+# TestData CLI
+
+A CLI tool that generates realistic test data from JSON Schema, TypeScript types, or sample data files using Faker-style generation.
+
+## Features
+
+- Generate realistic test data from JSON Schema
+- Support for Faker-style data generation (names, emails, addresses, dates)
+- Bulk data generation with configurable count
+- Multiple output formats: JSON, CSV, and SQL
+- Generate from TypeScript types
+- Generate from sample data files
+- Custom pattern support with regex-based generation
+- Seed support for reproducible data generation
+
+## Installation
+
+```bash
+pip install testdata-cli
+# or
+pip install -e .
+```
+
+## Quick Start
+
+Generate data from a JSON Schema file:
+
+```bash
+testdatagen generate --schema schema.json --count 10
+```
+
+Generate with specific output format:
+
+```bash
+testdatagen generate --schema schema.json --format csv --count 5
+```
+
+Use a seed for reproducible results:
+
+```bash
+testdatagen generate --schema schema.json --seed 12345
+```
+
+## Commands
+
+### generate
+
+Generate test data from a JSON Schema file.
+
+```bash
+testdatagen generate --schema <file> [options]
+```
+
+Options:
+- `--schema`, `-s`: Path to JSON Schema file (required)
+- `--count`, `-n`: Number of records to generate (default: 10)
+- `--format`, `-f`: Output format - json, csv, or sql (default: json)
+- `--seed`: Random seed for reproducibility
+- `--table`: Table name for SQL output (default: generated_table)
+
+### from-ts
+
+Generate test data from a TypeScript type definition.
+
+```bash
+testdatagen from-ts --input <file.ts> [options]
+```
+
+### from-sample
+
+Generate test data from a sample data file.
+
+```bash
+testdatagen from-sample --input <file.json> [options]
+```
+
+## Configuration
+
+Default options can be configured in `~/.testdatagen.yaml`:
+
+```yaml
+default-seed: 42
+default-count: 10
+```
+
+Or in `pyproject.toml`:
+
+```toml
+[tool.testdatagen]
+default-seed = 42
+default-count = 10
+```
