Mostly added documentation, but some minor changes.

+## Prerequisites
+
+You will need [Leiningen](https://github.com/technomancy/leiningen) 2.0 or above installed.
+
+You will need [node](https://nodejs.org/en/) and [bower](https://bower.io/) installed.
+
+## Running
+
+To start a web server for the application, run:
+
+    lein bower install
+    lein ring server
+
+Alternatively, if you want to deploy to a servlet container (which I would strongly recommend), the simplest thing is to run:
+
+    lein bower install
+    lein ring uberwar
+
+(a command which I'm sure Smeagol would entirely appreciate) and deploy the resulting war file.
+
+## Experimental Docker image
+
+You can now run Smeagol as a [Docker](http://www.docker.com) image. Read more about [[Using the Docker Image]].
+
+To run my Docker image, use
+
+    docker run simonbrooke/smeagol
+
+Smeagol will run, obviously, on the IP address of your Docker image, on port 8080. To find the IP address, start the image using the command above and then use
+
+    docker inspect --format '{{ .NetworkSettings.IPAddress }}' $(docker ps -q)
+
+Suppose this prints '10.10.10.10', then the URL to browse to will be http://10.10.10.10:8080/smeagol/
+
+This image is _experimental_, but it does seem to work fairly well. What it does **not** yet do, however, is push the git repository to a remote location, so when you tear the Docker image down your edits will be lost. My next objective for this image is for it to have a cammand line parameter being the git address of a repository from which it can initialise the Wiki content, and to which it will periodically push local changes to the Wiki content.
+
+To build your own Docker image, run:
+
+    lein clean
+    lein bower install
+    lein ring uberwar
+    lein docker build
+
+This will build a new Docker image locally; you can, obviously, push it to your own Docker repository if you wish.
