This plugin will allow creation of admin help tabs (and associated sidebars) on any screen in the WordPress admin area. It creates a custom post type called Help Tabs to store information. You need to add the following info to make it work:
<ol>
<li>Title – The title of your tab</li>
<li>Main content area </li>
<li>Screen – What page/screen it should appear on</li>
<li>Type – Help tab or tab sidebar</li>
</ol>
HELP TAB EXAMPLE: 
Let’s say I want to add a help tab on the main Help Tabs listing page that says something about my plugin. I would use:
<ol>
<li>“My Main Tab”</li>
<li>“This is a main tab with my own info on it!”</li>
<li>“edit-sbah_helptab”</li>
<li>Select “Tab” (the default)</li>
</ol>
HELP SIDEBAR EXAMPLE: 
Let’s say I want to add a help sidebar (these are the areas to the right with extra info and links) on the main Help Tabs listing page. I would use:
<ol>
<li>“My Sidebar”</li>
<li>“This is a sidebar!”</li>
<li>“edit-sbah_helptab”</li>
<li>Select “Sidebar”</li>
</ol>
IMPORTANT NOTE: While there can be multiple tabs per page, there can be only ONE sidebar per page. If you add others to the same page, only the first one found will show.
NOTE: I also have a plugin that does Admin Pointers (those blue info boxes), if you are interested in that one you can find it here: https://wordpress.org/plugins/better-admin-pointers/
This plugin leverages the great work done by others here:
