements.txt
     CMD python app.py
 
-
-
-### Getting your code in
-
-If you want to work on an application being run by Fig, you probably don't want to have to rebuild your image every time you make a change. To solve this, you can share the directory with the container using a volume so the changes are reflected immediately:
+Define the services that make up your app so they can be run together in an isolated environment:
 
 ```yaml
-web:
-  build: .
-  volumes:
-   - .:/opt
-```
-
-
-### Communicating between containers
-
-Your web app will probably need to talk to your database. You can use [Docker links](http://docs.docker.io/en/latest/use/port_redirection/#linking-a-container) to enable containers to communicate, pass in the right IP address and port via environment variables:
-
-```yaml
-db:
-  image: orchardup/postgresql
-
 web:
   build: .
   links:
    - db
-```
-
-This will pass an environment variable called `MYAPP_DB_1_PORT` into the web container, whose value will look like `tcp://172.17.0.4:45678`. Your web app's code can use that to connect to the database. To see all of the environment variables available, run `env` inside a container:
-
-```bash
-$ fig up -d db
-$ fig run web env
-```
-
-
-### Container configuration options
-
-You can pass extra configuration options to a container, much like with `docker run`:
-
-```yaml
-web:
-  build: .
-
-  -- override the default command
-  command: bundle exec thin -p 3000
-
-  -- expose ports, optionally specifying both host and container ports (a random host port will be chosen otherwise)
   ports:
-   - 3000
-   - 8000:8000
-
-  -- map volumes
-  volumes:
-   - cache/:/tmp/cache
-
-  -- add environment variables
-  environment:
-   RACK_ENV: development
+   - "8000:8000"
+   - "49100:22"
+db:
+  image: orchardup/postgresql
 ```
 
+(No more installing Postgres on your laptop!)
 
-Running a one-off command
--------------------------
+Then type `fig up`, and Fig will start and run your entire app:
 
-If you want to run a management command, use `fig run` to start a one-off container:
+![example fig run](https://orchardup.com/static/images/fig-example-large.gif)
 
-```bash
-$ fig run db createdb myapp_development
-$ fig run web rake db:migrate
-$ fig run web bash
-```
+There are commands to:
 
+ - start, stop and rebuild services
+ - view the status of running services
+ - tail running services' log output
+ - run a one-off command on a service

+---
+
+CLI reference
+=============
+
+Most commands are run against one or more services. If the service is omitted, it will apply to all services.
+
+Run `fig [COMMAND] --help` for full usage.
+
+## build
+
+Build or rebuild services.
+
+Services are built once and then tagged as `project_service`, e.g. `figtest_db`. If you change a service's `Dockerfile` or the contents of its build directory, you can run `fig build` to rebuild it.
+
+## help
+
+Get help on a command.
+
+## kill
+
+Force stop service containers.
+
+## logs
+
+View output from services.
+
+## ps
+
+List containers.
+
+## rm
+
+Remove stopped service containers.
+
+
+## run
+
+Run a one-off command on a service.
+
+For example:
+
+    $ fig run web python manage.py shell
+
+Note that this will not start any services that the command's service links to. So if, for example, your one-off command talks to your database, you will need to run `fig up -d db` first.
+
+One-off commands are started in new containers with the same config as a normal container for that service, so volumes, links, etc will all be created as expected. The only thing different to a normal container is the command will be overridden with the one specified and no ports will be created in case they collide.
+
+Links are also created between one-off commands and the other containers for that service so you can do stuff like this:
+
+    $ fig run db /bin/sh -c "psql -h \$DB_1_PORT_5432_TCP_ADDR -U docker"
+
+## scale
+
+Set number of containers to run for a service.
+
+Numbers are specified in the form `service=num` as arguments.
+For example:
+
+    $ fig scale web=2 worker=3
+
+## start
+
+Start existing containers for a service.
+
+## stop
+
+Stop running containers without removing them. They can be started again with `fig start`.
+
+## up
+
+Build, (re)create, start and attach to containers for a service.
+
+By default, `fig up` will aggregate the output of each container, and when it exits, all containers will be stopped. If you run `fig up -d`, it'll start the containers in the background and leave them running.
+
+If there are existing containers for a service, `fig up` will stop and recreate them (preserving mounted volumes with [volumes-from]), so that changes in `fig.yml` are picked up.
+

+title: Getting started with Fig and Django
+---
+
+Getting started with Fig and Django
+===================================
+
+Let's use Fig to set up and run a Django/PostgreSQL app. Before starting, you'll need to have [Fig installed](install.html).
+
+Let's set up the three files that'll get us started. First, our app is going to be running inside a Docker container which contains all of its dependencies. We can define what goes inside that Docker container using a file called `Dockerfile`. It'll contain this to start with:
+
+    FROM orchardup/python:2.7
+    ENV PYTHONUNBUFFERED 1
+    RUN apt-get update -qq && apt-get install -y python-psycopg2
+    RUN mkdir /code
+    WORKDIR /code
+    ADD requirements.txt /code/
+    RUN pip install -r requirements.txt
+    ADD . /code/
+
+That'll install our application inside an image with Python installed alongside all of our Python dependencies. For more information on how to write Dockerfiles, see the [Docker user guide](https://docs.docker.com/userguide/dockerimages/#building-an-image-from-a-dockerfile) and the [Dockerfile reference](http://docs.docker.com/reference/builder/).
+
+Second, we define our Python dependencies in a file called `requirements.txt`:
+
+    Django
+
+Simple enough. Finally, this is all tied together with a file called `fig.yml`. It describes the services that our app comprises of (a web server and database), what Docker images they use, how they link together, what volumes will be mounted inside the containers and what ports they expose.
+
+    db:
+      image: orchardup/postgresql
+    web:
+      build: .
+      command: python manage.py runserver 0.0.0.0:8000
+      volumes:
+        - .:/code
+      ports:
+        - "8000:8000"
+      links:
+        - db
+
+See the [`fig.yml` reference](http://orchardup.github.io/fig/yml.html) for more information on how it works.
+
+We can now start a Django project using `fig run`:
+
+    $ fig run web django-admin.py startproject figexample .
+
+First, Fig will build an image for the `web` service using the `Dockerfile`. It will then run `django-admin.py startproject figexample .` inside a container using that image.
+
+This will generate a Django app inside the current directory:
+
+    $ ls
+    Dockerfile       fig.yml          figexample       manage.py        requirements.txt
+
+First thing we need to do is set up the database connection. Replace the `DATABASES = ...` definition in `figexample/settings.py` to read:
+
+    DATABASES = {
+        'default': {
+            'ENGINE': 'django.db.backends.postgresql_psycopg2',
+            'NAME': 'docker',
+            'USER': 'docker',
+            'PASSWORD': 'docker',
+            'HOST': os.environ.get('DB_1_PORT_5432_TCP_ADDR'),
+            'PORT': os.environ.get('DB_1_PORT_5432_TCP_PORT'),
+        }
+    }
+
+These settings are determined by the [orchardup/postgresql](https://github.com/orchardup/docker-postgresql) Docker image we are using.
+
+Then, run `fig up`:
+
+    Recreating myapp_db_1...
+    Recreating myapp_web_1...
+    Attaching to myapp_db_1, myapp_web_1
+    myapp_db_1 |
+    myapp_db_1 | PostgreSQL stand-alone backend 9.1.11
+    myapp_db_1 | 2014-01-27 12:17:03 UTC LOG:  database system is ready to accept connections
+    myapp_db_1 | 2014-01-27 12:17:03 UTC LOG:  autovacuum launcher started
+    myapp_web_1 | Validating models...
+    myapp_web_1 |
+    myapp_web_1 | 0 errors found
+    myapp_web_1 | January 27, 2014 - 12:12:40
+    myapp_web_1 | Django version 1.6.1, using settings 'figexample.settings'
+    myapp_web_1 | Starting development server at http://0.0.0.0:8000/
+    myapp_web_1 | Quit the server with CONTROL-C.
+
+And your Django app should be running at [localhost:8000](http://localhost:8000) (or [localdocker:8000](http://localdocker:8000) if you're using docker-osx).
+
+You can also run management commands with Docker. To set up your database, for example, run `fig up` and in another terminal run:
+
+    $ fig run web python manage.py syncdb

+Environment variables reference
+===============================
+
+Fig uses [Docker links] to expose services' containers to one another. Each linked container injects a set of environment variables, each of which begins with the uppercase name of the container.
+
+To see what environment variables are available to a service, run `fig run SERVICE env`.
+
+<b><i>name</i>\_PORT</b><br>

+Define your app's environment with Docker so it can be reproduced anywhere:
+
+    FROM orchardup/python:2.7
+    ADD . /code
+    WORKDIR /code
+    RUN pip install -r requirements.txt
+
+Define the services that make up your app so they can be run together in an isolated environment:
+
+```yaml
+web:
+  build: .
+  command: python app.py
+  links:
+   - db
+  ports:
+   - "8000:8000"
+db:
+  image: orchardup/postgresql
+```
+
+(No more installing Postgres on your laptop!)
+
+Then type `fig up`, and Fig will start and run your entire app:
+
+![example fig run](https://orchardup.com/static/images/fig-example-large.gif)
+
+There are commands to:
+
+ - start, stop and rebuild services
+ - view the status of running services
+ - tail running services' log output
+ - run a one-off command on a service
+
+
+Quick start
+-----------
+
+Let's get a basic Python web app running on Fig. It assumes a little knowledge of Python, but the concepts should be clear if you're not familiar with it.
+
+First, [install Docker and Fig](install.html).
+
+You'll want to make a directory for the project:
+
+    $ mkdir figtest
+    $ cd figtest
+
+Inside this directory, create `app.py`, a simple web app that uses the Flask framework and increments a value in Redis:
+
+```python
+from flask import Flask
+from redis import Redis
+import os
+app = Flask(__name__)
+redis = Redis(
+    host=os.environ.get('REDIS_1_PORT_6379_TCP_ADDR'),
+    port=int(os.environ.get('REDIS_1_PORT_6379_TCP_PORT'))
+)
+
+@app.route('/')
+def hello():
+    redis.incr('hits')
+    return 'Hello World! I have been seen %s times.' % redis.get('hits')
+
+if __name__ == "__main__":
+    app.run(host="0.0.0.0", debug=True)
+```
+
+We define our Python dependencies in a file called `requirements.txt`:
+
+    flask
+    redis
+
+Next, we want to create a Docker image containing all of our app's dependencies. We specify how to build one using a file called `Dockerfile`:
+
+    FROM orchardup/python:2.7
+    ADD . /code
+    WORKDIR /code
+    RUN pip install -r requirements.txt
+
+This tells Docker to install Python, our code and our Python dependencies inside a Docker image. For more information on how to write Dockerfiles, see the [Docker user guide](https://docs.docker.com/userguide/dockerimages/#building-an-image-from-a-dockerfile) and the [Dockerfile reference](http://docs.docker.com/reference/builder/).
+
+We then define a set of services using `fig.yml`:
+
+    web:
+      build: .
+      command: python app.py
+      ports:
+       - "5000:5000"
+      volumes:
+       - .:/code
+      links:
+       - redis
+    redis:
+      image: orchardup/redis
+
+This defines two services:
+
+ - `web`, which is built from `Dockerfile` in the current directory. It also says to run the command `python app.py` inside the image, forward the exposed port 5000 on the container to port 5000 on the host machine, connect up the Redis service, and mount the current directory inside the container so we can work on code without having to rebuild the image.
+ - `redis`, which uses the public image [orchardup/redis](https://index.docker.io/u/orchardup/redis/). 
+
+Now if we run `fig up`, it'll pull a Redis image, build an image for our own code, and start everything up:
+
+    $ fig up
+    Pulling image orchardup/redis...
+    Building web...
+    Starting figtest_redis_1...
+    Starting figtest_web_1...
+    figtest_redis_1 | [8] 02 Jan 18:43:35.576 # Server started, Redis version 2.8.3
+    figtest_web_1 |  * Running on http://0.0.0.0:5000/
+
+Open up [http://localhost:5000](http://localhost:5000) in your browser (or [http://localdocker:5000](http://localdocker:5000) if you're using [docker-osx](https://github.com/noplay/docker-osx)) and you should see it running!
+
+If you want to run your services in the background, you can pass the `-d` flag to `fig up` and use `fig ps` to see what is currently running:
+
+    $ fig up -d
+    Starting figtest_redis_1...
+    Starting figtest_web_1...
+    $ fig ps
+            Name                 Command            State       Ports
+    -------------------------------------------------------------------
+    figtest_redis_1   /usr/local/bin/run         Up
+    figtest_web_1     /bin/sh -c python app.py   Up      5000->5000/tcp
+
+`fig run` allows you to run one-off commands for your services. For example, to see what environment variables are available to the `web` service:
+
+    $ fig run web env
+
+
+See `fig --help` other commands that are available.
+
+If you started Fig with `fig up -d`, you'll probably want to stop your services once you've finished with them:
+
+    $ fig stop
+
+That's more-or-less how Fig works. See the reference section below for full details on the commands, configuration file and environment variables. If you have any thoughts or suggestions, [open an issue on GitHub](https://github.com/orchardup/fig) or [email us](mailto:hello@orchardup.com).

+
+Installing Fig
+==============
+
+First, install Docker version 1.0.0. If you're on OS X, you can use [docker-osx](https://github.com/noplay/docker-osx):
+
+    $ curl https://raw.githubusercontent.com/noplay/docker-osx/1.0.0/docker-osx > /usr/local/bin/docker-osx
+    $ chmod +x /usr/local/bin/docker-osx
+    $ docker-osx shell
+
+Docker has guides for [Ubuntu](http://docs.docker.io/en/latest/installation/ubuntulinux/) and [other platforms](http://docs.docker.io/en/latest/installation/) in their documentation.
+
+Next, install Fig. On OS X:
+
+    $ curl -L https://github.com/orchardup/fig/releases/download/0.4.2/darwin > /usr/local/bin/fig
+    $ chmod +x /usr/local/bin/fig
+
+On 64-bit Linux:
+
+    $ curl -L https://github.com/orchardup/fig/releases/download/0.4.2/linux > /usr/local/bin/fig
+    $ chmod +x /usr/local/bin/fig
+
+Fig is also available as a Python package if you're on another platform (or if you prefer that sort of thing):
+
+    $ sudo pip install -U fig
+
+That should be all you need! Run `fig --version` to see if it worked.

+
+Getting started with Fig and Rails
+==================================
+
+We're going to use Fig to set up and run a Rails/PostgreSQL app. Before starting, you'll need to have [Fig installed](install.html).
+
+Let's set up the three files that'll get us started. First, our app is going to be running inside a Docker container which contains all of its dependencies. We can define what goes inside that Docker container using a file called `Dockerfile`. It'll contain this to start with:
+
+    FROM binaryphile/ruby:2.0.0-p247
+    RUN apt-get update -qq && apt-get install -y build-essential libpq-dev
+    RUN mkdir /myapp
+    WORKDIR /myapp
+    ADD Gemfile /myapp/Gemfile
+    RUN bundle install
+    ADD . /myapp
+
+That'll put our application code inside an image with Ruby, Bundler and all our dependencies. For more information on how to write Dockerfiles, see the [Docker user guide](https://docs.docker.com/userguide/dockerimages/#building-an-image-from-a-dockerfile) and the [Dockerfile reference](http://docs.docker.com/reference/builder/).
+
+Next, we have a bootstrap `Gemfile` which just loads Rails. It'll be overwritten in a moment by `rails new`.
+
+    source 'https://rubygems.org'
+    gem 'rails', '4.0.2'
+
+Finally, `fig.yml` is where the magic happens. It describes what services our app comprises (a database and a web app), how to get each one's Docker image (the database just runs on a pre-made PostgreSQL image, and the web app is built from the current directory), and the configuration we need to link them together and expose the web app's port.
+
+    db:
+      image: orchardup/postgresql
+      ports:
+        - "5432"
+    web:
+      build: .
+      command: bundle exec rackup -p 3000
+      volumes:
+        - .:/myapp
+      ports:
+        - "3000:3000"
+      links:
+        - db
+
+With those files in place, we can now generate the Rails skeleton app using `fig run`:
+
+    $ fig run web rails new . --force --database=postgresql --skip-bundle
+
+First, Fig will build the image for the `web` service using the `Dockerfile`. Then it'll run `rails new` inside a new container, using that image. Once it's done, you should have a fresh app generated:
+
+    $ ls
+    Dockerfile   app          fig.yml      tmp
+    Gemfile      bin          lib          vendor
+    Gemfile.lock config       log
+    README.rdoc  config.ru    public
+    Rakefile     db           test
+
+Uncomment the line in your new `Gemfile` which loads `therubyracer`, so we've got a Javascript runtime:
+
+    gem 'therubyracer', platforms: :ruby
+
+Now that we've got a new `Gemfile`, we need to build the image again. (This, and changes to the Dockerfile itself, should be the only times you'll need to rebuild).
+
+    $ fig build
+
+The app is now bootable, but we're not quite there yet. By default, Rails expects a database to be running on `localhost` - we need to point it at the `db` container instead. We also need to change the username and password to align with the defaults set by `orchardup/postgresql`.
+
+Open up your newly-generated `database.yml`. Replace its contents with the following:
+
+    development: &default
+      adapter: postgresql
+      encoding: unicode
+      database: myapp_development
+      pool: 5
+      username: docker
+      password: docker
+      host: <%= ENV.fetch('DB_1_PORT_5432_TCP_ADDR', 'localhost') %>
+      port: <%= ENV.fetch('DB_1_PORT_5432_TCP_PORT', '5432') %>
+
+    test:
+      <<: *default
+      database: myapp_test
+
+We can now boot the app.
+
+    $ fig up
+
+If all's well, you should see some PostgreSQL output, and then—after a few seconds—the familiar refrain:
+
+    myapp_web_1 | [2014-01-17 17:16:29] INFO  WEBrick 1.3.1
+    myapp_web_1 | [2014-01-17 17:16:29] INFO  ruby 2.0.0 (2013-11-22) [x86_64-linux-gnu]
+    myapp_web_1 | [2014-01-17 17:16:29] INFO  WEBrick::HTTPServer#start: pid=1 port=3000
+
+Finally, we just need to create the database. In another terminal, run:
+
+    $ fig run web rake db:create
+
+And we're rolling—see for yourself at [localhost:3000](http://localhost:3000) (or [localdocker:3000](http://localdocker:3000) if you're using docker-osx).

+Getting started with Fig and Wordpress
+======================================
+
+Fig makes it nice and easy to run Wordpress in an isolated environment. [Install Fig](install.html), then download Wordpress into the current directory:
+
+    $ curl http://wordpress.org/wordpress-3.8.1.tar.gz | tar -xvzf -
+
+This will create a directory called `wordpress`, which you can rename to the name of your project if you wish. Inside that directory, we create `Dockerfile`, a file that defines what environment your app is going to run in:
+
+```
+FROM orchardup/php5
+ADD . /code
+```
+
+This instructs Docker on how to build an image that contains PHP and Wordpress. For more information on how to write Dockerfiles, see the [Docker user guide](https://docs.docker.com/userguide/dockerimages/#building-an-image-from-a-dockerfile) and the [Dockerfile reference](http://docs.docker.com/reference/builder/).
+
+Next up, `fig.yml` starts our web service and a separate MySQL instance:
+
+```
+web:
+  build: .
+  command: php -S 0.0.0.0:8000 -t /code
+  ports:
+    - "8000:8000"
+  links:
+    - db
+  volumes:
+    - .:/code
+db:
+  image: orchardup/mysql
+  environment:
+    MYSQL_DATABASE: wordpress
+```
+
+Two supporting files are needed to get this working - first up, `wp-config.php` is the standard Wordpress config file with a single change to make it read the MySQL host and port from the environment variables passed in by Fig:
+
+```
+<?php
+define('DB_NAME', 'wordpress');
+define('DB_USER', 'root');
+define('DB_PASSWORD', '');
+define('DB_HOST', getenv("DB_1_PORT_3306_TCP_ADDR") . ":" . getenv("DB_1_PORT_3306_TCP_PORT"));
+define('DB_CHARSET', 'utf8');
+define('DB_COLLATE', '');
+
+define('AUTH_KEY',         'put your unique phrase here');
+define('SECURE_AUTH_KEY',  'put your unique phrase here');
+define('LOGGED_IN_KEY',    'put your unique phrase here');
+define('NONCE_KEY',        'put your unique phrase here');
+define('AUTH_SALT',        'put your unique phrase here');
+define('SECURE_AUTH_SALT', 'put your unique phrase here');
+define('LOGGED_IN_SALT',   'put your unique phrase here');
+define('NONCE_SALT',       'put your unique phrase here');
+
+$table_prefix  = 'wp_';
+define('WPLANG', '');
+define('WP_DEBUG', false);
+
+if ( !defined('ABSPATH') )
+    define('ABSPATH', dirname(__FILE__) . '/');
+
+require_once(ABSPATH . 'wp-settings.php');
+```
+
+Finally, `router.php` tells PHP's built-in web server how to run Wordpress:
+
+```
+<?php
+
+$root = $_SERVER['DOCUMENT_ROOT'];
+chdir($root);
+$path = '/'.ltrim(parse_url($_SERVER['REQUEST_URI'])['path'],'/');
+set_include_path(get_include_path().':'.__DIR__);
+if(file_exists($root.$path))
+{
+    if(is_dir($root.$path) && substr($path,strlen($path) - 1, 1) !== '/')
+        $path = rtrim($path,'/').'/index.php';
+    if(strpos($path,'.php') === false) return false;
+    else {
+        chdir(dirname($root.$path));
+        require_once $root.$path;
+    }
+}else include_once 'index.php';
+```
+
+With those four files in place, run `fig up` inside your Wordpress directory and it'll pull and build the images we need, and then start the web and database containers. You'll then be able to visit Wordpress and set it up by visiting [localhost:8000](http://localhost:8000) - or [localdocker:8000](http://localdocker:8000) if you're using docker-osx.

+fig.yml reference
+=================
+
+Each service defined in `fig.yml` must specify exactly one of `image` or `build`. Other keys are optional, and are analogous to their `docker run` command-line counterparts.
+
+As with `docker run`, options specified in the Dockerfile (e.g. `CMD`, `EXPOSE`, `VOLUME`, `ENV`) are respected by default - you don't need to specify them again in `fig.yml`.
+
+```yaml
+-- Tag or partial image ID. Can be local or remote - Fig will attempt to pull
+-- if it doesn't exist locally.
+image: ubuntu
+image: orchardup/postgresql
+image: a4bc65fd
+
+-- Path to a directory containing a Dockerfile. Fig will build and tag it with
+-- a generated name, and use that image thereafter.
+build: /path/to/build/dir
+
+-- Override the default command.
+command: bundle exec thin -p 3000
+
+-- Link to containers in another service. Optionally specify an alternate name
+-- for the link, which will determine how environment variables are prefixed,
+-- e.g. "db" -> DB_1_PORT, "db:database" -> DATABASE_1_PORT
+links:
+ - db
+ - db:database
+ - redis
+
+-- Expose ports. Either specify both ports (HOST:CONTAINER), or just the
+-- container port (a random host port will be chosen).
+-- Note: When mapping ports in the HOST:CONTAINER format, you may experience
+-- erroneous results when using a container port lower than 60, because YAML
+-- will parse numbers in the format "xx:yy" as sexagesimal (base 60). For
+-- this reason, we recommend always explicitly specifying your port mappings
+-- as strings.
+ports:
+ - "3000"
+ - "8000:8000"
+ - "49100:22"
+
+-- Expose ports without publishing them to the host machine - they'll only be
+-- accessible to linked services. Only the internal port can be specified.
+expose:
+ - "3000"
+ - "8000"
+
+-- Map volumes from the host machine (HOST:CONTAINER).
+volumes:
+ - cache/:/tmp/cache
+
+-- Add environment variables.
