 If you want to add a new feature, please create an issue or discussion first so we can decide if the feature is inline with the vision for WXT.
 
+## WXT's Vision
+
+WXT is two things:
+
+1. A build tool
+2. A set of runtime utilities
+
+The long term goal of WXT is provide an opinionated build tool that keeps WXT projects standard, while providing light-weight runtime utils that simplify a lot of the boilerplate/overhead when setting up a new extension.
+
+I also want to provide a way for developers to use either one of those two things independently, and not require them to use both. This is why all of WXT's runtime utils are shipped as their own NPM packages, most of them not bundled inside the core `wxt` package. If you just want to use the packages, they're availalbe, and if you just want to use WXT's built tool, you don't have to import any of WXT's utilities, you can use your own.
+
+> The few runtime utils shipped inside WXT are things that should be used by 90% of extensions. That said, they're also legacy utils left in from before I started creating separate NPM packages, and in the future, they may be removed from the core package.
+
 ## Conventional Commits
 
 This project uses [Conventional Commit format](https://www.conventionalcommits.org/en/v1.0.0/) to automatically generate a changelog and better understand the changes in the project
@@ -20,6 +33,19 @@ Here are some examples of conventional commit messages:
 
 The title of your pull request should follow the [conventional commit format](#conventional-commits). When a pull request is merged to the main branch, all changes are going to be squashed into a single commit. The message of this commit will be the title of the pull request. And for every release, the commit messages are used to generate the changelog.
 
+## Breaking Changes Policy
+
+A quick word on WXT's breaking changes policy. I am willing to make breaking changes, but they have to be for a good enough reason - they have to make WXT better as a whole, they can't be based on one opinion.
+
+Breaking changes also require a major release. Major releases have happened once or twice a year, so after you merge your PR, you'll have to wait a little bit before it is released.
+
+To make a breaking change:
+
+1. Make sure you're PR is targeting the `major` branch
+2. Add `!` after the conventional commit type (`fix!: ...`, `feat!: ...`, `chore!: ...`, etc) to indicate that it is a breaking change
+3. At the top of the PR, provide documentation that will inform developers about the breaking change, why it was done, and how to migrate their extension so nothing breaks.
+   - This documentation will be put ["Upgrading WXT"](https://wxt.dev/guide/resources/upgrading.html) page in the docs, read through previous breaking change docs for an idea of what is required.

+## Be picky about new features and packages
+
+We are responsible for maintaining them and fixing related bugs after the PR is merged. The community can always release their own WXT modules or packages, not everything needs to be built into WXT.
+
+## Prefer standards over customization
+
+Don't merge PRs that just add another way to do something, like [this one](https://github.com/wxt-dev/wxt/pull/2053#issuecomment-3857010196).
+
+WXT is opinionated, if you have questions about what is WXT's opinion or we need to create a new one, create an issue and @ me to discuss.
+
+## PRs should be small and targeted
+
+A PR should make one change. They should not make any unrelated changes outside of accomplishing the one thing. This makes PRs easier to review and they get merged more quickly - a win-win for everyone.
+
+## `@wxt-dev/*` packages are separate
+
+We can't make changes to these packages assuming people are using them only with WXT. For example, I almost missed [this PR](https://github.com/wxt-dev/wxt/pull/2049#issuecomment-3861251599).
+
+I want these packages to be usable on their own so if people don't like WXT's build tool, they can still use our other awesome packages.
+
+## Minimize dependencies
+
+I don't like how heavy lots of frameworks are. It's unavoidable to a certain extent, but if you can do something without another dependency, try to.
+
+If you need a dependency, look for one with zero dependencies and that's respectable.
+
+## Look at milestones
+
+I've organized WXT's long term plans into [milestones](https://github.com/wxt-dev/wxt/milestones), check those out to get an idea of my priorities for some of the larger features.
+
+## Require tests
+
+If someone opens a PR to fix a bug but doesn't include tests, don't merge the PR. Tests are required to prevent regressions and maintain a codebase long term.
+
+## Ask for reproductions for bugs
+
+You don't need to triage bugs if someone doesn't give you enough information. You can always ask for a repo with a reproduction or wait for more details.
+
+If there's not an easy way to reproduce a bug, you're wasting your time triaging it. Just be mindful of your own time!
+
+Here's an example of how to ask for a reproduction: <https://github.com/wxt-dev/wxt/issues/2064#issuecomment-3862579110>. You could be more blunt than this.
+
+## Add yourself as a code owner
+
+If you want to be responsible for a specific package or directory, add yourself to the [`.github/CODEOWNERS`](https://github.com/wxt-dev/wxt/blob/main/.github/CODEOWNERS) file to get added as a reviewer to PRs automatically. You can also add yourself to the default list to be added as a reviewer on all PRs.

 However for MV2, `injectScript` has to `fetch` the script's text content and create an inline `<script>` block. This means for MV2, your script is injected asynchronously and it will not be evaluated at the same time as your content script's `run_at`.
 :::
 
+The `script` element can be modified just before it is added to the DOM by using the `modifyScript` option. This can be used to e.g. modify `script.async`/`script.defer`, add event listeners to the element, or pass data to the script via `script.dataset`. An example:
+
+```ts
+// entrypoints/example.content.ts
+export default defineContentScript({
+  matches: ['*://*/*'],
+  async main() {
+    await injectScript('/example-main-world.js', {

+export default defineUnlistedScript(() => {
+  console.log(document.currentScript?.dataset['greeting']);
+});
+```
+
+`injectScript` returns the created script element. It can be used to e.g. send messages to the script in the form of custom events. The script can add an event listener for them via `document.currentScript`. An example of bidirectional communication:
+
+```ts
+// entrypoints/example.content.ts
+export default defineContentScript({

+  async main() {
+    const { script } = await injectScript('/example-main-world.js', {

 ## Mounting UI to dynamic element
 
 In many cases, you may need to mount a UI to a DOM element that does not exist at the time the web page is initially loaded. To handle this, use the `autoMount` API to automatically mount the UI when the target element appears dynamically and unmount it when the element disappears. In WXT, the `anchor` option is used to target the element, enabling automatic mounting and unmounting based on its appearance and removal.

+## Entrypoint Limitations
+
+Because WXT imports your entrypoint files into a NodeJS, non-extension environment, the `chrome`/`browser` variables provided to extensions by the browser **will not be available**.
+
+To prevent some basic errors, WXT polyfills these globals with the same in-memory, fake implementation it uses for testing: [`@webext-core/fake-browser`](https://webext-core.aklinker1.io/fake-browser/installation/). However, not all the APIs have been implemented.
+
+So it is extremely important to NEVER use `browser.*` extension APIs outside the main function of any JS/TS entrypoints (background, content scripts, and unlisted scripts). If you do, you'll see an error like this:
+
+```plaintext
+✖ Command failed after 440 ms
+
+ ERROR  Browser.action.onClicked.addListener not implemented.

 WXT's `browser` no longer uses the `webextension-polyfill`!

 To upgrade, you have two options:
 
-1. **Stop using the polyfill** - No changes necessary, though you may want to do some manual testing to make sure everything continues to work. None of the early testers of this feature reported any runtime issues once they stopped using the polyfill.
-   - If you're already using `extensionApi: "chrome"`, then you don't need to test anything! You're already using the same `browser` object v0.20 provides by default.
+1. **Stop using the polyfill**
+   - If you're already using `extensionApi: "chrome"`, then you're not using the polyfill and there is nothing to change!
+   - Otherwise there is only one change: `browser.runtime.onMessage` no longer supports using promises to return a response:
+
+     ```ts
+     browser.runtime.onMessage.addListener(async () => { // [!code --]
+       const res = await someAsyncWork(); // [!code --]
+       return res; // [!code --]
+     browser.runtime.onMessage.addListener(async (_message, _sender, sendResponse) => { // [!code ++]
+       someAsyncWork().then((res) => { // [!code ++]
+         sendResponse(res); // [!code ++]
+       }); // [!code ++]
+       return true; // [!code ++]
+     });
+     ```
+
 2. **Continue using the polyfill** - If you want to keep using the polyfill, you can! One less thing to worry about during this upgrade.
    - Install `webextension-polyfill` and WXT's [new polyfill module](https://www.npmjs.com/package/@wxt-dev/webextension-polyfill):

      ```sh

+# `@wxt-dev/runner`
+
+Programmatically open a browser and install a web extension from a local directory.
+
+## Usage
+
+### With WXT
+
+> [!WARNING]
+> This package is intended to replace [`web-ext`](https://github.com/mozilla/web-ext) in the future, but it is not ready at the moment. Once it's ready for testing in WXT, more details will be added here.
+
+```ts
+// ~/wxt.runner.config.ts OR <project>/wxt.runner.config.ts
+import { defineRunnerConfig } from 'wxt';
+
+export default defineRunnerConfig({
+  // Options go here
+});
+```
+
+### JS API
+
+```ts
+import { run } from '@wxt-dev/runner';
+
+await run({
+  extensionDir: '/path/to/extension',
+  // Other options...
+});
+```
+
+## Features
+
+- Supports all Chromium and Firefox based browsers
+- Zero dependencies
+- One-line config for persisting data between launches
+
+## Requirements
+
+`@wxt-dev/runner` requires a JS runtime that implements the `WebSocket` standard:
+
+| JS Runtime | Version     |
+| ---------- | ----------- |
+| NodeJS     | &ge; 22.4.0 |
+| Bun        | &ge; 1.2.0  |
+
+You also need to have a specific version of the browser installed that supports the latest features so extensions can be loaded:
+
+| Browser  | Version  |
+| -------- | -------- |
+| Chromium | Unknown  |
+| Firefox  | &ge; 139 |
+
+## TODO
+
+- [x] Provide install functions to allow hooking into already running instances of Chrome/Firefox
+  - [ ] Try to setup E2E tests on Firefox with Puppeteer using this approach
+  - [ ] Try to setup E2E tests on Chrome with Puppeteer using this approach
+
+## Options
+
+### Target
+
+To open a specific browser, use the `target` option:
+
+```ts
+import { run } from '@wxt-dev/runner';
+
+await run({
+  extensionDir: 'path/to/extension',
+  target: 'firefox',
+});
+```
+
+Defaults to opening `chrome`. You may see type-hints for a list of popular browsers, but you can enter any string you want here.
+
+### Data Persistence
+
+Browsers block you from using your normal browser profiles when using the [BiDi and CDP protocols](#implementation-details) for security reasons.
+
+To change how the new profile's data is saved between sessions, use the `dataPersistence` option:
+
+```ts
+import { run } from '@wxt-dev/runner';
+
+await run({
+  dataPersistence: 'user',
+});
+```
+
+- `"none"` (default): Use a brand new browser profile every time the browser is opened (stored in the system's tmp directory)
+- `"project"`: Create a new profile that is re-used for your current directory (by default stored in `.wxt-runner` or `.wxt/runner` for WXT projects)
+- `"user"`: Create a new profile that is re-used for all projects using `@wxt-dev/runner` (by default stored in `$HOME/.wxt-runner`)
+
+These presets configure different flags for different operating systems when spawning the browser process.
+
+If you want to customize your data persistence beyond what these presets define, [you can override the browser flags yourself](#arguments) to configure persistence.
+
+### Browser Binaries
+
+`@wxt-dev/runner` will look for browser binaries/executables in [a hard-coded list of paths](https://github.com/wxt-dev/wxt/blob/main/packages/runner/src/browser-paths.ts). It does not and will not explore your filesystem/`$PATH` to find where the browser is installed. That means there are times you will need to specify the path to a browser's binary on your system:
+
+- Your browser's path is non-standard or missing from the hard-coded list.
+- You want to use a specific version/release of the browser.
+- You're using a less popular browser and `@wxt-dev/runner` doesn't have hard-coded paths for it.
+
+To do this, use the `browserBinaries` option and set the path to the browser's binary:
+
+```ts
+import { run } from '@wxt-dev/runner';
+
+await run({
+  extensionDir: 'path/to/extension',
+  browserBinaries: {
+    chrome: '/path/to/chrome',
+    firefox: '/path/to/firefox',
+  },
+});
+```
+
+### Arguments
+
+To pass custom arguments to the browser on startup, use the `chromiumArgs` or `firefoxArgs` options:
+
+```ts
+import { run } from '@wxt-dev/runner';
+
+await run({
+  extensionDir: 'path/to/extension',
+  chromiumArgs: ['--window-size=1920,1080'],
+  firefoxArgs: ['--window-size', '1920,1080'],
+});
+```
+
+### Start URLs
+
+To open specific URLs in tabs by default, you also use the `chromiumArgs` or `firefoxArgs` options.
+
+Any URLs passed as a CLI argument will be opened in the browser when it starts.
+
+```ts
+import { run } from '@wxt-dev/runner';
+
+await run({
+  extensionDir: 'path/to/extension',
+  chromiumArgs: ['https://example.com'],
+  firefoxArgs: ['https://example.com'],
+});
+```
+
+### Debugging
+
+To see debug logs, set the `DEBUG` env var to `"@wxt-dev/runner"`. This will print the resolved config, commands used to spawn the browser, any messages sent on the browser's communication protocol, and more for you to debug.

+
+## Implementation Details
+
+All this package does is spawn a child process to open the browser with some default flags before using remote protocols to install the extension.
+
+### Firefox
+
+We use the new [WebDriver BiDi protocol](https://www.w3.org/TR/webdriver-bidi) to install the extension. This just involves connecting to a web socket and sending a few messages.
+
+### Chrome
+
+We use the [CDP](https://chromedevtools.github.io/devtools-protocol/) with `--remote-debugging-pipe` and `--enable-unsafe-extension-debugging` to install the extension by sending a message via IO pipes 3 and 4.
+
+We don't use Webdriver Bidi because it's not built into Chrome yet. It requires us instantiating a separate child process for `chromedriver`. This is slower and more difficult than just using the CDP built into Chrome.
