 ## Installation
 
-This guide is a step-by-step installation guide for Alpine Linux. The instructions were verified against Alpine v3.10 standard image. You might miss additional dependencies if you use `netboot` instead.
+This guide is a step-by-step installation guide for Alpine Linux. The instructions were verified against Alpine v3.16 standard image. You might miss additional dependencies if you use `netboot` instead.
 
-It assumes that you have administrative rights, either as root or a user with [sudo permissions](https://www.linode.com/docs/tools-reference/custom-kernels-distros/install-alpine-linux-on-your-linode/#configuration). If you want to run this guide with root, ignore the `sudo` at the beginning of the lines, unless it calls a user like `sudo -Hu akkoma`; in this case, use `su -l <username> -s $SHELL -c 'command'` instead.
+As of Alpine Linux v3.16, `doas` is the preferred way of running privileged commands, which is what this guide will use.
+If you are running an earlier version, replace `doas` with `sudo` (and use `sudo -Hu akkoma` instead of `doas -u akkoma`).
+If you want to run this guide with root, ignore the `doas` at the beginning of the lines, unless it calls a user like `doas -u akkoma`; in this case, use `su -l <username> -s $SHELL -c 'command'` instead.
