+# Rust Validator
+
+A Rust CLI tool for validating `.gitinfo` files.
+
+## Requirements
+
+- Rust 1.70+ (with Cargo)
+
+## Build
+
+```bash
+cd validators/rust
+cargo build --release
+```
+
+The binary will be at `target/release/validate` (or `validate.exe` on Windows).
+
+## Usage
+
+```bash
+# Validate .gitinfo in current directory
+./target/release/validate
+
+# Validate a specific file
+./target/release/validate path/to/.gitinfo
+```
+
+Or run directly with Cargo:
+
+```bash
+cargo run -- path/to/.gitinfo
+```
+
+## Features
+
+- Parses JSONC (strips `//` and `/* */` comments)
+- Removes trailing commas (valid in JSONC, invalid in JSON)
+- Validates against the gitinfo JSON Schema
+- Checks types, formats (URI, email), and patterns
+- Enforces `additionalProperties: false`
+- Returns exit code 0 on success, 1 on failure
+- Color-coded output (green for success, red for errors)
+
+## Example Output
+
+```
+✓ .gitinfo is valid
+```
+
+```
+Validation failed for .gitinfo:
+  - .root: invalid URI "not-a-url"
+  - root: unknown property "invalid_field"
+```
+
+## Dependencies
+
+- `serde` / `serde_json` - JSON parsing
+- `json_comments` - JSONC comment stripping
+- `regex` - Pattern matching for validation
