The HTML Help output for MPLAB Harmony has two purposes. First, it can be used as "stand-alone" Help. Second, the HTML files are used by the MPLAB Harmony Configurator (MHC) when using MHC in MPLAB X IDE. 

Stand-alone HTML Help 

The MPLAB Harmony index.html file that is the root for all HTML help is located in the ./doc subfolder of the package it documents. For example, documentation on the MPLAB Harmony 3 Configurator is found at ./mhc/doc/index.html and documentation on the MPLAB Harmony Graphics Library is found at ./gfx/doc/index.html. 

To use the HTML Help in a "stand-alone" manner, open the file index.html in your browser of choice. Click Allow blocked content if a message appears regarding ActiveX controls.

The following links are provided:

• Table of Contents - Located at the top left, clicking this link opens the Table of Contents in the right frame
• Topic Path - At the top and bottom of each topic, the full path to the current topic is listed
• Microchip Logo - Clicking this image opens a new browser tab and displays the Microchip website (www.microchip.com)
• Contents - The Contents topic is a static file, which displays and lists the major sections available in the Help in the left frame. Due to a restriction with the Help browser used by the MHC, a dynamic Contents topic cannot be used.
• Home - This link returns to the Introduction topic (see Note 1)
• Previous and Next navigation links - Use these links to traverse through the Help topics
• Documentation Feedback - Use this link to provide feedback in the form of an email (see Note 2)
• Microchip Support - Use this link to open the Support page of the Microchip website

Notes:

The Home link does not appear initially. Once you begin traversing the topics, it dynamically appears. To use the Documentation Feedback link, you must have an email system such as Outlook configured. Clicking the link automatically opens a new email message and populates the recipient and subject lines.
