+After exporting files for release and preparing the package version for [DeployEx](https://github.com/thiagoesteves/deployex), run the following commands if testing locally:
+```sh
+export app_name=cochito
+export release_path=erlang-shipment
+cd build
+tar -czvf ${release_path}/${app_name}-0.1.0.tar.gz ${release_path}

 ## Architecture
 
 Currently the whole server just sits as a single file at `src/cochito.gleam`, these are the main libraries being used:
