 ## Can I create a pull request for Uptime Kuma?
 
-⚠️ 2022-03-02 Update:
+Yes, you can. However, since I don't want to waste your time, be sure to **create empty draft pull request, so we can discuss first** if it is a large pull request or you don't know it will be merged or not.
 
-Since I found that merging pull requests is a pretty heavy task for me, I try to rearrange it.
+Also, please don't rush or ask for ETA, because I have to understand the pull request, make sure it is no breaking changes and stick to my vision of this project, especially for large pull requests.
+
+I will mark your pull request in the [milestones](https://github.com/louislam/uptime-kuma/milestones), if I am plan to review and merge it.

 ## Project Styles
 
 I personally do not like something need to learn so much and need to config so much before you can finally start the app.
 
 - Easy to install for non-Docker users, no native build dependency is needed (at least for x86_64), no extra config, no extra effort to get it run
 - Single container for Docker users, no very complex docker-compose file. Just map the volume and expose the port, then good to go
-- Settings should be configurable in the frontend. Env var is not encouraged.
+- Settings should be configurable in the frontend. Environment variable is not encouraged, unless it is related to startup such as `DATA_DIR`.
 - Easy to use
+- The web UI styling should be consistent and nice.
 
 ## Coding Styles
 
 - 4 spaces indentation
 - Follow `.editorconfig`
 - Follow ESLint
+- Methods and functions should be documented with JSDoc
 
 ## Name convention
 
 - Javascript/Typescript: camelCaseType
-- SQLite: underscore_type
-- CSS/SCSS: dash-type

-## How to start the Backend Dev Server
+## Dev Server
 
-(2021-09-23 Update)
+(2022-04-26 Update)
+
+We can start the frontend dev server and the backend dev server in one command.
+
+Port `3000` and port `3001` will be used.
 
 ```bash
-npm run start-server-dev
+npm run dev
 ```
 
+## Backend Server
+
 It binds to `0.0.0.0:3001` by default.
 
-### Backend Details
 
 It is mainly a socket.io app + express.js.
 
-express.js is just used for serving the frontend built files (index.html, .js and .css etc.)
+express.js is used for: 
+- entry point such as redirecting to a status page or the dashboard
+- serving the frontend built files (index.html, .js and .css etc.)
+- serving internal APIs of status page
+
+
+### Structure in /server/
 
 - model/ (Object model, auto mapping to the database table name)
 - modules/ (Modified 3rd-party modules)
 - notification-providers/ (individual notification logic)
 - routers/ (Express Routers)
 - socket-handler (Socket.io Handlers)
-- server.js (Server main logic)
+- server.js (Server entry point and main logic)
 
-## How to start the Frontend Dev Server
+## Frontend Dev Server
 
-1. Set the env var `NODE_ENV` to "development".
-2. Start the frontend dev server by the following command.
+It binds to `0.0.0.0:3000` by default. Frontend dev server is used for development only. 
 
-   ```bash
-   npm run dev
-   ```
-
-   It binds to `0.0.0.0:3000` by default.
+For production, it is not used. It will be compiled to `dist` directory instead. 
 
 You can use Vue.js devtools Chrome extension for debugging.
