 Nearly all Markdown applications support the basic syntax outlined in the original Markdown design document. There are minor variations and discrepancies between Markdown processors — those are noted inline wherever possible.
 
+## Headings
+
+To create a heading, add number signs (`#`) in front of a word or phrase. The number of number signs you use should correspond to the heading level. For example, to create a heading level three (`<h3>`), use three number signs (e.g., `### My Header`).
+
+| Markdown                 | HTML                       | Rendered Output |
+| ------------------------ | -------------------------- | --------------- |
+| `# Heading level 1`      | `<h1>Heading level 1</h1>` | Heading level 1 |
+| `## Heading level 2`     | `<h2>Heading level 2</h2>` | Heading level 2 |
+| `### Heading level 3`    | `<h3>Heading level 3</h3>` | Heading level 3 |
+| `#### Heading level 4`   | `<h4>Heading level 4</h4>` | Heading level 4 |
+| `##### Heading level 5`  | `<h5>Heading level 5</h5>` | Heading level 5 |
+| `###### Heading level 6` | `<h6>Heading level 6</h6>` | Heading level 6 |
+
+### Alternate Syntax
+
+Alternatively, on the line below the text, add any number of `==` characters for heading level 1 or `--` characters for heading level 2.
+
+| Markdown                         | HTML                       | Rendered Output |
+| -------------------------------- | -------------------------- | --------------- |
+| `Heading level 1===============` | `<h1>Heading level 1</h1>` | Heading level 1 |
+| `Heading level 2---------------` | `<h2>Heading level 2</h2>` | Heading level 2 |
+
+### Heading Best Practices
+
+Markdown applications don’t agree on how to handle a missing space between the number signs (`#`) and the heading name. For compatibility, always put a space between the number signs and the heading name.
+
+| ✅ Do this            | ❌ Don't do this     |
+| -------------------- | ------------------- |
+| `# Here's a Heading` | `#Here's a Heading` |
+
+You should also put blank lines before and after a heading for compatibility.

 ## Paragraphs
 
 To create paragraphs, use a blank line to separate one or more lines of text.

 Use blank lines to separate block-level HTML elements like `<div>`, `<table>`, `<pre>`, and `<p>` from the surrounding content. Try not to indent the tags with tabs or spaces — that can interfere with the formatting.
