-  Paste it ONCE and you're done forever: it puts the watcher repo in
-  %USERPROFILE%\eve-watcher, runs update.py, and update.py registers a Windows
-  Scheduled Task that auto-updates + restarts the watchers at every logon and
-  once a day. You never have to install or update again.
+  Paste it ONCE. It puts the watcher repo in %USERPROFILE%\eve-watcher, forces the
+  working tree to match the latest code, and runs update.py - which installs deps +
+  Tesseract, starts the watchers, auto-detects the ore-hold readout (no manual snip),
+  and registers logon + daily auto-update. You never have to install or update again.
 
-  Safe to re-run: if the folder already exists (even from the old non-git
-  installer) it is converted into a git clone in place, keeping your config.ini
-  (webhook + OCR snip). config.ini is gitignored, so updates never touch it.
+  Safe to re-run anytime: it force-syncs to the latest code (reset --hard) and never
+  touches your gitignored config.ini.
