+# Documentation Generator
+
+This tool helps you generate consistent documentation for your CUDA kernel projects built with kernel-builder. It analyzes source files and build configuration to create structured Markdown documentation.
+
+## Features
+
+- Extracts documentation from CUDA, C++, and header files
+- Parses build configuration from build.toml
+- Identifies kernels and function definitions with their parameters
+- Generates Markdown documentation with a table of contents
+- Includes build settings and project information
+
+## Usage
+
+```bash
+# Generate documentation for a kernel project
+python scripts/gen-docs.py /path/to/your/kernel/project
+
+# Specify custom output directory (default is "docs")
+python scripts/gen-docs.py /path/to/your/kernel/project --output custom-docs
+```
+
+## Comment Format
+
+For best results, document your kernels and functions using the following format:
+
+```cpp
+/**
+ * This is a description of the kernel or function.
+ * 
+ * Any additional details about the implementation or usage can go here.
+ */
+__global__ void my_kernel(float* input, float* output, int size) {
+    // kernel implementation
+}
+```
+
+The generator will extract this documentation and include it in the generated files.
+
+## Output Structure
+
+The generated documentation includes:
+
+1. **Table of Contents** - Navigation for all documentation sections
+2. **Project Overview** - Basic information about the project (from build.toml if available)
+3. **Build Configuration** - Settings from build.toml including:
+   - Kernel definitions
+   - CUDA capabilities
+   - Source files
+   - Dependencies
+4. **API Documentation** - Documentation for each source file:
+   - Function and kernel signatures
+   - Parameter tables with types
+   - Documentation comments
+
+## Example
+
+Given a project with the following structure:
+
+```
+my_kernel/
+├── build.toml
+├── kernel.cu
+└── torch-ext/
+    └── ...
+```
+
+Running the documentation generator:
+
+```bash
+python scripts/gen-docs.py my_kernel
+```
+
+Will produce `my_kernel.md` in the `my_kernel/docs` directory.
