+# Installation of Git
+
+Several git clients are presented [here](https://howto.lcsb.uni.lu/?contribute:git-clients).
+
+For most of the git clients, `git` is actually required to be installed on the system. You can find installers for Windows, MacOS and Linux on the [Git webpage](https://git-scm.com/downloads).
+
+If you are using Visual Studio Code, and if you want to contribute to a repository hosted on the [LCSB Gitlab](https://git-r3lab.uni.lu), you will need to verify the host key first before you are able to clone or push to a repository. For this, open a terminal (on Linux or macOS) or Git Bash (on Windows), and type:
+```bash
+ssh git@git-r3lab-server.uni.lu -p8022
+```
+Then, press Enter and type `yes`. This will add the git-r3lab server to the known hosts on your system.
