!!! tip
|
||||
|
||||
If an environment variable `<VAR>__FILE` is set and points to a valid file, the content of that file will be loaded into `<VAR>`.
|
||||
If an environment variable `<VAR>__FILE` is set with a valid file path as the value, the content of that file will become the value for `<VAR>` (_provided `<VAR>` has not already been set_).
