Adding Docker (#151)

Releases will now push a docker image. This is a really easy way to get
up and running:

    docker run -it elliotchance/vsql:latest cli mydb.vsql

 Installing & Updating
 =====================
 
-vsql can be installed or updated using `V <https://vlang.io>`_:
+There are lots of ways to install vsql depending on how you want to use it.
+
+Docker
+------
+
+Docker is the easiest way to get up and running (if you have
+`Docker installed <https://docs.docker.com/get-docker/>`_.). Pull the latest
+stable version with:
+
+.. code-block:: sh
+
+   docker pull elliotchance/vsql:latest
+
+You can also use major (``0``), minor (``0.27``) or patch versions (``0.27.1``).
+View all versions on
+`hub.docker.com/repository/docker/elliotchance/vsql/tags <https://hub.docker.com/repository/docker/elliotchance/vsql/tags?page=1&ordering=last_updated>`_.
+
+Run the CLI directly (see :doc:`cli`):
+
+.. code-block:: sh
+
+   docker run -it elliotchance/vsql:latest cli mydb.vsql
+
+Or, start the PostgreSQL-compatible server (see :doc:`server`):
+
+.. code-block:: sh
+
+   docker run -it elliotchance/vsql:latest server mydb.vsql
+
+Prebuilt Binaries
+-----------------
+
+This is the best way to use vsql on most platforms without any dependencies.
+
+Prebuilt binaries for macOS, Windows and Linux are available on the
+`GitHub Releases Page <https://github.com/elliotchance/vsql/releases>`_.
+
+V Package Manager
+-----------------
+
+This is the best method if you intend to build V applications using it as a
+library. See `v-client-library`.
 
 .. code-block:: sh
 
    v install elliotchance.vsql
 
-Or, if you don't have V installed you can also download standalone binaries from
-the `Releases <https://github.com/elliotchance/vsql/releases>`_.
+Compiling From Source
+---------------------
 
-See Also
---------
+This is the best choice if you want to modify vsql source or contribute to the
+project. See :doc:`contributing`:
+
+.. code-block:: sh
 
-- :doc:`cli`
-- :doc:`contributing`
-- :doc:`v-client-library`
+   git clone https://github.com/elliotchance/vsql.git
+   cd vsql
+   make bin/vsql
