-# hdlbuild
+# HDLBuild
 
+HDLBuild is a flexible build management tool for FPGA projects. It simplifies the process of managing dependencies, building, testing, and deploying FPGA designs using Xilinx ISE tools.
+
+## Features
+
+- **Dependency Management**: Automatically resolves and manages project dependencies from Git repositories.
+- **Build Automation**: Supports synthesis, implementation, and bitstream generation for FPGA designs.
+- **Testbench Execution**: Automates the process of building and running testbenches.
+- **Customizable Tool Options**: Provides extensive configuration options for Xilinx ISE tools.
+- **Project Initialization**: Quickly set up new projects with predefined templates.
+- **Rich Console Output**: Provides detailed and interactive console feedback using `rich`.
+
+---
+
+## Installation
+
+### Prerequisites
+
+- Python 3.10 or higher
+- Poetry (for dependency management)
+- Xilinx ISE (14.7) installed and configured
+
+### Steps
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/your-repo/hdlbuild.git
+   cd hdlbuild
+   ```
+
+2. Install dependencies:
+   ```bash
+   poetry install
+   ```
+
+3. Add the `hdlbuild` CLI to your PATH:
+   ```bash
+   poetry shell
+   ```
+
+---
+
+## Usage
+
+### CLI Commands
+
+HDLBuild provides a command-line interface (CLI) for managing FPGA projects. Below are the available commands:
+
+#### 1. **Initialize a New Project**
+   ```bash
+   hdlbuild init
+   ```
+   - Creates a new project with a project.yml configuration file and a .gitignore file.
+
+#### 2. **Resolve Dependencies**
+   ```bash
+   hdlbuild dep
+   ```
+   - Clones and resolves all project dependencies defined in project.yml.
+
+#### 3. **Build the Project**
+   ```bash
+   hdlbuild build
+   ```
+   - Runs the full build process, including synthesis, implementation, and bitstream generation.
+
+   - To only synthesize the design:
+     ```bash
+     hdlbuild build synth
+     ```
+
+#### 4. **Run Testbenches**
+   ```bash
+   hdlbuild test <testbench_name>
+   ```
+   - Builds and runs the specified testbench.
+
+#### 5. **Clean Build Artifacts**
+   ```bash
+   hdlbuild clean
+   ```
+   - Removes build artifacts.
+
+   - To clean all generated files:
+     ```bash
+     hdlbuild clean all
+     ```
+
+---
+
