-# Ani-Relayer
+This is a [Plasmo extension](https://docs.plasmo.com/) project bootstrapped with [`plasmo init`](https://www.npmjs.com/package/plasmo).
 
-> **⚠️ This app is under heavy development.**
+## Getting Started
 
-<img width="1280" height="800" alt="hero" src="https://github.com/user-attachments/assets/f1b5de22-3036-4220-841a-a4512dcecc9b" />
+First, run the development server:
 
-## Getting Started
-[Download At Chrome Web Store](https://chromewebstore.google.com/detail/ghmmhbenboneanchpohomkbpiechghkn?utm_source=item-share-cb)
+```bash
+pnpm dev
+# or
+npm run dev
+```
 
-## Summary
-laftel에서 제공하고 있는 애니메이션들을, DRM 우회 없이 서로 같이 감상하기 위해 제작했습니다. \
-애니메이션 재생시간을 서버에서 관리하고 일괄적으로 propagate해서 같은 시간대에 같은 시점을 볼 수 있게 합니다.
+Open your browser and load the appropriate development build. For example, if you are developing for the chrome browser, using manifest v3, use: `build/chrome-mv3-dev`.
 
-각 참여자들은 모두 laftel서비스에서 제공하는 계정이 존재해야 하며,
+You can start editing the popup by modifying `popup.tsx`. It should auto-update as you make changes. To add an options page, simply add a `options.tsx` file to the root of the project, with a react component default exported. Likewise to add a content page, add a `content.ts` file to the root of the project, importing some module and do some logic, then reload the extension on your browser.
 
-**⚠️ laftel과는 관련이 없는 서드파티 프로그램입니다.**
+For further guidance, [visit our Documentation](https://docs.plasmo.com/)
 
-## Stack
+## Making production build
 
-- [Plasmo](https://www.plasmo.com/) for the Extension itself.
-- [SocketIO](https://socket.io/) for realtime BE communication.
-- [Nestjs](https://nestjs.com/) for Backend Server.
+Run the following:
 
-## Builds(for Beta-Testing)
 ```bash
-pnpm install
 pnpm build
+# or
+npm run build
 ```
-build 결과물로 나온 directory를 chrome extensions에 수동으로 추가합니다.
 
-## Sequence Diagram - MV3 flow
+This should create a production bundle for your extension, ready to be zipped and published to the stores.
+
+## Submit to the webstores

+The easiest way to deploy your Plasmo extension is to use the built-in [bpp](https://bpp.browser.market) GitHub action. Prior to using this action however, make sure to build your extension and upload the first version to the store to establish the basic credentials. Then, simply follow [this setup instruction](https://docs.plasmo.com/framework/workflows/submit) and you should be on your way for automated submission!
