+Downloading and running Doc Detective is straightforward. Follow these steps to install Doc Detective and run your first test:
+
+1. Install prerequisites:
+
+    - [Node.js](https://nodejs.org/) v18.20.0 or later
+
+2. In a terminal, install Doc Detective globally:
+
+    <CodeBlock language="bash" title="Install Doc Detective">
+      npm i -g doc-detective
+    </CodeBlock>
+    {/* step runShell: "npm i -g doc-detective" */}
+
+    :::note
+
+    If you're working in a local copy of the `doc-detective` repository, you need to run `npm i` to install local dependencies.
+
+    :::
+
+3.  Save this file to your current directory as _sample.spec.json_:
+
+    <CodeBlock language="json" title="sample.spec.json">
+      {JSON.stringify(spec, null, 2)}
+    </CodeBlock>
+
+4. Run a test, pointing to the file you just created:
+
+    <CodeBlock language="bash" title="Run test">
+      npx doc-detective --input sample.spec.json
+    </CodeBlock>
+    {/* step runShell:
+    command: "npx doc-detective --input sample.spec.json"
+    workingDirectory: "." */}
+
+
+Congratulations! You've run your first test with Doc Detective. :tada:
+
+You should see output in the terminal indicating the progress and results of the test. Results are also saved in a `testResults-<timestamp>.json` file in the current directory (configurable with the `--output` option), and this test saves a screenshot to example.png:
