 ShareLaTeX Docker Image
 =======================
 
-*THIS IS A WORK IN PROGRESS AND THESE INSTRUCTIONS DO NOT WORK YET!*
+**Please read this entire file before installing ShareLaTeX via Docker. It's only
+short but contains some important information.**
 
 The recommended way to install and run ShareLaTeX Community Edition is via Docker:
 
 ```
-$ docker run -d -v /sharelatex-data:/var/lib/sharelatex --net=host --name=sharelatex sharelatex/sharelatex
+$ docker run -d -v sharelatex:/var/lib/sharelatex --name=sharelatex sharelatex/sharelatex
 ```
 
 This will download the ShareLaTeX image and start it running in the background.
 
-**Which port does it listen on?**.
+To stop ShareLaTeX:
+
+```
+docker stop sharelatex
+```
+
+and to start it again:
+
+```
+docker start sharelatex
+```
+
+If you want to permanently remove ShareLaTeX from your docker containers:
+
+```
+docker rm sharelatex
+```
+
+### Storing Data
+
+The `-v sharelatex:/var/lib/sharelatex` option in the `run` command tells 
+Docker to make the host directory `sharelatex` available inside the container for 
+ShareLaTeX to store data files in. This means that you can back up and access these
+files manually outside of the ShareLaTeX container. If you would like to store ShareLaTeX data
+in a different location, such as `/home/james/my_data`, just change this parameter:
+
+```
+$ docker run -d \
+  -v /home/james/my_data:/var/lib/sharelatex \
+  --name=sharelatex \
+  sharelatex/sharelatex
+```
+
+Do not change the second part of this parameter (after the :).
+
+This is only where ShareLaTeX stores on-disk data.
+Other data is also stored in Mongo and Redis.
 
 ### Mongo and Redis
 
-The `--net=host` option to docker will allow the ShareLaTeX container to access
-ports on the local system. By default it looks for an instance of
-[MongoDB](http://www.mongodb.org/) (must be version 2.4 or later) running on port 27017, and
-[Redis](http://redis.io/) (must be version 2.6.12 or later) running on port 6379. These are the default ports for
-a standard installation of MongoDB and Redis.
+ShareLaTeX depends on [MongoDB](http://www.mongodb.org/) (must be 2.4 or later), and
+[Redis](http://redis.io/) (must be version 2.6.12 or later).
+These should be running on the host system.
+
+By default the ShareLaTeX Docker container looks for these running on the host
+machine at port 27017 (for Mongo) and port 6379 (for Redis). These are the defaults
+ports for both databases so you shouldn't need to change them.
 
-### Persisting and backing up data
+If you want to point ShareLaTeX at a database in a different location, you can
+configure the container with environment variables. See the **Configuration Options**
+section below.
 
-The `-v /sharelatex-data:/var/lib/sharelatex` option in the `run` command tells Docker to mount the local
-directory `/sharelatex-data` in the container at `/var/lib/sharelatex`. This is
-where ShareLaTeX will store user uploaded files, and allows you to make external backups
-of these files, as well as persist them between updates to the ShareLaTeX image.
+*Note that `localhost` in the container refers only to the container, so if you
+want to access services on the host machine then you should use `dockerhost`.* For example:
+
+```
+$ docker run -d \
+  -v sharelatex:/var/lib/sharelatex \
+  --name=sharelatex \
+  --env SHARELATEX_MONGO_URL=mongodb://dockerhost/sharelatex \
+  sharelatex/sharelatex
+```
+
+### Backups
+
+To backup the ShareLaTeX data, you need to backup the directory you have attached
+to the container, as above. You also need to backup the Mongo and Redis databases.
+
+### Running on a different port
+
+The container listens on port 80 by default so you should be able to access
+ShareLaTeX at http://localhost/. If you would like to run ShareLaTeX on a different
+port (perhaps you have another service running on port 80, or want to put a proxy
+in front of ShareLaTeX), then you can forward port 80 from the Docker container
+to any other port with the `-p <PORT>:80` option. For example, to have ShareLaTeX
+listen on port 5000:
+
+```
+$ docker run -d \
+  -v sharelatex:/var/lib/sharelatex \
+  --name=sharelatex \
+  -p 5000:80 \
+  --env SHARELATEX_SITE_URL=http://localhost:5000 \
+  sharelatex/sharelatex
+```
+
+(Note that you also have to update the `SHARELATEX_SITE_URL` parameter so that
+it knows where it is publicly available.)
