+### TypeScript
+
+This package includes TypeScript type definitions:
+
+```ts
+import shallowequal, { Comparator } from "shallowequal";
+
+const customCompare: Comparator = (a, b, key) => {
+  // Custom comparison logic

 ## Credit
 
 Code for `shallowEqual` originated from https://github.com/gaearon/react-pure-render/ and has since been refactored to have the exact same API as `lodash.isEqualWith` (as of `v4.17.4`).
 
 ## Development
 
-- `node.js` and `npm`. See: https://github.com/creationix/nvm#installation
-- `yarn`. See: https://yarnpkg.com/en/docs/install
-- `npm` dependencies. Run: `yarn install`
+Prerequisites:
+- [Node.js](https://nodejs.org/) (v18+)
+- [pnpm](https://pnpm.io/)
+
+### Setup
+
+```sh
+pnpm install
+```
+
+### Commands
 
-### Chores
+Using Make:
 
-- Lint: `yarn lint`
-- Test: `yarn test`
-- Pretty: `yarn pretty`
-- Prepare: `yarn prepare`
+```sh
+make install    # Install dependencies
+make build      # Build the project
+make test       # Run tests
+make test-watch # Run tests in watch mode
+make lint       # Run linter
+make typecheck  # Run type checking
+make clean      # Clean build artifacts
+make ci         # Run full CI pipeline
+```
+
+Or using pnpm directly:
+
+```sh
+pnpm install    # Install dependencies
+pnpm build      # Build the project
+pnpm test       # Run tests
+pnpm test:watch # Run tests in watch mode
+pnpm lint       # Run linter
+pnpm typecheck  # Run type checking
+```
