+# Docker
+
+There is a `docker-compose.yaml` file to help you spin up an instance quickly.
+
+## Prerequisites:
+
+### Docker
+
+You will need [Docker](https://docs.docker.com/get-docker/) and [Docker Compose](https://docs.docker.com/compose/install/). Follow the instructions for your distro.
+
+### Directories
+
+You will need to create a directory for the `postgres` data:
+
+```sh
+mkdir -p postgres
+```
+
+**Note:** This directory will get owned by 'postgres' user when postgres first starts up!
+
+## Quickstart
+
+```sh
+docker-compose up -d && docker-compose logs -f
+```
+
+You can CTRL+C to stop tailing logs. If you want to stop the processes then running `docker-compose down` will shut everything down.
+
+**Note:** The first time you bring up the containers can take a minute or so - Docker has to pull/build images, grab node dependencies, apply database migrations etc. Subsequent runs will be significantly faster to spin up.
+
+### Re-building Images
+
+If the Docker images become stale (e.g. updates are made to `requirements.txt`), then you can run the following to build the images before they are spin up:
+
+```sh
+docker-compose up -d --build
+```
