From the Alibre start window, click the Utilities Tab and the Templates Directory under Miscellaneous.
Open the file alibre_unicode_custom.thd and add the following lines to the bottom.

Be sure to save the file in unicode format, maybe even get Notepad++ (free) to edit the file with.
Close Alibre and reopen it. The file is only read on startup.
You will then find BSP under User English.
Here is the documentation, such as it was.
