-Please make sure you use `node 16+` and `pnpm` to manage the dependencies of the project.
+> After two and a half months of development cycle, we have brought a brand-new `UI` management system (V1.0.0-Alpha).
+> 
+> Compared with the old `UI`, it will be more standardized, and it will also have a more complete type checking mechanism. At the same time, its speed has made a qualitative leap.
+> 
+> We also provide dark mode and light mode to meet the preferences of different developers. It will make your eyes shine.
+> 
+> If you have tried the new `UI` and found problems in use, you can contact us through issue.

+#### Install Dependencies
+
+```shell
+pnpm install
+```
+
+
+#### Start Development Project
+
+To do this you need to change the `VITE_APP_DEV_WEB_URL` parameter variable in `.env.development` in the project root directory.
+
+It is worth noting that when you do not change the request path or route, you only need to write `http`, `ip` and `port` without the `/` symbol at the end, such as `http://127.0. 0.1:12345`.
+
+```shell
+pnpm run dev
+```
+
+#### Build Project
+
+We provide two packaging and compilation environments by default, `development` and `production`. Their interface request configurations are in `.env.development` and `.env.production` in the project root directory respectively. Please change the `URL` is the address of the corresponding backend service.
+
+```shell
+pnpm run build:dev
+# or
+pnpm run build:prod
+```
