+## Generate ssh keys
+Using the SSH protocol, you can connect and authenticate to remote servers and services. With SSH keys, you can connect to GitHub without supplying your username or password at each visit. You can now use ssh to clone the repo
+and initialize all submodules.

+**Generate a ssh key**
+```
+ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
+```
+## Adding your SSH key to the ssh-agent
+**Start the ssh-agent in the background**
+```
+eval "$(ssh-agent -s)"
+```
+**Add key to ssh agent**
+```
+ssh-add ~/.ssh/id_rsa
+```
+## Add to github
+The easiest way to do it is to use xclip but you can also copy the data inside the file.
+```
+xclip -sel clip < ~/.ssh/id_rsa.pub
+```
