+Rudric includes support for [`direnv`](https://github.com/direnv/direnv). However, in order to use it, you will have to start a Rudric session before using `direnv`.
+
+Simply add the following to your `.envrc` file:
+
+```
+$(rudric env direnv)
+```
+
+Changing into the directory with both a `.envrc` and `.renv` file will automatically source your encrypted secrets in the environment.
+
+> ![IMPORTANT]
+> If a valid session token is not set, changing into a directory with a trusted `.envrc` will prompt you for your password. This will fail as input will not be passed to Rudric. I'm working on a solution for this but for now, start a session with `rudric session` first.

 # Crates
 
 Encryption is all accomplished using the fantastic [Orion](https://github.com/orion-rs/orion) library.
