+# Publishing Guide for Maintainers
+
+This document describes how to publish the `@hypercerts-org/lexicon`
+package to npm using GitHub Actions workflows. All publishing
+workflows are manually triggered to give you full control over when
+releases are made.
+
+## Prerequisites
+
+Before publishing, ensure you have:
+
+1. **GitHub Secrets configured:**
+   - `GH_PA_TOKEN`: GitHub Personal Access Token with permissions for
+     releases
+   - `NPM_TOKEN`: npm access token with publish permissions for
+     `@hypercerts-org` scope
+
+2. **GitHub Environments configured:**
+   - `test`: For the build-and-test job
+   - `staging`: For the semantic-release job
+
+## Publishing a Release
+
+To publish a new release to npm:
+
+1. **Navigate to GitHub Actions:**
+   - Go to the repository on GitHub
+   - Click on the "Actions" tab
+
+2. **Select the workflow:**
+   - Choose "Build and release" from the workflow list
+
+3. **Run the workflow:**
+   - Click "Run workflow"
+   - Select the branch (typically `main`)
+   - Click "Run workflow" to start
+
+4. **What happens:**
+   - The workflow runs linting and regenerates TypeScript types
+   - If successful, semantic-release analyzes your commits
+   - If there are version-worthy changes, it:
+     - Determines the new version based on
+       [Conventional Commits](https://www.conventionalcommits.org/)
+     - Updates `CHANGELOG.md`
+     - Creates a GitHub release
+     - Publishes to npm with the new version
+
+## Publishing a Prerelease
+
+To publish a beta/prerelease version:
+
+1. **Navigate to GitHub Actions:**
+   - Go to the "Actions" tab
+
+2. **Select the prerelease workflow:**
+   - Choose "Build and release - staging"
+
+3. **Run the workflow:**
+   - Click "Run workflow"
+   - Select the branch (typically `develop` or a feature branch)
+   - Click "Run workflow"
+
+4. **What happens:**
+   - Same process as above, but publishes with a `beta` tag
+   - Version format: `1.2.3-beta.1`, `1.2.3-beta.2`, etc.
+
+## Validating Releases (PRs)
+
+When you open a pull request, the "Build and release - staging"
+workflow automatically runs in dry-run mode to:
+
+- Validate that the code builds successfully
+- Check that types regenerate correctly
+- Show what version would be released (without actually publishing)
+
+This helps catch issues before merging.
+
+## Version Management
+
+Versions are automatically determined by semantic-release based on
+commit messages:
+
+- `feat:` → minor version bump (1.0.0 → 1.1.0)
+- `fix:` → patch version bump (1.0.0 → 1.0.1)
+- `BREAKING CHANGE:` or `!` → major version bump (1.0.0 → 2.0.0)
+
+The `prepublishOnly` script ensures types are regenerated before
+publishing, so the published package always includes the latest
+generated TypeScript types.
