-# Section 0 RTA Handbook

-This hosted Git repo is intentionally plain Markdown. It has no required RTA
-sidecars. Collaborators clone, edit, commit, and push it as the canonical
-documentation source. The projection operator reads a separate projector
-checkout and mirrors the Markdown into AFFiNE as read-only docs.
+These documents are available in two ways:
+
+1. Read them in AFFiNE.
+   AFFiNE is the shared reading and whiteboard space. The Markdown docs from
+   this repo appear there as read-only copies.
+
+2. Edit them in Git.
+   The editable files live in this plain Markdown repo. Use your normal editor,
+   then commit and push changes.
+
+If you want to change one of these docs, edit the Markdown file. Do not edit
+the AFFiNE copy; it will be refreshed from Git.
 
 ## What To Edit
 
-Edit Markdown files in this Git repo. Do not edit the projected AFFiNE copies
-directly; AFFiNE is the shared reading and canvas surface, not the source of
-truth for these files.
