The English help files are included "hotpot v2" zip, but you have to move the help folder as follows:
- from: moodle/mod/hotpot/lang/en/help
- to: moodle/lang/en/help
The hotpot help files have been translated into many other languages, and you can probably get the language pack you require from the Moodle download
I suggest you do NOT install the whole language pack, because it might be for a different version of Moodle and some of the other modules might complain. Instead, I suggest you unzip the language pack somewhere on your local PC and just extract the hotpot help files and upload
those to your Moodle site.
For example, if you want the Spanish language help files for the hotpot module they will be in the following location in the "es" language pack:
and you should put them into the following place in Moodle
