Next to the theme that you want to edit click on the Menu button which is a small square with 3 blue dots
This will open a submenu of options which includes: Edit HTMl / CSS and Edit Language
The choices are:

Headings Used for all page and section titles
H1 The H1 tag is extremely important for SEO across your site and is used for all page titles.
H2, H3, H4 These tags are used for additional headings. Generally H2 will be higher up the page whereas H4 is lower
H5 and H6 are not used in the theme files at all but can be used by selecting them within Shopify's Rich Text Editor
