+    cd yay
+    makepkg -si
+fi
+#+end_src

+*** Package Installation
+remove all packages not in ~pkg-list.txt~
+#+begin_src shell :tangle update.sh
+# Get list of installed packages
+INSTALLED_PACKAGES=$(yay -Qqe)
+
+# Read the list of packages to keep from the file
+KEEP_LIST=$(cat "pkg-list.txt")
+
+# Loop through installed packages
+for PACKAGE in $INSTALLED_PACKAGES; do
+    # Check if the package is not in the keep list
+    if ! echo "$KEEP_LIST" | grep -q "^$PACKAGE$"; then
+        echo "Removing package: $PACKAGE"

+#+begin_src shell :tangle update.sh
+systemd_service="NetworkManager"
+if ! systemctl is-enabled --quiet "$systemd_service"; then
