# Cannot restrict who adds Markdown or configure diagram languages

**What you are seeing**

There is no way to restrict who can add Markdown, turn diagram languages on or off, point diagrams at your own renderer, or manage approved domains.

---

## Why it happens

Markdown for Jira has no administration or project settings. Documents are ordinary Jira attachments, so Jira's own permissions decide who can add, edit and delete them, and every diagram is drawn by Capable's hosted service.

---

## What to do

These are not configurable in the Jira edition. Control access through normal Jira issue and attachment permissions instead.

## A few things that catch people out

* Logged-out and anonymous users never see either surface; there is no anonymous or unlicensed read-only mode.
* There is no admin or project-level configuration at all: no access restrictions, no diagram-language toggles, no self-hosted renderer setting, no approved-domain management.
