+Syncthing doesn\(aqt have a direct way to do this, as it\(aqs potentially
+dangerous to do so if you\(aqre not careful \- it may result in data loss if
+something goes wrong during the move and is synchronized to your other
+devices.
+.sp
+The easy way to rename or move a synced folder on the local system is to
+remove the folder in the Syncthing UI, move it on disk, then re\-add it using
+the new path.
+.sp
+It\(aqs best to do this when the folder is already in sync between your
+devices, as it is otherwise unpredictable which changes will "win" after the
+move. Changes made on other devices may be overwritten, or changed made
+locally may be overwritten by those on other devices.
+.sp
+An alternative way is to shut down Syncthing, move the folder on disk, edit
+the path directly in the configuration file and then start Syncthing again.

+.SS Why do I get "Host check error" in the GUI/API?
+.sp
+Syncthing since version 0.14.6 does an extra security check when the GUI/API
+is bound to localhost \- namely that the browser is talking to localhost.
+This protects against most forms of \fI\%DNS rebinding attack\fP <\fBhttps://en.wikipedia.org/wiki/DNS_rebinding\fP> against the GUI.
+.sp
+To pass this test, ensure that you are accessing the GUI using an URL that
+begins with \fIhttp://localhost\fP, \fIhttp://127.0.0.1\fP or \fIhttp://[::1]\fP\&. HTTPS
