Google Docs Add-on that lets you preview Markdown with Github styling.
⚠️⚠️⚠️ ATTENTION ⚠️⚠️⚠️

As a developer of Markdown Preview, I need to warn you that add-on WON'T WORK if you are logged in on multiple Google Accounts in your browser. This bug is related to Google's engine and only Google can fix it. 

You can read about the issue here
By starring the issue, you make the issue a priority to Google's team.

The workaround is to log out of all Google Accounts except the one that is using the add-on. 

Thank you for your understanding.


The Add-on has an auto-refresh option that updates the preview as you type every X milliseconds. By default, it is set to 5000ms (5 seconds).
The option can be found in Add-ons > Markdown Preview > Settings

NOTE: If you have a slower machine, don't reduce this value!
It can cause high CPU usage. To disable auto-refresh, set the update interval to 0.

Markdown Preview has a "Refresh" button at the bottom of the sidebar that allows you to manually update the preview.
To keep the UI clean, the button is only visible when you hover over it with your mouse.


Markdown preview needs following permissions to run:
  - Email (included by default)
  - Profile Info (included by default)
  - Read the content of opened file -> Read your Markdown
  - Display third party content -> Show sidebars and modals


Issues and feature requests are welcome!
If this Add-on helped you, please consider leaving a 5 ⭐ rating.

No longer works, even with a simple test file such as: ``` # hi test1 ## h2 test2 ### h3 test3 ``` The "Markdown Preview" sidebar just shows a loading spinner forever.
