 # Shared Workflows
 
 > Shared [Reusable GitHub Workflows](https://docs.github.com/en/actions/learn-github-actions/reusing-workflows#overview) for my projects
+
+## Usage
+
+To use the shared workflow, you need to use the `uses` keyword when referring to a `job` in the workflow. As an example: `jobs.<job_id>.uses`.
+
+Here is an example workflow file:
+
+```yaml
+name: Publish NPM Package
+
+on:
+  push:
+    branches:
+      - main
+  workflow_dispatch:
+
+jobs:
+  npm-publish:
+    uses: devshareacademy/shared-workflows/.github/workflows/publish-package.yml@main
+    secrets:
+      npm_token: ${{ secrets.NPM_TOKEN }}
+      gh_token: ${{ secrets.GH_TOKEN }}
+```
+
+*Note:* For more information on calling a reusable workflow, please see the following: [Calling Reusable Workflows](https://docs.github.com/en/actions/learn-github-actions/reusing-workflows#calling-a-reusable-workflow).
