+### Running in development mode
+
+To run `Taskcafe` in development mode, you will need a postgres database running on your local computer (Docker is a good option for this).
+
+Then configure Taskcafe to connect to the development database using a `conf/taskcafe.toml` config file (an example can be found in `conf/taskcafe.example.toml`).
+
+Next open up a terminal and run the API (as well as running initial schema migrations):
+
+```
+go run cmd/taskcafe/main.go web --migrate
+```
+
+Next, start the React frontend:
+
+```
+cd frontend
+yarn start
+```
+
+Now you can access the interface through http://localhost:3000 while the API is served
+through http://localhost:3333. The React frontend proxies all API requests to the http://localhost:3333 address.
+
+You can find a interactive GraphQL playground at http://localhost:3333/__graphql.
