 This extension will only run on GitHub domain and does the following on all markdown bodies on GitHub:
 
-- Creates a text overlay over all images with the alt text. This includes Pull Requests, Issues, Repo READMEs, and Discussions. 
-    - If an image is missing an alt text, it will appear with a red border. 
-    - **If an image has an empty string alt like `""`, it will also appear with a red border**. Typically, an empty string alt indicates that an image is decorative and should be hidden. However, on GitHub, all markdown images are rendered within a link element. Therefore, we recommend that all images in GitHub markdown have an alt text provided or the link will be announced without a bane,

 - Appends the heading level that is used after the heading text within markdown bodies. Heading levels are useful for conveying semantics for screenreader, and other assistive technology users. This similarly aims to bring mindfulness particularly for sighted users who may pay less attention to heading level semantics.

 ### Customization note
 
-The styling I've set may not be suitable for all users. Feel free to customize these however you like when you download these files. 
+The styling I've set may not be suitable for all users. Feel free to customize these however you like when you download these files.
 
 You can do this by modifying `styles.css`. There are CSS variables at the top which you may set to your preference. For example, you may choose to set a different color for each heading level or remove the border. If you'd prefer the headings to be positioned at the front, follow the notes in `contentScript.js`. Once changes are made, `Update` on `chrome://extensions/` so changes are reflected in the extension.
