 # @dotgithub/core
 
-Core library for DotGitHub: type-safe constructs and workflow generation utilities.
+Type-safe TypeScript library for defining and generating GitHub Actions workflows using DotGitHub constructs.
+
+## What this package is
+
+`@dotgithub/core` is the programmatic engine behind DotGitHub. It provides:
+
+- strongly typed workflow models
+- construct primitives for jobs/workflows/shared workflows
+- generation/synthesis helpers for writing `.github/workflows/*.yml`
+
+If you want to author reusable CI/CD logic in TypeScript (instead of hand-writing YAML), this is the package you use.
 
 ## Install
 
 ```bash
 npm install @dotgithub/core
 ```
 
+## Quick example
+
+```ts
+import { createWorkflow } from '@dotgithub/core';
+
+const workflow = createWorkflow({
+  on: {
+    push: { branches: ['main'] },
+  },
+  jobs: {
+    test: {
+      'runs-on': 'ubuntu-latest',
+      steps: [
+        { uses: 'actions/checkout@v4' },
+        { run: 'npm ci' },
+        { run: 'npm test' },
+      ],
+    },
+  },
+});
+
+// synthesize with your DotGitHub pipeline
+```
+
+## When to use `@dotgithub/core` vs `@dotgithub/cli`
+
+- Use **`@dotgithub/core`** for library/SDK style usage in code.
+- Use **`@dotgithub/cli`** when you want command-driven setup and synthesis.
