 **🎉 Congratulation, you've sucessfully deployed LibreChat on Hugging Face! 🤗**
+
+
+## Meilisearch Setup (Optional)
+
+To enable the search functionality in LibreChat, you'll need to deploy and configure a Meilisearch instance.  Here's how:
+
+**1. Duplicate the Meilisearch Space:**
+
+Visit this link: [https://huggingface.co/spaces/LibreChat/meilisearch](https://huggingface.co/spaces/LibreChat/meilisearch) and click "Duplicate this Space".
+
+**2. Configure the Meilisearch Space:**
+
+   *   **Visibility:** Set the visibility to "public".
+
+   *   **MEILI_MASTER_KEY:** Generate a secure 16-character master key. You can use a tool like [https://randomkeygen.com/](https://randomkeygen.com/) to generate a random key.  Set this key as the value for the `MEILI_MASTER_KEY` environment variable in the Meilisearch space.  *Important: Keep this key secure!*
+
+   *   **MEILI_ENV:** Set the `MEILI_ENV` environment variable to `production`.
+
+**3. Duplicate the Space:**
+
+Click the "Duplicate Space" button.
+
+**4. Configure LibreChat to use Meilisearch:**
+
+   *   **Edit the Dockerfile:** Go to your LibreChat space (the one you duplicated from the main LibreChat template). Navigate to "Files" -> "Dockerfile" and click "Edit".
+
+   *   **Uncomment and Modify Lines:**  Uncomment/edit the following lines in the Dockerfile.  These lines will contain `ENV SEARCH` and `ENV MEILI_*`.  Make sure to replace `<YOUR_MEILISEARCH_SPACE_URL>` with the actual URL of your Meilisearch deployment on Hugging Face Spaces. It should look something like https://username-meilisearch.hf.space/.  *Update the username to match your username!*
+
+       ```dockerfile
+       ENV SEARCH=true
+       ENV MEILI_NO_ANALYTICS=true
+       ENV MEILI_HOST=<YOUR_MEILISEARCH_SPACE_URL>
+       ```
+
+   *   **Commit Changes:** Commit your changes to the `main` branch.
+
+**5. Add the `MEILI_MASTER_KEY` Secret to LibreChat:**
+
+   *   Go to your LibreChat space's settings (the LibreChat deployment, not the Meilisearch one).
+
+   *   Click "New secret".
+
+   *   **Name:** Enter `MEILI_MASTER_KEY`.
+
+   *   **Value:**  Enter the *same* master key you used when setting up the Meilisearch space.
+
+**6. Verify the Setup:**
+
+   After LibreChat rebuilds and starts running, you should see a search option in the top left of the LibreChat interface.  If you don't see it, double-check that you've followed all the steps correctly.
