+# SSH config files
+
+## brief
+This is the first time for me using ssh config files so that's why this is a seperate file.
+
+## What can you do with ssh config files
+In SSH config files you can describe how connections should be handled and with which keys you want to use to log in onto a specific server and much more.
+
+## How is a config file structured
+```config
+Host hostname1
+    SSH_OPTION value
+    SSH_OPTION value
+
+Host hostname2
+    SSH_OPTION value
+
+Host *
+    SSH_OPTION value
+```
+A entry always start with `Host` and then the name you wanna give to that host. After that you press enter and then tab. Now you can define the options for the ssh connections.
+
+Example:
+```config
+HOST gitwaag
+        Hostname gitlab.waag.org
+        User git
+        IdentityFile ~/.ssh/id_ed25519
+        IdentitiesOnly yes
+```
+In this config I defined the host as gitwaag. So I can connect to it using the command ```ssh gitwaag``` instead of ```ssh gitlab.waag.org```.
+
+#### Explanation of the parameters used in this config above
+* `Hostname` Defines the hostname/domain of the server
+* `User` The username you wanna log in as on the server
+* `IdentityFile` Which public key you want to use for the connection
+* `IdentitiesOnly` Set it to only use the IdentityFile instead of other authentication files.
