+# Setup sudoers file
+echo "%wheel ALL=(ALL) ALL" > /etc/sudoers.d/wheel
+
+# Add default username and password
+username=johndoe
+useradd -m -G wheel -s /bin/bash $username
+passwd $username
+
+exit
+```
+
+Now run:
+
+```pwsh
+wsl.exe --terminate Arch
+
+.\Arch.exe config --default-user johndoe
+
+wsl.exe -d Arch
+```
+
+Initialize keyring for use with `pacman`
