+CLI Games is a community-driven collection of games that could be run in your terminal! Currently this project has many games including,
+- Hangman
+- Maze Escape
+- Text Adventures
+- Tic-Tac-Toe
+
+*And more in the future!*
+
+# How to Install?
+
+Installation is very simple.
+
+```bash
+#Clone the repo
+git clone https://github.com/salifm/cli-games.git
+cd cli-games
+```
+
+# How to Play?
+
+After cloning, run `ls` *(or `dir` on Windows)* to get a list of available directories of games. Then navigate to your favourite game using the `cd` command
+
+**Eg:** `cd Hangman`
+
+Read the **README** file in the respective directory to get more instruction about installation and playing.
+Most of the games support different languages (including `node-js` and `python`) and the choice is yours!

+Before creating a new game, please check if it is available already, or somebody is working on creating that game. Then make sure to create a new issue to make sure others are OK with it. If you got approval for your suggestion, then move one! Code your game and create a PR with the new changes. We'll be happy to introduce your new game :smile:
