+# Big Chef
+
+A Go-based tool for modifying XML, JSON, and text documents using XPath/JSONPath/Regex expressions and Lua transformations.
+
+## Features
+
+- **Multi-Format Processing**:
+  - XML (XPath)
+  - JSON (JSONPath) 
+  - Text (Regex)
+- **Node Value Modification**: Update text values in XML elements, JSON properties or text matches
+- **Attribute Manipulation**: Modify XML attributes, JSON object keys or regex capture groups
+- **Conditional Logic**: Apply transformations based on document content
+- **Complex Operations**: 
+  - Mathematical calculations
+  - String manipulations
+  - Date conversions
+  - Structural changes
+  - Whole ass Lua environment
+- **Error Handling**: Comprehensive error detection for:
+  - Invalid XML/JSON
+  - Malformed XPath/JSONPath
+  - Lua syntax errors
+
+## Usage Examples
+
+### 1. Basic field modification
+```xml
+<!-- Input -->
+<price>44.95</price>
+
+<!-- Command -->
+chef -xml "//price" "v=v*2" input.xml
+
+<!-- Output -->
+<price>89.9</price>
+```
+
+### 2. Supports glob patterns
+```xml
+chef -xml "//price" "v=v*2" data/**.xml
+```
+
+### 3. Attribute Update
+```xml
+<!-- Input -->
+<item price="10.50"/>
+
+<!-- Command -->
+chef -xml "//item/@price" "v=v*2" input.xml
+
+<!-- Output --> 
+<item price="21"/>
+```
+
+### 3. JSONPath Transformation
+```json
+// Input
+{
+  "products": [
+    {"name": "Widget", "price": 19.99},
+    {"name": "Gadget", "price": 29.99}
+  ]
+}
+
+// Command
+chef -json "$.products[*].price" "v=v*0.75" input.json
+
+// Output
+{
+  "products": [
+    {"name": "Widget", "price": 14.99},
+    {"name": "Gadget", "price": 22.49}
+  ]
+}
+```
+
+### 4. Regex Text Replacement
+Regex works slightly differently, up to 12 match groups are provided as v1..v12 and s1..s12 for numbers and strings respectively.
+A special shorthand "!num" is also provided that simply expands to `(\d*\.?\d+)`.
+```xml
+<!-- Input -->
+<description>Price: $15.00 Special Offer</description>
+
+<!-- Command -->
+chef "Price: $!num Special Offer" "v1 = v1 * 0.92" input.xml
+
+<!-- Output -->
+<description>Price: $13.80 Special Offer</description>
+```
+
+### 5. Conditional Transformation
+```xml
+<!-- Input -->
+<item stock="5" price="10.00"/>
+
+<!-- Command -->
+chef -xml "//item" "if tonumber(v.stock) > 0 then v.price = v.price * 0.8 end" input.xml
+
+<!-- Output -->
+<item stock="5" price="8.00"/>
+```
+
+## Installation
+
+```bash
+go build -o chef main.go
+```
+
+```bash
+# Process XML file
+./chef -xml "//price" "v=v*1.2" input.xml
+
+# Process JSON file 
+./chef -json "$.prices[*]" "v=v*0.9" input.json
+```
