+
+A low-code front-end framework that allows you to generate various backend pages using JSON configuration, greatly reducing development costs, and even eliminating the need for front-end expertise.
+
+## Development Guide
+
+The following is for those who want to contribute to the development of amis. For usage, refer to the documentation above.
+
+> If GitHub downloads are slow, you can use the mirror on [gitee](https://gitee.com/baidu/amis).
+
+Node.js versions 12/14/16 are recommended. Use npm 7+ because the workspaces feature is required.
+
+```bash
+# Install project dependencies. There may be errors with Node.js 12, but they don't affect normal use.
+npm i --legacy-peer-deps
+
+# Start the project. Once compilation is complete, access it at http://127.0.0.1:8888/examples/pages/simple.
+npm start
+```
+
+If you're developing the editor, access it at `http://127.0.0.1:8888/packages/amis-editor/`.
+
+### Testing
+
+> Note: After modifying code locally, you must run npm run build to complete compilation before executing test cases (`npm test --workspaces`), as Jest doesn't support TypeScript directly.
+
+```bash
+# Install dependencies
+npm i --legacy-peer-deps
+
+# Build the project
+npm run build
+
+# Run all test cases
+npm test --workspaces
+
+# Run a specific test case
+# <spec-name> is the name of the test case, e.g., inputImage
+npm test --workspace amis -- -t <spec-name>
+
+# Run a specific test file
+./node_modules/.bin/jest packages/amis/__tests__/renderers/Form/buttonToolBar.test.tsx
+
+# Run a specific example in a test file
+./node_modules/.bin/jest packages/amis/__tests__/renderers/Form/buttonToolBar.test.tsx -t 'Renderer:button-toolbar'
+
+# View test coverage
+npm run coverage
+
+# Update snapshots
+npm run update-snapshot
+
+# Update a single snapshot
+# <spec-name> is the name of the test case, e.g., inputImage
+npm run update-snapshot --workspace amis -- -t <spec-name>
+```
+
+### Release Version
+
+```bash
+# Publish to internal registry
+npm run publish
+
+# Publish to external environment
+# First, set the version number with the following command
+npm run version
+npm run release
+```
+
+### How to Contribute
+
+Please use a branch for development. First, create a branch:
+
+    git checkout -b feat-xxx
+
+After committing your changes, use `git push --set-upstream origin feat-xxx` to create a remote branch.
+
+Then submit a PR using the system-generated link: https://github.com/xxx/amis/pull/new/feat-xxx.
+
+Please write in TypeScript. All reasonable changes, new public renderers, test cases, or documentation submissions will be accepted.
