 # tourmaline
+
 Tourmaline is a (planned) agnostic, asynchronous and awesome installer framework
+
+
+## Usage
+
+Just run `cargo run -- help` or `trm help` for now.
+
+
+## Scripts
+
+Scripts for all supported distros are stored in the `config` folder of this repository.
+Each distro has its own folder with several subfolders corresponding to all integration tasks.
+
+```
+<distro>
+  | <task>
+      | up.nu
+      | down.nu 
+  | <task>
+      | up.nu
+      | down.nu
+```
+
+The `up.nu` scripts contain the required steps to apply the change described by the task.
+This can include installing packages, creating configuration files and starting systemd units.
+
+The `down.nu` scripts contain the steps to revert the change applied by a task. These scripts will
+later be used to offer functionalities like reinstalling grub or changing installed kernels.
