+Commands
+========
+
+Commands in ZoiteChat are prefixed with **/** and to escape them you can type it twice e.g. **//**
+
+ZoiteChat will first try to run plugin commands, then user commands, then client commands, and lastly send it directly to the server.
+
+User Commands
+-------------
+
+User commands can be used to create aliases, to run multiple commands at a time, or more complex custom commands. They are set in :menuselection:`Settings --> User Commands`.
+
+An alias is just a shortcut refering to an existing command, for example */j* refers to */join &2*
+
+Naming two user commands the same thing will run both in the order they are listed.
+
+For more complex commands you can use these codes:
+
+- **%c** Current channel
+- **%e** Current network
+- **%m** Machine info
+- **%n** Your nick
+- **%t** Time/date
+- **%v** ZoiteChat version
+- **%<num>** Word
