Markdown (issue panel)
The main working surface. One tab per .md attachment on the issue (extra tabs collapse into a 'More (n)' menu), a read-only rendered preview of the selected tab, a sort button, Edit and Add buttons, and a Delete icon on each tab with a confirmation dialog. The panel refreshes itself when Jira reports the issue changed, so files attached through Jira's own attachment control appear without a reload.

#Worth knowing
The panel reads the issue's attachments directly, so it shows every .md file on the issue, including ones attached before the app was installed.
#Where to find it
Issue view > Markdown panel

#When there are no documents
The panel reads 'No markdown documents added to this issue' and shows a single Add Markdown button.
#Where you do it
Task | Where |
|---|---|
Make the Markdown panel always visible on issues | Jira project settings > Issue layout |
Add a Markdown document to an issue | Issue view > Markdown panel > Add |
Read a Markdown document | Issue view > Markdown panel |
#Settings that affect this

Setting | Where | What it does |
|---|---|---|
Sort tabs | Issue view > Markdown panel > sort button | Switches the tabs between newest first and A to Z. The choice is saved on the issue, so everyone sees the same order. The button is hidden on narrow screens. |
#A few things that catch people out
There is no version history for a Markdown document, neither in Jira nor in the app.
Nothing prevents two documents on the same issue having the same title, and renaming makes the old filename disappear.
Raw HTML inside a Markdown document is not rendered.
Relative image paths, such as
./diagram.png, do not resolve in Jira. Use a full web address.Content that does not look like Markdown can be replaced by an 'Invalid markdown provided' message naming the detected language.
