+## Getting Started
+
+When you start Athena OS WSL, it is a best practice to use the fastest mirrors for your location and update all the packages. To do this, run:
+```
+mirrorxx
+sudo rate-mirrors --concurrency 40 --allow-root --disable-comments --save /etc/pacman.d/chaotic-mirrorlist chaotic-aur
+init-keys
+sudo pacman -Syyu
+```
+:::note
+If you get messages like `WARNING: failed to rate http(s) download (https://mirror.theash.xyz/arch/extra/os/x86_64/extra.db): HTTP Error 403: Forbidden`, you can ignore them.
