+
+  First add the repository to your inputs.
+
+  Point to main branch:
+
+  ```nix
+  inputs = {
+      ...
+      gitv.url = "github:JayanAXHF/gitv";
+      ...
+  };
+  ```
+
+  Point to a rev in main branch:
+
+  ```nix
+  inputs = {
+      ...
+      gitv.url = "github:JayanAXHF/gitv/d70273b05c5e80b05446e4aa0847758e54435d62";
+      ...
+  };
+  ```
+
+  Point to a tag:
+
+  ```nix
+  inputs = {
+      ...
+      gitv.url = "github:JayanAXHF/gitv/refs/tags/gitv-tui-v0.3.2";
+      ...
+  };
+  ```
+
+  Then your outputs should look something like this:
+
+  ```nix
+  outputs = {...} @ inputs: { 
+    # Don't forget to add nixpkgs to your inputs
+    nixosConfigurations."nixos" = inputs.nixpkgs.lib.nixosSystem {
+      ...
+      specialArgs = {inherit inputs;};
+      modules = [
+        ./configuration.nix
+        ... 
+      ];
+    };
+  };
+  ```
+
+  And finally, somewhere in your `configuration.nix`:
+
+  ```nix
+  {inputs, pkgs, ...}: {
+    ...
+    environment.systemPackages = [
+      inputs.gitv.packages.${pkgs.stdenv.hostPlatform.system}.default
+    ];
+    ...
+  }
+  ```

+  <summary>Non-Flake</summary>
+
+  ##### Pinning Tool
+
+  First add the pin using your pinning tool.
+
+  We are going to show examples using npins.
+
+  Point to a branch:
+
+  ```bash
+  npins add github JayanAXHF gitv -b main
+  ```
+
+  Point to a rev in main branch:
+
+  ```bash
+  npins add github JayanAXHF gitv -b main --at d70273b05c5e80b05446e4aa0847758e54435d62
+  ```
+
+  Point to a tag:
+
+  ```bash
+  npins add github JayanAXHF gitv --at gitv-tui-v0.3.2
+  ```
+
+  Or point to latest release:
+
+  ```bash
+  npins add github JayanAXHF gitv
+  ```
+
+  Then add the package to your `systemPackages`:
+
+  ```nix
+  let
+    sources = import ./npins;
+  in {
+    environment.systemPackages = [
+      (import sources.gitv)
+    ];
+  }
+  ```
+
+  ##### No Pinning Tool
+
+  ```nix
+  let
+    rev = "d70273b05c5e80b05446e4aa0847758e54435d62";
+    gitv = import (fetchTarball "https://github.com/JayanAXHF/gitv/archive/${rev}.tar.gz") {};
+  in {
+    environment.systemPackages = [
+      gitv
+    ];
+  }
+  ```

 > [!TIP]
 > Run the `init.py` initialization script to set up your development environment. It installs a pre-push hook that runs `typos` and `clippy` to help maintain code quality and consistency. Ensure that you have the `typos-cli` installed and available in your PATH for the pre-push hook to work correctly. You can install it using `cargo install typos-cli`.
 
+ [!TIP]
+> If you're using nix then you can use the provided devshell to get your development environment up and running, it also includes the pre-push hook provided. You can do so by executing `direnv allow` or `nix develop`.
