Overview template

# Introduction to the Overview Page
The Overview page is a summary of all the other microchapters. The overview page for a microchaptered page will show the main subtitles of the page, with a brief overview of the content of each microchapter within each subtitle. This page is best created last, and aims to summarize the important aspects of the disease. To see an example of an Overview page on Pericarditis within a microchaptered page, click here. The aim is to convey the most important information for a "quick glance" at the disease. Below is the general template to follow when creating an Overview for a microchaptered page. Whether all the subheadings are needed and how extensive they are, will depend on the complexity of the disease page you are creating.

# Overview
