+# jsonforms-parser
+
+A dependency-free Go parser for [JSON Forms](https://jsonforms.io) schemas. Produces a type-safe AST for building custom renderers.
+
+## Features
+
+- **All Standard Elements** - Control, Layout, Group, Categorization, Category, Label
+- **Custom Elements** - Unknown types preserved with parsed children
+- **Rules & Conditions** - HIDE/SHOW/ENABLE/DISABLE with schema-based, leaf, AND, OR conditions
+- **Visitor Pattern** - Traverse and transform the AST
+- **Type-Safe** - Strongly-typed nodes, no generic maps
+- **Zero Dependencies** - Pure Go stdlib
+
+## Installation
+
+```bash
+go get github.com/tinybluerobots/jsonforms-parser
+```
+
+## Usage
+
+```go
+import "github.com/tinybluerobots/jsonforms-parser"
+
+ast, err := jsonforms.Parse(uiSchemaJSON, schemaJSON)
+if err != nil {
+    log.Fatal(err)
+}
+
+layout := ast.UISchema.(*jsonforms.VerticalLayout)
+control := layout.Elements[0].(*jsonforms.Control)
+fmt.Println(control.Scope) // "#/properties/name"
+```
+
+## Elements
+
+All elements implement `UISchemaElement`:
+- `Control` - Binds UI to data property
+- `VerticalLayout`, `HorizontalLayout` - Layout containers
+- `Group` - Labeled container
+- `Categorization`, `Category` - Tab navigation
+- `Label` - Static text
+- `CustomElement` - Unknown/custom types
+
+## Visitor Pattern
+
+```go
+type MyVisitor struct {
+    jsonforms.BaseVisitor
+}
+
+func (v *MyVisitor) VisitControl(c *jsonforms.Control) error {
+    fmt.Println("Found:", c.Scope)
+    return nil
+}
+
+jsonforms.Walk(ast.UISchema, &MyVisitor{})
+```
+
+## Use Cases
+
+Build custom renderers, transform schemas, validate structures, generate docs, or convert between form systems.
