+## Dev Mode
+
+WXT's main goal is improving the development experience (DX) of creating web extensions. There are two things WXT does differently:
+
+1. Automatically opens a browser with the extension installed when starting development
+2. Reload each part of the extension individually rather than reloading the entire extension
+
+Opening a browser automatically makes it super easy to start and stop development without having to manually load the extension in your browser.
+
+Reloading each part of the extension individually improves your iteration speed while developing UIs. This is because reloading the entire extension on every change will close the popup and any tabs open to an extension page, like options. If you save a file associated with a UI and a content script while working on the UI, it will randomly close because it needed to reload the extension when the content script changed. This interupts your development flow and is really annoying.
+
+WXT solves this problem by reloading HTML pages and content scripts individually (when possible) to keep your UIs open while you develop them. This is a MV3 feature, so if you're developing a MV2 extension, you'll get the same dev experience as Plasmo.
+
+:::info
+Unfortunately, there isn't an API for reloading the background page/service worker individually, so if you change a file used by the background, the entire extension will reload. See [Issue #53](https://github.com/aklinker1/wxt/issues/53) for more details.

 # Publishing
 
-:::warning 🚧 Not implemented yet!
-For now, manually zip the output directory and upload to stores by hand.
+WXT offers several utilities that simplify the publishing process.
+
+## First Time Publishing
+
+If you're publishing an extension to a store for the first time, it's recommended that you manually navigate the process. Each store has unique steps and requirements that you need to familiarize yourself with.
+
+Each store requires that a ZIP file be uploaded. You can generate these using the `wxt zip` command:
+
+```sh
+wxt zip
+wxt zip -b firefox
+# etc
+```
+
+Generated ZIP files are stored in the `.output` directory.
+
+## Setup Automated Submissions
+
+To automate submissions, use the [`publish-browser-extension`](https://www.npmjs.com/package/publish-browser-extension) package.
+
+:::info
+🚧 WXT plans to eventually incorporate the `publish-browser-extension` package into its own `wxt submit` command.
 :::
+
+1. Install the necessary dependencies:
+
+   ```sh
+   pnpm add -D publish-browser-extension env-cmd
+   ```
+
+2. Add scripts to your `package.json` file:
+
+   ```json
+   {
+     "scripts": {
+       "submit": "env-cmd -f .env.submit -- publish-extension",
+       "submit:dry": "env-cmd -f .env.submit -- publish-extension --dry-run"
+     }
+   }
+   ```
+
+3. Create a `.env.submit` file and include the code below. If you're not publishing to certain stores, simply ignore their respective variables.
+
+   ```txt
+   CHROME_EXTENSION_ID=""
+   CHROME_CLIENT_ID=""
+   CHROME_CLIENT_SECRET=""
+   CHROME_REFRESH_TOKEN=""
+
+   FIREFOX_EXTENSION_ID=""
+   FIREFOX_JWT_ISSUER=""
+   FIREFOX_JWT_SECRET=""
+
+   EDGE_PRODUCT_ID=""
+   EDGE_CLIENT_ID=""
+   EDGE_CLIENT_SECRET=""
+   EDGE_ACCESS_TOKEN_URL=""
+   ```
+
+   > Each value will be filled in during the next step.
+
+4. Run `npx publish-extension --help` for assistance with filling out all the values. Insert the obtained values within the double quotes.
+
+5. ZIP all the targets you plan to publish, in this case Chrome and Firefox.
+
+   ```sh
+   wxt zip
+   wxt zip -b firefox
+   ```
+
+6. Test your credentials by running the `submit:dry` command:
+
+   ```sh
+   pnpm submit:dry \
+     --chrome-zip .output/your-extension-X.Y.Z-chrome.zip \
+     --firefox-zip .output/your-extension-X.Y.Z-firefox.zip \
+     --firefox-sources-zip .output/your-extension-X.Y.Z-sources.zip \
+     --edge-zip .output/your-extension-X.Y.Z-chrome.zip
+   ```
+
+7. Upload and submit your extension for review:
+
+   ```sh
+   pnpm submit \
+     --chrome-zip .output/your-extension-X.Y.Z-chrome.zip \
+     --firefox-zip .output/your-extension-X.Y.Z-firefox.zip \
+     --firefox-sources-zip .output/your-extension-X.Y.Z-sources.zip \
+     --edge-zip .output/your-extension-X.Y.Z-chrome.zip
+   ```

+Firefox requires you to upload a ZIP of your source code. This allows them to rebuild your extension and review the code in a readable way. More details can be found in [Firefox's docs](https://extensionworkshop.com/documentation/publish/source-code-submission/).
+
+WXT and `publish-browser-extension` both fully support generating and automatically submitting a source code ZIP.
+
+When you run `wxt zip -b firefox`, your sources are zipped into the `.output` directory along with your built extension. WXT is configured to exclude certain files such as config files, hidden files, and tests. However, it's important to manually check the ZIP to ensure it only contains the files necessary to rebuild your extension.
+
+To customize which files are zipped, add the `zip` option to your config file.
+
+```ts
+// wxt.config.ts
+import { defineConfig } from 'wxt';
+
+export default defineConfig({
+  zip: {
+    // ...
+  },
+});
+```
+
+If it's your first time submitting to the Firefox Addon Store, or if you've updated your project layout, always test your sources ZIP! The commands below should allow you to rebuild your extension from inside the extracted ZIP.
+
+:::code-group
+
+```sh [pnpm]
+pnpm i
+pnpm zip:firefox
+```
+
+```sh [npm]
+npm i
+npm run zip:firefox
+```
+
+```sh [yarn]
+yarn
+yarn zip:firefox
+```
+
+:::
+
+Ensure that you have a `README.md` or `SOURCE_CODE_REVIEW.md` file with the above commands so that the Firefox team knows how to build your extension.
+
+## Safari
+
+🚧 Not automated at this time
+
+:::warning
+🚧 WXT does not currently support automated publishing for Safari. Safari extensions require a native MacOS or iOS app wrapper, which WXT isn't configured to create. For now, if you want to publish to Safari, follow this guide:
