+# npm Publishing Setup
+
+This repository now supports publishing to both JSR (JavaScript Registry) and npm. Here's what was added:
+
+## Files Added/Modified
+
+### Build Scripts
+- `scripts/build_npm.ts` - Primary build script using dnt (Deno Node Transform)
+- `scripts/build_npm_manual.ts` - Fallback manual build script for network issues
+
+### GitHub Actions
+- `.github/workflows/publish.yml` - Updated to publish to both JSR and npm
+- `.github/workflows/npm-build-test.yml` - Tests npm build on PRs
+
+### Configuration
+- `deno.jsonc` - Added npm build tasks
+- `.gitignore` - Added npm/ directory to ignore build artifacts
+
+### Documentation
+- `README.md` - Updated with npm installation instructions and dual import examples
+
+## How It Works
+
+1. **Primary Method (dnt)**: Uses Deno Node Transform to automatically convert Deno TypeScript code to npm-compatible JavaScript packages with proper Node.js shims.
+
+2. **Fallback Method (manual)**: Performs basic TypeScript-to-JavaScript conversion by processing files directly. This is used when network issues prevent dnt from downloading dependencies.
+
+3. **Dual Publishing**: GitHub Actions workflow publishes to both JSR and npm when tags are pushed.
+
+## Package Structure
+
+The npm package will include:
+- ESM format JavaScript files  
+- TypeScript definition files
+- All exports from `deno.jsonc` mapped to npm package exports
+- Support for both import and require (ESM/CommonJS)
+- Node.js compatibility shims for Deno APIs
+
+## For Repository Owner
+
+To enable npm publishing:
+
+1. Create npm account at https://www.npmjs.com/signup
+2. Generate automation token at https://www.npmjs.com/settings/tokens  
+3. Add token as `NPM_TOKEN` secret in repository settings
+4. Push a git tag to trigger publishing to both JSR and npm
+
+The package will be published as `@cosense/std` on npm (same as JSR name).
