 ## Stop yacking and tell me how to generate the database from the YAMl!
 
-Ok!
+Ok! There are two ways of doing this; using Docker containers, and manually
+setting things up. If you just want to generate the database and use it, I'd
+recommend Docker, if you want to actively develop this repo the manual setup
+may be preferable.
+
+### Using Docker
+
+First you will need docker, you can set that up from [here](https://www.docker.com/get-started).
+
+The included Dockerfile is set up so that it will install the correct
+dependencies and run the database generation script. This will get you a
+generated database, and copy it into your working directory:
+
+```
+docker build -t pathfinder-2-sqlite -f .\Dockerfile .
+docker run --name pathfinder-2-sqlite-container -t pathfinder-2-sqlite
+docker cp pathfinder-2-sqlite-container:/project/tmp.db .
+docker container rm pathfinder-2-sqlite-container
+```
+
+### Manual Setup
 
 You'll need a working python3 installation and the module `pyyaml` installed.
