 # Pipe
 
-**Warning: This function under development and is not yet publicly available.**
+Pipe Widget is used for complex logic orchestration, serving as an alternative to Flow.
 
-A new workflow orchestration engine designed to solve complex workflow orchestration problems. This is an alternative to **Flow**.
+**Warning**:
+
+Pipe Widget is an experimental feature and not recommended for production use.
+
+**Usage Scenario**
+
+Generating DSL from a graphical interface, implementing simple functional logic extensions on the application side.
+
+## DSL
+
+CLI: https://github.com/YaoApp/yao-dev-app/blob/main/pipes/cli/translator.pip.yao
+
+WEB: https://github.com/YaoApp/yao-dev-app/blob/main/pipes/web/translator.pip.yao
+
+## Node Types
+
+| Type        | options                      | Description                                               |
+| ----------- | ---------------------------- | --------------------------------------------------------- |
+| Yao Process | `name`, `args`               | run yao process                                           |
+| Switch      |                              | conditional branch                                        |
+| AI          | `prompts`, `model`, `option` | AI interface                                              |
+| Request     |                              | HTTP request (not supported yet, use yao process instead) |
+| User Input  | `ui` (cli/web/...)           | user input interface                                      |
+
+for more details, refer to the DSL demo.
+
+## Process
+
+Refer to unit test programs for examples.
+
+### pipes.<Widget.ID>
+
+Run Pipe
+
+```bash
+yao run pipes.<Widget.ID> [args...]
+```
+
+If interrupted by user input interface, it returns a context ID for resuming execution.
+
+### pipe.Run
+
+Run Pipe, equivalent to `pipes.<Widget.ID>`
+
+```bash
+yao run pipe.run <Widget.ID> [args...]
+```
+
+### pipe.Create
+
+Pass DSL text to create and run Pipe
+
+```bash
+yao run pipe.create <DSL> [args...]
+```
+
+### pipe.Resume
+
+Resume execution, used for context restoration
+
+```bash
+yao run pipe.Resume <Context.ID> [args...]
+```
+
+### pipe.Close
+
+Close Pipe
+
+```bash
+yao run pipe.Close <Context.ID>
+```
+
+## Features
+
+- [x] **Yao Process Node** Support for running yao process
+- [x] **Switch Node** Conditional branch
+- [x] **AI Node** AI interface
+- [x] **User Input Node** User input interface
+- [ ] **Request Node** Support for Http Request
+- [ ] **Hooks** Progress report for hook integration
