+Getting Started
+=========================
+
+Welcome to the **comeit** project! A linter for conventional commits. Follow the steps below to
+install and start using the package.
+
+1. **Install the package**:
+
+   You can install **comeit** directly from PyPI using `pip`:
+
+   .. code-block:: bash
+
+      pip install comeit
+
+2. **Run the application**
+
+  **comeit** includes a CLI tool, you can run it like this:
+
+  .. code-block:: bash
+
+    comeit
+
+  By default, ``comeit`` uses ``git`` internally with ``gitpython`` to read all the commits on the
+  current branch. These are the commits that are parsed and reported if nothing else is specified.
+
+
+You're ready to go! Explore the project documentation for further details.
