-# `@gitbook/cache-do`
-
-Cache backend, powered by Cloudflare Durable Objects. The cache is optimized for GitBook use-cases.
-
-### Performances
-
-The cache backend is optimized for performances by being distributed and accessible close to the worker locations that are reading it.
-
-### Geo-distribution
-
-To achieve a good balance between **performances** and **consistency**, cache objects are distributed over 7 locations, representing continents.
-
-It makes it possible to purge all 7 locations in one go and achieve fast consistency.
-
-### Concepts
-
-**Cache tag**: unique tag in the cache environment. A cache tag groups multiple keys that should be purged together in one operation.
-Cache tags should not contain a large set of unique keys. Exceeding thousands could lead to performances or reliability issues.
-
-**Cache key**: unique key in the cache environment. Each key should be assigned to a `tag`.
-
-**Location**: cache is distributed over 7 unique locations, one for each continent.

+
+Embed the GitBook Docs Assistant in your product or website.
+
+# Usage
+
+## As a script from your docs site
+
+All GitBook docs site includes a script to easily embed the docs assistant as a widget on your website.
+
+The script is served at `https://docs.company.com/~gitbook/embed/script.js`.
+
+You can find the embed script from your docs site settings, or you can copy the following and replace the `docs.company.com` by your docs site hostname.
+
+```html
+<script src="https://docs.company.com/~gitbook/embed/script.js"></script>
+<script>
+window.GitBook('show');
+</script>
+```
+
+## As a package from NPM
+
+Install the package: `npm install @gitbook/embed` and import it in your web application:
+
+```tsx
+import { createGitBook } from '@gitbook/embed';
+
+const gitbook = createGitBook({
+    siteURL: 'https://docs.company.com'
+});
+
+const iframe = document.createElement('iframe');
+iframe.src = gitbook.getFrameURL();
+
+const frame = gitbook.createFrame(iframe);
+```
+
+## As React components
+
+After installing the NPM package, you can import prebuilt React components:
+
+```tsx
+import { GitBookProvider, GitBookAssistantFrame } from '@gitbook/embed/react';
+
+<GitBookProvider siteURL="https://docs.company.com">
+    <GitBookAssistantFrame />
+</GitBookProvider>
+```
