+# client/command/aka
+
+## Overview
+
+Implements the 'aka' command group for the Sliver client console. "Aka"s are
+command aliases (like 'alias' in 'bash') that allow operators to specify
+shorthand commands and default arguments for commonly used commands.
+
+### Examples:
+
+- `aka create bg background`: Allows an operator to run `bg` from the implant 
+menu to quickly move back to the server menu
+- `aka create execw execute -o "C:\Windows\System32\cmd.exe" /c`: Shorthand for
+  executing binaries on Windows targets like: `execw arp -a`
+
+## Go Files
+
+- `commands.go` – Wires Cobra commands for listing, creating, and deleting command aliases in the client console.
+- `create.go` – Handles creating command aliases to use by the client.
+- `delete.go` – Removes command aliases currently tracked by the client. 
+- `hook.go` – The main hooking logic to intercept commands ran by the client console. The hook will intercept processing before hitting the Cobra tree to transform the command alias to a full command with default arguments from the command alias and user-provided arguments to the alias.
+- `list.go` - Lists the current command aliases tracked by the client.
+- `storage.go` - Supports the saving of aliases to disk to keep between runs of the client.
