 * Create a new `*.nix` file in the shells directory that describes the environment (this is the hard part).
 
-* Execute `lorri init` in the base directory of your project. This will create a `.envrc` file and `shell.nix` file.
+* Execute `use_nix > .envrc` to initialize the `.envrc` file.
 
-* Edit the `shell.nix` file so that it contains `import /path/to/this/repo/shells/your-new-file.nix`.
+* Execute `ln -s /path/to/correct/file.nix shell.nix`.
 
-* For shells that have a shellHook that exports environment containing computed directories (e.g. the git root or the current working directory), add `eval "$shellHook"` to your `.envrc`.
+* Execute `direnv allow` to load the `.envrc` file which in turn loads your environment.
