+<Info>
+  **Prerequisite** You should have installed Node.js (version 18.10.0 or
+  higher).
+</Info>
+
+Step 1. Install Mintlify on your OS:
+
+<CodeGroup>
+
+```bash npm
+npm i -g mintlify
+```
+
+```bash yarn
+yarn global add mintlify
+```
+
+</CodeGroup>
+
+Step 2. Go to the `docs/` directory (where you can find `mint.json`) and run the following command:
+
+```bash
+mintlify dev
+```
+
+The documentation website is now available at `http://localhost:3000`.
+
+### Custom Ports
+
+Mintlify uses port 3000 by default. You can use the `--port` flag to customize the port Mintlify runs on. For example, use this command to run in port 3333:
+
+```bash
+mintlify dev --port 3333
+```
+
+You will see an error like this if you try to run Mintlify in a port that's already taken:
+
+```md
+Error: listen EADDRINUSE: address already in use :::3000
+```
+
+## Mintlify Versions
+
+Each CLI is linked to a specific version of Mintlify. Please update the CLI if your local website looks different than production.
+
+<CodeGroup>
+
+```bash npm
+npm i -g mintlify@latest
+```
+
+```bash yarn
+yarn global upgrade mintlify
+```
+
+</CodeGroup>
