+## Commands
+
+Commands are easy to create and allow for greater editor usability. To create your own command, create a julia file in the `cmds` folder and name it after your command. Then include your file in the Acorn module. Below is an example definition of the command `sample`. For more examples, see the `cmds/` folder.
+
+
+### `cmds/sample.jl`
+
+```julia
+
+# The command must have the signature
+#   function(::Editor, ::String)
+function sampleCommand(ed::Editor, args::String)
+    # Perform operation here
+end
+
+# Call `addCommand` to add
+addCommand(:sample,                         # The command name
+            sampleCommand,                  # The command function
+            help="description of sample")   # Displayed when user runs 'help sample'
+```
+
+### `Acorn.jl`
+
+Include your command here
+
+```julia
+# Load commands
+#...
+include("cmds/save.jl")
+include("cmds/find.jl")
+include("cmds/sample.jl") # Add this line
+#...
