-For other platforms, grab an archive from the release section for your platform (or nightly builds [here](https://builds.hrfee.pw/view/hrfee/jfa-go)), and extract `jfa-go` and `data` to the same directory.
-* For linux users, you can place them inside `/opt/jfa-go` and then run 
-`sudo ln -s /opt/jfa-go/jfa-go /usr/bin/jfa-go` to place it in your PATH.
+For other platforms, grab an archive from the release section for your platform (or nightly builds [here](https://builds.hrfee.pw/view/hrfee/jfa-go)), and extract the `jfa-go` executable to somewhere useful.

 Run the executable to start.
