+## history
+
+Provides a couple of convenient aliases for using the `history` command to examine your command line history.
+
+### Requirements
+
+* None.
+
+### Usage
+
+* If `h` is called, your command history is listed. Equivalent to using `history`
+
+* If `hsi` is called with an argument, a **case insensitive** `grep` search is performed on your command history, looking for commands that match the argument provided
+
+* If `hsi` is called without an argument you will help on `grep` arguments
