+# General
+
+GIT is a version control software, that allows you to save the progress of software/text/whatever development.
+It is probably best know from GitHub, but we will show how to set up your own GIT instance and how to use it.
+
+## Installing GIT
+
+### What you need
+
+1. A working server, being it self-hosted at home or a remote instance, called REMOTE in the following
+2. A local machine that you develop whatever on, called LOCAL in the following
+
+### Installing GIT
+
+On the LOCAL machine, use your favorite package manager, for example
+
+```sh
+pacman -S git
+```
+
+The same holds for the REMOTE machine, but here I would advice, to use some LTS distro, so probably
+
+```sh
+sudo apt install git
+```
+
+### Setting up the Server
+
+First we have to add the git-user on the REMOTE, give him a password and enable ssh logins.
+
+```sh
+sudo adduser git
+su git
+passwd
+cd
+mkdir .ssh & chmod 700 .ssh
+touch .ssh/authorized_keys && chmod 600 .ssh/authorized_keys
+```
+Now add the ssh public keys of your LOCAL machine to the `authorized_keys` file on the REMOTE.
+For this on the LOCAL machine generate a key-pair using `ssh-keygen -t rsa` if you don't have one yet.
+Then copy the content of `LOCAL/.ssh/id_rsa.pub` to the `REMOTE/.ssh/authorized_keys` file.
+
+## New Repository
+
+To initialize a repository on the REMOTE server we have to create a new folder and tell git to track this folder.
+This has to be done once for every new repository.
+
+```sh
+cd
+mkdir NewRepo.git
+cd NewRepo.git
+git init --bare
+```
+
+On the LOCAL machine we then have to create a folder and tell git to sync this with the server.
+We will assume that `REMOTE` is either the IP or the domain-name of the REMOTE instance.
+
+```sh
+cd project
+git init
+git add .
+git commit -m 'Initial commit'
+git remote add origin git@REMOTE:/home/git/NewRepo.git
+git push origin master
+```
+
+## Using Git
+
+To now sync this folder to other devices use
+
+```sh
+git clone git@gitserver:/home/git/NewRepo.git
+cd project
+```
+
+To update the repository go to the folder, add the necessary files using `git add <FILES>` and then commit them using `git commit -m '<MESSAGE>`. These steps can be done as one using
+
+```sh
+git commit -am 'Fix for README file'
+```
+
+Now push it to the server using `git push origin master`.

 The next step is to make the `authorized_keys` file using

 Now open the `authorized_keys` and copy-paste the public key contents in to it.
 
 One can also use `ssh-copy-id user@domain` after generating the key-pair.
