 ## Example bash helper functions
 
-I have the following in my `~/.bash_profile` in WSL. Note that there is a
-line in start_gpgbridge that must be uncommented for WSL2.
+Copy the script below to somewhere accessible from WSL, make it executable
+(`chmod +x path/to/gpgbridge_helper.sh`).
+
+Then add `source path/to/gpgbridge_helper.sh` to your `~/.bash_profile`,
+`~/.bashrc` or `~/.zshrc`. If you are running this from WSL 2 you should also
+add `WSL2=true` before the `source` line.
+
+Make sure to edit the variables in the start of the script according to your
+setup.
