 ## Current Limitation
 
 - Both formulae are macOS arm64 only. The upstream releases do not ship a `darwin_amd64` asset today; add one upstream and the updater scripts can gain an `on_intel` block.

 - if none are set, it falls back to `gh auth token`

+For `tabex`, the formula caveat currently points users at:
+
+```bash
+tabex setup
+```
+
+That is intentional. `v0.0.4` is the first stable release that ships the source-repo-side `setup` flow, so the tap can now safely point users at the real first-run path instead of a generic help screen.

 ## Package-Manager Install Behavior
 
 Both private formulae use install-side GitHub auth:
