+## Installing on OSX:
+If need be, install Homebrew via https://brew.sh/ as this will allow you to
+compile new software. To do so, copy paste the instruction under 'Install
+Homebrew' into the terminal app ([Apple
+help](https://support.apple.com/guide/terminal/open-or-quit-terminal-apd5265185d-f365-44cb-8b09-71a064a42125/mac)). This might take quite a while.
+It will also ask for your password.
+
+Then run:
+```
+brew tap robertjakub/teller
+brew install --HEAD googerteller
+```
+
+To then start the noise, enter:
+```
+sudo tcpdump -nql | teller
+```
+And it should work. For the last command, it may also again ask you to enter your
+password.
+
 ## How to compile
 This will currently only work on Unix derived systems (like Linux, OSX and
 FreeBSD).
