-PMG is a security-focused wrapper for package managers that helps detect and prevent the installation of potentially malicious packages.
+## TL;DR
 
+Set up `pmg` to protect you development environment:
+
+```
+echo "alias npm='pmg npm'" >> ~/.zshrc
+echo "alias pnpm='pmg pnpm'" >> ~/.zshrc
+source ~/.zshrc
+```
+
