1. Unordered List Markers

You can create an unordered bullet item using any of three characters: dash (-), *asterisk (`)**, or **plus (+`)**, followed by a space:

2. Nested Unordered Lists

To nest a sub-list inside an existing list item, indent the sub-items by 2 or 4 spaces (or 1 Tab):

3. Tight vs. Loose Lists (Spacing Matters!)

Understanding the difference between tight and loose lists is a mark of an experienced Markdown writer:

Tight List (No paragraph wrapping):

When items have no blank lines between them, the HTML compiles without <p> tags inside the <li>:

HTML: <li>Clean item 1</li>

Loose List (With paragraph wrapping):

If you insert a blank line between any items in the list, the entire list becomes "loose", wrapping each item in <p> tags with extra paragraph margins:

HTML: <li><p>Detailed item 1 with extensive explanation.</p></li>
