+title: Docusaurus Integration
+description: AI-powered search component for Docusaurus using Upstash Search.
+---
+
+## Features
+
+- 🤖 AI-powered search results based on your documentation
+- 🎨 Modern and responsive UI
+- 🌜 Dark/Light mode support
+
+## Installation
+
+To install the package, run:
+
+```bash
+npm install @upstash/docusaurus-theme-upstash-search
+```
+
+## Configuration
+
+### Enabling the Searchbar
+
+To enable the searchbar, add the following to your docusaurus config file:
+
+```js
+export default {
+  themes: ['@upstash/docusaurus-theme-upstash-search'],
+  // ...
+  themeConfig: {
+    // ...
+    upstash: {
+      upstashSearchRestUrl: "UPSTASH_SEARCH_REST_URL",
+      upstashSearchReadOnlyRestToken: "UPSTASH_SEARCH_READ_ONLY_REST_TOKEN",
+      upstashSearchIndexName: "UPSTASH_SEARCH_INDEX_NAME",
+    },
+  },
+};
+```
+
+The default index name is `docusaurus`. You can override it by setting the `upstashSearchIndexName` option.
+
+You can fetch your URL and read only token from [Upstash Console](https://console.upstash.com/search). **Make sure to use the read only token!**
+
+If you do not have a search database yet, you can create one from [Upstash Console](https://console.upstash.com/search). Make sure to use Upstash generated embedding model.
+
+## Indexing Your Documentation
+
+### Setting Up Environment Variables
+
+To index your documentation, create a `.env` file with the following environment variables:
+
+```bash
+UPSTASH_SEARCH_REST_URL=
+UPSTASH_SEARCH_REST_TOKEN=
+UPSTASH_SEARCH_INDEX_NAME=
+DOCS_PATH=
+```
+
+You can fetch your URL and token from [Upstash Console](https://console.upstash.com/search). This time **do not use the read only token** since we are upserting data.
+
+### Running the Indexing Script
+
+After setting up your environment variables, run the indexing command:
+
+```bash
+npx index-docs-upstash
+```
+
+### Configuration Options
+
+- **DOCS_PATH**: The indexing script looks for documentation in the `docs` directory by default. You can specify a different path using the `DOCS_PATH` option.
+- **UPSTASH_SEARCH_INDEX_NAME**: The default index name is `docusaurus`. You can override it by setting the `UPSTASH_SEARCH_INDEX_NAME` option. Make sure the name you set while indexing matches with your themeConfig `upstashSearchIndexName` option.
