+You can use this mechanism to install binaries from private GitLab repositories
+(GitHub not supported right now). If you need to pass a `PRIVATE-TOKEN` in the
+headers, you need to set the `token_env` key in the `list` and `fetch`
+sections. This key should contain the name of the environment variable that is
+set with the token.

+Here is an example file:
+
+```yaml
+$ cat ~/.config/binenv/distributions-custom.yaml
+---
+sources:
+  foo:
+    description: This tool let's you foo database tables
+    url: https://gitlab.exemple.org/infrastructure/tools/foo

+You will have to `export FOO_PRIVATE_TOKEN=your_token` before running `binenv`
+to make the token available.
