+.SH HOW DO I INCREASE THE INOTIFY LIMIT TO GET MY FILESYSTEM WATCHER TO WORK?

+You are probably reading this because you encountered the following error with
+the filesystem watcher on linux:
+.INDENT 0.0
+.INDENT 3.5
+Failed to start filesystem watcher for folder yourLabel (yourID): failed to
+setup inotify handler. Please increase inotify limits, see

+Linux typically restricts the amount of watches per user (usually 8192). When
+you have more directories you need to adjust that number.
+.sp
+On many Linux distributions you can run the following to fix it:
+.INDENT 0.0
+.INDENT 3.5
+.sp
+.nf
+.ft C
+echo "fs.inotify.max_user_watches=204800" | sudo tee \-a /etc/sysctl.conf
+.ft P

+.sp
+On Arch Linux and potentially others it is preferred to write this line into a
+separate file, i.e. you should run:
+.INDENT 0.0
+.INDENT 3.5
+.sp
+.nf
+.ft C
+echo "fs.inotify.max_user_watches=204800" | sudo tee \-a /etc/sysctl.d/90\-override.conf
+.ft P
+.fi

+This only takes effect after a reboot. To adjust the limit immediately, run:
+.INDENT 0.0
+.INDENT 3.5
