-## Extra
+## Notes
 - `empty` contains only 2 files:
   - `/ssh` _(The self-compiled OpenSSH client)_
   - `/etc/passwd` with only 1 line: `root:x:0:0:root:/:/ssh` _(ssh needs to know it's user)_
   - __No__ other files or directories are present.<br>This implies thay you will have to __launch ssh as `/ssh` instead of `ssh` in `empty`__
 - `busybox` contains the same self-compiled OpenSSH client.
+- Arch Linux has no official arm64 image. The image for arm64 is using `menci/archlinuxarm` as a base image.
 - There is also a `builder` that was used to compile OpenSSH for `empty` and `busybox`. It cannot be used directly and should be ignored
 - For now consider all images _(certainly `empty` and `busybox`)_ as experimental. Report all issues.
