 Your website appears with a "light" white and gray background by default, with dark text. You can quickly switch to a "dark" background with white text by changing the line in your `_config.yml` file that reads `style: light` to `style: dark`.
 
+#### Projects
+
+The "My Projects" section of your website is generated by default with your nine most recently "pushed" repositories. It also excludes repositories that you forked, by default. But each of these parameters can be quickly customized in your repository's `_config.yml` file, under the `projects` dictionary line.
+
+Parameters include:
+
+- `sort_by`: The method by which repositories are sorted. Options include `pushed` and `stars`.
+- `limit`: The maximum number of repositories that will be displayed in the "My Projects" section of your website. Out of the box, this number is set to `9`.
+- `exclude`:
+   - `forks`: When `true`, repositories you've forked will be excluded from the listing.
+   - `projects`: A list the repository names you want to exclude from the listing.
+
 #### Topics
