+Update the htpdate User Agent
+=============================
+
+We want to use the same user agent in our htpdate script (see the
+[[Time syncing design|contribute/design/Time_syncing]]
+for more info on that) as in Tor Browser.
+
+To find out the User Agent of the new Tor Browser:
+
+1. Start Tor Browser (outside of Tails, if there is no ISO yet with the new
+   Tor Browser)
+2. Open the _Network_ tab in the _Developer Tools_ (Ctrl+Shift+E)
+3. Load a website (e.g. <https://tails.boum.org>)
+4. Select one of the GET requests in the _Developer Tools_
+5. Scroll down to `User-Agent` in the _Request headers_ section
+
+Now replace the User Agent in `config/chroot_local-includes/etc/default/htpdate.user-agent` with the one you found above.
