+# Shorten SSH Commands With Aliases
+
+Each time I need to SSH into one of my remote app boxes, like _staging_, I run a
+command like the following:
+
+```bash
+$ ssh root@staging-box.com
+```
+
+Instead of having to remember the user and domain, I can add aliases to my
+`~/.ssh/config` file.
+
+```
+# Staging Server
+Host staging
+    HostName staging-box.com
+    User root
+
+# Sandbox Server
+Host sandbox
+    HostName sandbox-box.com
+    User root
+```
+
+Then I can SSH to each of these like so:
+
+```bash
+$ ssh staging
+
+$ ssh sandbox
+```
+
+These aliases help a little bit, but they will help even more in situations
+where I need other settings configured for the SSH sessions like `Port` or
+`ForwardAgent`.
