 ## What does **nypm** do?
 
-✅ Supports **npm, yarn and pnpm** out of the box with a unified API
+✅ Supports **npm, yarn, pnpm and bun** out of the box with a unified API
 
 ✅ Provides an **API interface** to interact with package managers
 
 ✅ **Autodetects** project's package manager using package.json and known lockfiles
 
-✅ **Auto-installs and use exactly expected version** of package manager using [nodejs/corepack](https://github.com/nodejs/corepack)
+✅ **Auto-installs and use exactly expected version** of supported package managers using [nodejs/corepack](https://github.com/nodejs/corepack)
 
 ✅ **Minimal** implementation
 
 nypm, detects package manager type and version and converts command into package manager CLI arguments. It then uses corepack to execute package manager's command (and download it if necessary).
