+# GitHub Action for Validating Documentation Links
+
+This action ensures that internal links in `.mdx` files in the `/docs/` directory are valid. It runs on every pull request that includes changes to these files.
+
+The action is triggered by the workflow defined in `.github/workflows/validate-docs-links.yml`.
+
+## Usage
+
+This action is written in TypeScript and compiled locally before being pushed to GitHub.
+
+To make changes:
+
+- Edit the `src/index.ts` file.
+- Navigate to the script folder `cd .github/actions/validate-docs-links`
+- Run `npm install` to install dependencies.
+- Run `npm run build` to compile code. This will create an updated `lib/index.js`.
+- Commit and push changes to GitHub.
