 Unit and E2E tests are ran together via [Vitest workspaces](https://vitest.dev/guide/#workspaces-support).
 
 If you want to manually test a change, you can modify the demo project for your test, but please don't leave those changes committed once you open a PR.
+
+## Templates
+
+Each directory inside `templates/` is it's own standalone project. Simply `cd` into the directory you're updating, install dependencies with `npm` (NOT `pnpm`), and run the relevant commands
+
+```sh
+cd templates/vue
+npm i
+npm run dev
+npm run build
+```
+
+Note that templates are hardcoded to a specific version of `wxt` from NPM, they do not use the local version. PR checks will test your changes against the templates, but if you want to manually do it, update the package.json dependency:
+
+```diff
+  "devDependencies": {
+    "typescript": "^5.3.2",
+    "vite-plugin-solid": "^2.7.0",
+-   "wxt": "^0.8.0"
++   "wxt": "../.."
+  }
+```
+
+Then run `npm i` again.
+
+### Adding Templates
+
+To add a template, copy the vanilla template and give it a new name.
+
+```sh
+cp -r templates/vailla templates/<new-template-name>
+```
+
+That's it. Once your template is merged, it will be available inside `wxt init` immediately. You don't need to release a new version of WXT to release a new template.

-## UI
-
-WXT provides a utility function, `createContentScriptUi` to simplify mounting a UI from a content script. Internally, it uses the `ShadowRoot` API to isolate your CSS from the webpages.
-
-`createContentScriptUi` requires a `ContentScriptContext` so that when the context is invalidated, the UI is automatically removed from the webpage.
-
-:::details When to use `createContentScriptUi`
-You should only use `createContentScriptUi` if you want your UI's styles isolated from the webpages. If you want to create a more "integrated" UI that uses the page's styles, you can just use the regular JS API's to append your UI to the page.
-
-```ts
-const ui = document.createElement('div');
-const anchor = document.querySelector('#anchor-selector');
-anchor.append(ui);
-```
-
-:::
-
-### Usage
-
-To use `createContentScriptUi`, follow these steps:
-
-1. Import your CSS file at the top of your content script
-2. Set `cssInjectionMode: "ui"` inside `defineContentScript`
-3. Call `createContentScriptUi`
-4. Call `ui.mount()` to add the UI to the webpage
-
-Here's a basic example:
-
-```ts
-// entrypoints/ui.content/index.ts
-import './style.css';
-
-export default defineContentScript({
-  // ...
-  cssInjectionMode: 'ui',
-
-  async main(ctx) {
-    const ui = await createContentScriptUi(ctx, {
-      name: 'example-ui',
-      type: 'inline',
-      anchor: '#some-element',
-      append: 'after',
-      mount(container) {
-        // Mount UI inside `container`...
-      },
-    });
-
-    // Yoy must call `mount` to add the UI to the page.
-    ui.mount();
-  },
-});
-```
-
-If you're using a frontend framework, you'll also need to include an `onRemoved` callback:
-
-:::code-group
-
-```ts [Vue]
-import { createApp } from 'vue';
-
-createContentScriptUi(ctx, {
-  // ...
-  mount(container) {
-    // Create a new app and mount it inside the container
-    const app = createApp(...);
-    app.mount(container);
-    return app;
-  },
-  onRemove(app) {
-    // When the UI is removed from the DOM, call unmount to stop the app
-    app.unmount();
-  },
-});
-```
-
-```ts [React]
-import ReactDOM from 'react-dom/client';

-    const root = ReactDOM.createRoot(container);
-    root.render(...);
-    return root;
-  },
-  onRemove(root) {
-    // When the UI is removed from the DOM, call unmount to stop the app

-  onRemove(app) {

-  },
-});

-
-:::
-
-### `anchor`
-
-The anchor dictates where the UI will be mounted.
-
-### `append`
-
-Customize where the UI get's appended to the DOM, relative to the `anchor` element.
-
-### `type`
-
-There are 3 types of UI's you can mount.
-
-- `inline`: Shows up inline based on the `anchor` and `append` options
-- `overlay`: Shows up inline, but styled to be 0px by 0px, with overflow visible. This causes the UI to overlay on top of the webpage's content
-- `modal`: A fullscreen overlay that covers the entire screen, regardless of where it's anchored.
-
-> TODO: Add visualization of the different UI types.
-
-### Overlay `alignment`
-
-Because the overlay UI type results in a 0px by 0px container being added to the webpage, the `alignment` option allows you to configure which corner of your UI is aligned with the 0x0 element.
-
-> TODO: Add visualization of the different alignments.

+
+## ShadowRoot
+
+Often in web extensions, you don't want your content script's CSS effecting the page, or vise-versa. The [`ShadowRoot` API](https://developer.mozilla.org/en-US/docs/Web/API/ShadowRoot) is ideal for this. It isolates an element's style from the page's style.
+
+WXT provides a helper function, [`createContentScriptUi`](/api/wxt/client/functions/createContentScriptUi), that abstracts all the `ShadowRoot` setup away, making it easy to create UIs with isolated styles.
+
+To use `createContentScriptUi`, follow these steps:
+
+1. Import your CSS file at the top of your content script
+2. Set `cssInjectionMode: "ui"` inside `defineContentScript`
+3. Define your UI with `createContentScriptUi()`
+4. Mount the UI so it is visible to users
+
+```ts
+// 1. Import the style
+import './style.css';
+
+export default defineContentScript({
+  // 2. Set cssInjectionMode
+  cssInjectionMode: 'ui',
+
+  async main(ctx) {
+    // 3. Define your UI
+    const ui = await createContentScriptUi(ctx, {
+      name: 'example-ui',
+      anchor: '#anchor',
+      type: 'inline',
+      mount(container) {
+        // Define how your UI will be mounted inside the container
+        const app = document.createElement('p');
+        app.textContent = 'Hello world!';
+        container.append(app);
+      },
+    });
+
+    // 4. Mount the UI
+    ui.mount();
+  },
+});
+```
+
+> `createContentScriptUi` will automatically remove the UI from the page when the content script is invalidated.
+
+See the [API Reference](/api/wxt/client/functions/createContentScriptUi) for the complete list of options.
+
+:::info TailwindCSS
+`createContentScriptUi` supports TailwindCSS out of the box! When importing the styles, just import the main CSS file containing the `@tailwind` directives, and everything will just work :+1:.
+:::
+
+When using a frontend framework for your UI, you'll need to unmount the app when the UI is removed. When defining the UI, return an app reference from the `mount` option and pass in a custom `onRemoved` option:
+
+:::code-group
+
+```ts [Vue]
+import { createApp } from 'vue';
+
+const ui = createContentScriptUi(ctx, {
+  // ...
+  mount(container) {
+    const app = createApp(App);
+    app.mount(container);
+    return app;
+  },
+  onRemove(app) {
+    app.unmount();
+  },
+});
+```
+
+```tsx [React]
+import ReactDOM from 'react-dom/client';
+
+const ui = createContentScriptUi(ctx, {
+  // ...
+  mount(container) {
+    const root = ReactDOM.createRoot(container);
+    root.render(...);
+    return root;
+  },
+  onRemove(root) {
+    root.unmount();
+  },
+});
+```
+
+```ts [Svelte]
+import App from './App.svelte';
+
+const ui = createContentScriptUi(ctx, {
+  // ...
+  mount(container) {
+    return new App({ target: container });
+  },
+  onRemove(app) {
+    app.$destry();
+  },
+});
+```
+
+```tsx [Solid]
+import { render } from 'solid-js/web';
+
+const ui = createContentScriptUi(ctx, {
+  // ...
+  mount(container) {
+    return render(() => ..., container);
+  },
+  onRemove(unmount) {
+    unmount();
+  },
+});
+```
+
+:::
+
+:::warning
+The `mount(container)` and `onRemove(app)` options passed into `createContentScriptUi` **_are different from_** the `ui.mount()` and `ui.remove()` functions available on the returned UI object.
+
+You don't need to pass anything into `ui.mount()` and `ui.remove()` because **_you already defined how and where the UI will be mounted_** in the options passed into `createContentScriptUi`.
+:::
+
+## IFrame
+
+If you don't need to run your UI in the same frame as the content script, you can use an IFrame to host your UI instead. Since an IFrame just hosts an HTML page, **_HMR is supported_**.
+
+WXT provides a helper function, [`createContentScriptIframe`](/api/wxt/client/functions/createContentScriptUi), which simplifies setting up the IFrame.
+
+1. Create an HTML page that will be loaded into your IFrame
+   ```html
+   <!-- entrypoints/example-iframe.html -->
+   <!doctype html>
+   <html lang="en">
+     <head>
+       <meta charset="UTF-8" />
+       <meta name="viewport" content="width=device-width, initial-scale=1.0" />
+       <title>Your Content Script IFrame</title>
+     </head>
+     <body>
+       <!-- ... -->
+     </body>
+   </html>
+   ```
+1. Add the page to the manifest's `web_accessible_resouces`
+   ```ts
+   // wxt.config.ts
+   export default defineConfig({
+     manifest: {
+       web_accessible_resources: [
+         {
+           resources: ['example-iframe.html'],
+           matches: [...],
+         },
+       ],
+     },
+   });
+   ```
+1. Create and mount the IFrame
+
+   ```ts
+   export default defineContentScript({
+     // ...
+     async main(ctx) {
+       // Define the UI
+       const ui = await createContentScriptIframe(ctx, {
+         page: '/example-iframe.html',
+         anchor: '#anchor',
+         type: 'inline',
+       });
+
+       // Add styles to the iframe like width
+       ui.iframe.width = 123;
+
+       // Show UI to user
+       ui.mount();
+     },
+   });
+   ```
+
+See the [API Reference](/api/wxt/client/functions/createContentScriptUi) for the complete list of options.

-[[toc]]
+## Unit tests
 
-## Fake Browser
+If you're using auto-imports (enabled by default), [Vitest](https://vitest.dev/) is the only testing framework that supports them.
 
-The `wxt/fake-browser` package includes an in-memory implementation of the `browser` variable you can use for testing. WXT simply re-exports the `fakeBrowser` variable from [`@webext-core/fake-browser`](https://webext-core.aklinker1.io/guide/fake-browser/).
+If you want to use a different testing library/framework (like Jest, mocha, node:test, etc), you can keep using it, but you have two options:
 
-Here's an example test using Vitest:
+1. Switch to Vitest (recommended)
+2. Configure the testing library manually
+   - Disable auto-imports by setting `imports: false` in your `wxt.config.ts` file
+   - Manually add globals normally provided by WXT (like `__BROWSER__`) that you consume to the global scope before accessing them (`globalThis.__BROWSER__ = "chrome"`)

-## Handling Auto-imports
-
-By default, WXT uses auto-imports. For tests, this can cause issues if your test environment is not setup to handle them correctly.
-
-:::warning 🚧 Testing utils are not implemented yet!
-Eventually, WXT will provide utilities for setting up these auto-imports. For now, you'll need to set them up manually.
-:::
-
-Not all testing frameworks can handle auto-imports. If your framework or setup is not listed below, it may be easiest to disable auto-imports.
-
-To setup auto-imports manually, use [`unplugin-auto-import`](https://www.npmjs.com/package/unplugin-auto-import). It uses the same tool, `unimport`, as WXT and will result in compatiple auto-imports. `unplugin-auto-import` supports lots of different tools (vite, webpack, esbuild, rollup, etc). You can try and integrate it into your build process.
-
-### Vitest (Recommended)
-
-Vitest is easy, simply add `uplugin-auto-import` to your project.
-
 ```ts
-// vitest.config.ts
-import autoImports from 'unplugin-auto-import/vite';
+// <root>/vitest.config.ts
+import { defineConfig } from 'vitest/config';
+import { WxtVitest } from 'wxt/testing';
 
 export default defineConfig({
-  plugins: [
-    autoImports({
-      imports: [{ name: 'defineConfig', from: 'wxt' }],
-      presets: [{ package: 'wxt/client' }, { package: 'wxt/browser' }],
-      dirs: ['components', 'composables', 'hooks', 'utils'],
-    }),
-  ],
+  plugins: [WxtVitest()],
+  test: {
+    server: {
+      deps: {
+        // Add any dependencies that import webextension-polyfill here, otherwise tests will attempt to import the real polyfill, breaking the
+        // TODO: Auto-detect these dependencies inside `WxtVitest` so maintaining this list manually isn't necessary
+        inline: [...],
+      },
+    },
+  },
 });
 ```
 
-### Jest
+And that's it. You're ready to start writing tests.
 
-Don't use jest and auto-imports. You could try and configure jest to be transpiled by one of `unplugin-auto-import`'s supported built tools, but I don't know of a way to configure this. See [unplugin/unplugin-auto-import#33](https://github.com/unplugin/unplugin-auto-import/issues/33) if you want to try and set it up.
+### Writing Tests
 
-I would recommend disabling auto-imports or migrating to Vitest if you want to use auto-imports.
+Here's a very basic test, written with a few different testing libraries, with a few different approaches for mocking the `browser` global.
 
-### Mocha
+:::code-group

+- Playwright provides an API to get your extension ID after it has been installed. [See their docs](https://playwright.dev/docs/chrome-extensions#testing).
+- Puppeteer requires you know the ID before installing the extension, so you can hard code it into the URLs you open. Follow [Chrome's guide](https://developer.chrome.com/docs/extensions/mv3/manifest/key/) to setup a consistent runtime id.
+
+:::info
+You cannot test popups in their normal popup window, you have to open them in a tab.
