The help manager centralizes script help GUIs and provides a simple way to add instructions. Users can be notified with a popup the first time a resource's help page is loaded.
If you just want to add a text, adding this exact (don't change src nor type) line to your meta.xml will be enough:
<config src="help.xml" type="client"/>
The contents below the root node of your help.xml file will be shown under the resource's help tab. Also, an optional popup="no" can be added to the root node to specify that you don't want the user to be notified with a popup when the page is available.
<help popup="no"> Help text here </help>
Help text should explain how to play the gamemode, bound keys and console commands. The help is intended for the end user, not the developer so keep it simple.
You can add your custom help GUI by adding the tab manually in a client script:
myHelpTab = call(getResourceFromName("helpmanager"), "addHelpTab", getThisResource(), true)
You can add contents by using the returned GUI element as GUI parent for your widgets. It is not necessary to destroy them on page remove / resource stop, as the manager does cleanup.
