-> NOTES:
->
-> - You have to create the SQLite DB (`data.db`) and configuration (`config.toml`) before running the tracker. See `bin/install.sh`.
-> - You have to replace the user UID (`1000`) with yours.
-> - Remember to switch to your default docker context `docker context use default`.
+In both cases, you will need to:
+
+- Create the SQLite DB (`data.db`) if you are going to use SQLite.
+- Create the configuration file (`config.toml`) before running the tracker.
+- Replace the user UID (`1000`) with yours.
+
+> NOTICE: that the `./bin/install.sh` can setup the application for you. But it
+uses a predefined configuration.
+
+Remember to switch to your default docker context `docker context use default`
+and to change the API default configuration in `config.toml` to make it
+available from the host machine:
+
+```toml
+[http_api]
