+`SchemaRender` is a set of `simple by default`, but also pursues `flexible`, `highly customizable` and `easy to use` form rendering solutions. It aims to precipitate a rendering library to solve common form cases, and related common components , to improve development efficiency.
+
+Table of Contents:
+
+- `Core`: The core of the form rendering library, which builds a set of forms through a simple JSON Schema. The core mainly handles the Schema protocol, renderer arrangement, logical linkage, verification capabilities, etc., and supports SSR (Server-Side Rendering).
+  - Features: Protocol driven, easy to use, highly customizable, lightweight and zero dependency.
+- `FormRender`: An out-of-the-box form rendering library based on Core + [Antd](https://ant.design).
+- `Search`: out-of-the-box conditional search component based on FormRender.
+- `SearchTable`: A conditional search table based on Search + Antd Table (under construction).
