+# How to create your SSH Keys
+
+You need to connect your computer to your GitLab account through SSH Keys. They are unique for every computer that you link with your GitLab account with.
+
+## Generate your SSH Key
+
+* Create an account on GitLab. Sign up and check your email for your confirmation link
+
+* After you confirm, go to [gitlab.com](https://about.gitlab.com/) and sign in to your account
+
+## Add your SSH Key
+
+* At the top right corner, click on "profile settings"

+## Things to know when using your commandline
+	
+1. Don’t use capital letters 
+
+1. You need to find out how your directory is structured. The structure is like a tree, so you won’t be able to access one subfolder unless you open the main folder where it is contained. Directories are folders or files in your system. 
+
+1. You can change multiple pages in one commit. A branch consists of multiple commits. 
+
+1. The terminal will add changes locally in your computer, that you later need to send to gitlab.com.
+
+1. You can add changes directly into your computer files after you tell the terminal: “git pull NAME OF DOC”, and then you can send those changes to GitLab through the terminal. (changes like adding files, changing names, adding pictures to files, etc)
