+The easiest way to add your own configuration is:
+
+1. Get inspired by the configuration in `main/configs/demo`.
+2. Choose your `<your-config>`: a string obeying regex `[a-z0-9-]+`; directory `main/configs/<your-config>` should not yet be in use.
+3. Add your own queries in the `main/configs/<your-config>/public/queries` directory and in general, your own resources in the `main/configs/<your-config>/public` directory.
+4. Add your own additional resources in `main/configs/<your-config>/public`, if the defaults you'll get from `main/config-defaults/public` are not satisfactory for you.
+5. Write your own `main/configs/<your-config>/config.json` file, following the [configuration file documentation above](#configuration-file).
+6. Run or build as documented above for the `demo` configuration, of course now using `<your-config>`.
+7. Consider a pull request to add your configuration to this repo.
