mindmeister-markdown is a Chrome add-on developed by Joe Jackson that adds markdown support to MindMeister notes. This add-on is designed to enhance the note-taking capabilities of MindMeister by allowing users to use markdown formatting in their notes.

To utilize this add-on, users simply need to add a note in MindMeister, click on "advanced," and then select "switch to plain text." From there, users can enter their markdown text. It is important to note that the first line of the note must be "MARKDOWN" to activate the markdown formatting.

With mindmeister-markdown, users can easily create headers, lists, and other formatting elements using markdown syntax. This add-on provides a quick and efficient way for MindMeister users to format their notes in a more structured and organized manner.
