Hi Aaron,
One option is to build simple 'customhelp' addon module. Attaching simple addon with one help page. You can enhance this based on your need.
In case you want to test addon -
1. Download & extract addon to '/www/addons folder
2. Change help link code (line # 51) in www/core/components/sidemenu/templates/menu.html as below -
<a menu-close class="item item-icon-left" ui-sref="site.customhelp" mm-link title="{{ 'mm.sidemenu.help' | translate}}">If everything is okay, you will see local custom help page with couple of FAQ questions when you click help on side menu.
Hope it helps.
Hi Manjunath
Thank you for the addon ZIP - looks to be what I'm after!
I've done what you said with changing Line #51 and adding the files to the /addons folder, but the 'help' option is no longer a clickable action; if I mouse over the mouse doesn't change, and clicking it just hides the sidebar.
I've attached a screenshot of the sidebar. Is there something else which I need to do, please? 
Thank you
Aaron,
hope you are using 'moodle mobile 2' repo as base & running gulp after making changes.
Here is exact change I made in menu.html -
Before
<a menu-close class="item item-icon-left" ng-href="{{docsurl}}" mm-link title="{{ 'mm.sidemenu.help' | translate}}">After
<a menu-close class="item item-icon-left" ui-sref="site.customhelp" mm-link title="{{ 'mm.sidemenu.help' | translate}}">I'm using the PhoneGap build from GitHub [https://github.com/moodlehq/moodlemobile-phonegapbuild]
I couldn't get half of the dependencies installed on my machine for the Moodle Mobile 2 repository, so having to use PhoneGap on MAMP 3
Aaron,
Even through you are including new add-on module correctly, your custom module js files (main.js) may not be getting updated into 'mm.bundle.js' in the build folder (this is all-in-one js file included in index.html). May be this is why click is not working. Using 'moodle mobile2' repo & gulp would have taken care of this. Workaround (error prone) is to manually add your help module js file(s) code into 'mm.bundle.js'.
Manjunath,
Thank you for your patience. I had installed Node previously, and it had not uninstalled completely when I removed it before.
I've now got this page working through the Moodle Mobile 2 directory using Ionic. Thank you very much for your help.
For future reference in case anyone else requires help, I used the following YouTube video:

Thank you again! It's exactly what I needed!
