 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.

+# Maintainers
+
+A couple of things for you to consider before merging a PR or giving the go-ahead on a feature proposal.
+
+## 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.

+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', {
+      modifyScript(script) {
+        script.dataset['greeting'] = 'Hello there';
+      },
+    });
+  },
+});
+```
+
+```ts
+// entrypoints/example-main-world.ts
+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({
+  matches: ['*://*/*'],
+  async main() {
+    const { script } = await injectScript('/example-main-world.js', {
+      modifyScript(script) {
+        // Add a listener before the injected script is loaded.
+        script.addEventListener('from-injected-script', (event) => {
+          if (event instanceof CustomEvent) {
+            console.log(`${event.type}:`, event.detail);
+          }
+        });
+      },
+    });
+
+    // Send an event after the injected script is loaded.
+    script.dispatchEvent(
+      new CustomEvent('from-content-script', {
+        detail: 'General Kenobi',
+      }),
+    );
+  },
+});
+```
+
+```ts
+// entrypoints/example-main-world.ts
+export default defineUnlistedScript(() => {
+  const script = document.currentScript;
+
+  script?.addEventListener('from-content-script', (event) => {
+    if (event instanceof CustomEvent) {
+      console.log(`${event.type}:`, event.detail);
+    }
+  });
+
+  script?.dispatchEvent(
+    new CustomEvent('from-injected-script', {
+      detail: 'Hello there',
+    }),
+  );
+});

 ## 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.
+```
+
+The fix is simple, just move your API usage into the entrypoint's main function:
+
+:::code-group
+
+```ts [background.ts]
+browser.action.onClicked.addListener(() => {
+  /* ... */
+}); // [!code --]
