+# The Jump-and-Run Game
+
+Welcome to `jump_and_run_game` – a fun and exciting jump-and-run game developed
+in Python!
+
+## Overview
+
+It's really just a simple Jump- and Run game: 2D, jumping ... and walking.
+Let's be honest, it's not running so far.

+
+## Installation
+
+1. Ensure you have Python 3.8 or later installed.
+
+2. Install dependencies:
+
+    ```bash
+    pip install jump_and_run_game
+    ```
+
+## Usage
+
+To play the game, run the following command:
+
+```bash
+jump_and_run_game
+```
+
+This is how it looks like at the moment:

+
+## Controls
+
+* Left Arrow: Move the player left.
+* Right Arrow: Move the player right.
+* Space: Make the player jump.
+
+## Contributing

+
+It's typically wise to open an issue first and wait for feedback, before adding
+tons of code that might get rejected.
