+## HowTo add a specif ssh-key for your git account
+Sometimes it might be useful to have different ssh-keys per project or have a special ssh-key just for github/gitlab.
+
+Steps:
+1. Generate a `ssh-keygen`
+2. Add ssh-key to GitHub or GitLab account under settings
+3. Write a `~/.ssh/config` file with a content like this
+
+```
+Host github.com
+ HostName github.com
+ User git
+ IdentityFile ~/.ssh/id_rsa_for_git
+
+Host gitlab.com
+ HostName gitlab.com
+ User git
+ IdentityFile ~/.ssh/id_rsa_for_gitlab
+```
+Make sure that you adjust the `Hostname` accordingly and be sure that you use ssh in your git repo:
+```bash
+$ git remote -v
+origin git@github.com:USER/repo.git (fetch)
+origin git@github.com:USER/repo.git (push)
+```
+show no `https` in the urls.
