 ## Building
 Simply download the contents of the "src" folder  and pack the contents into a .zip file. Then, rename the file to .xpi and drag into the browser.
 
+On Unix systems (or Windows 10, with [WSL](https://docs.microsoft.com/en-us/windows/wsl/about)) you can optionally run `build.sh` instead. Running this as-is will produce a .xpi file ending in `-dev`, and if run from the command line and appending a number (e.g. `./build.sh 2`) will append that number to the filename instead.
