# Config

We use this crate to handle the environment variables. It allows us to use them in a more secured way than just using the env::var("MY_VARIABLE") standard function, as the app will not run if a variable is missing.

# Add more variables

To add more variables, first add them to your .env file. Then, you can add them to the crates/config/src/lib.rs file, more precisely to the get_from_env function. You can also add a default value by passing a second parameter, and a visibility in the third one (one of Public, Private).
