+Taskcafe offers 3 different configuration methods.
+
+## Environment Variables
+
+The first way is through `env` variables.
+
+The available env variables are
+
+- `TASKCAFE_DATABASE_HOST`: The IP of the database (ex: 127.0.0.1)
+- `TASKCAFE_DATABASE_USER`: The user for the database connection (ex: 'postgres')
+- `TASKCAFE_DATABASE_PASSWORD`: The password for the database connection
+- `TASKCAFE_DATABASE_NAME`: The name of the database (ex: 'taskcafe')
+- `TASKCAFE_MIGRATE`: Setting this to `true` will run the database schema migrations on application startup
+- `TASKCAFE_GENERAL_HOST`: The host and port to run the web service on (default is 0.0.0.0:3333)
+
+## Config file
+
+The same configuration options above can be set through a config file. See the [example config file](https://github.com/JordanKnott/taskcafe/blob/master/conf/taskcafe.example.toml) for more information.
+
+## CLI flags
+
+You can also set some of the config options through the CLI. Run `taskcafe web --help` for available options and flags.
