+This project only has one main branch, namely the `main` branch. If you want to participate in the
+development of Gopeed, please fork this project first, and then develop in your fork project. After
+development is completed, submit a PR to this project and merge it into the `main` branch.
+
+## Local development
+
+It is recommended to develop and debug through the web. First, start the backend service, and start
+it by the command line `go run cmd/api/main.go`, the default port of the service is `9999`, and then
+start the front-end flutter project in `debug` mode to run.
+
+## Translation
+
+The internationalization files of Gopeed are located in the `ui/flutter/assets/locales` directory.
+You only need to add the corresponding language file in this directory.
+
+
+Generate locales after you edit locales:
+
+
+```
+get generate locales 
+```
+
+Please refer to `en_us.dart` for translation.
+
+## flutter development
+
+Don't forget to run`dart format ./ui/flutter`before you commit to keep your code in standard dart format
+
+Turn on build_runner watcher if you want to edit api/models:
+
+```
+flutter pub run build_runner watch
+```
+
+
+get-cli commands usages:
+
+```
+ create:  
+    controller:  Generate controller
+    page:  Use to generate pages
+    view:  Generate view
+  generate:
+    locales:  Generate translation file from json files
+    model:  generate Class model from json
+```

+# Gopeed 贡献指南
+
+首先感谢您对贡献代码感兴趣，这份指南将帮助您更好的参与到 Gopeed 的开发中来。
+
+## 分支说明
+
+本项目只有一个主分支，即 `main` 分支，如果您想要参与到 Gopeed 的开发中来，请先 fork 本项目，然后在您的 fork 项目中进行开发，开发完成后再向本项目提交
+PR，合并到 `main` 分支。
+
+## 本地开发
+
+建议通过 web 端进行开发调试，首先启动后端服务，通过命令行 `go run cmd/api/main.go` 启动 ，服务启动默认端口为 `9999`，然后以 `debug` 模式启动前端
+flutter 项目即可运行。
+
+## 翻译
+ 
+Gopeed 的国际化文件位于 `ui/flutter/assets/locales` 目录下，只需要在该目录下添加对应的语言文件即可。
+
+编辑locales后请运行以下命令:
+
+```
+get generate locales 
+```
+
+请注意以 `en_US.json` 为参照进行翻译。
+
+## flutter开发
+
+每次提交前请务必`dart format ./ui/flutter`
+
+如果要编辑api/models，请打开build_runner watcher:
+
+```
+flutter pub run build_runner watch
+```
+
+适用get-cli 命令:
+
+```
+ create:  
+    controller:  Generate controller
+    page:  Use to generate pages
+    view:  Generate view
+  generate:
+    locales:  Generate translation file from json files
+    model:  generate Class model from json
+```
