 # sgx-sdk-rs
 
-This is a fork of the [teaclave-sgx-sdk](https://github.com/apache/incubator-teaclave-sgx-sdk) project.
+Rust SDK for [Intel SGX (Software Guard Extensions)](https://github.com/intel/linux-sgx) - A collection of tools and libraries for building secure enclaves in Rust.
+
+## Features
+
+- **Rust SGX Libraries**: Core libraries for developing SGX enclaves
+- **cargo-sgx**: A Cargo subcommand that streamlines SGX enclave development by providing:
+  - Project initialization with templates (`cargo sgx init`)
+  - Automated enclave building command (`cargo sgx build`)
+  - Seamless integration with the Rust toolchain using custom target `x86_64-unknown-unknown-sgx`
+
+## Getting Started
+
+### Install cargo-sgx
+
+```bash
+cargo install --git https://github.com/datachainlab/sgx-sdk-rs --branch main cargo-sgx
+```
+
+Or install from local directory:
+
+```bash
+cargo install --path ./cargo-sgx
+```
+
+### Create Your First Enclave
+
+```bash
+cargo sgx init
+cd enclave
+cargo sgx build
+```
+
+## Project Structure
+
+- `sgx-*` - Core SGX libraries (types, ert, trts, tseal, urts, etc.)
+- [`cargo-sgx/`](cargo-sgx/) - Cargo subcommand for SGX development
+- [`sgx-build/`](sgx-build/) - Build utilities for SGX enclaves
+- [`unit-test/`](unit-test/) - Unit tests for core SGX libraries
+- [`samples/hello-rust/`](samples/hello-rust/) - Basic SGX enclave example
+
+## Documentation
+
+- [cargo-sgx README](cargo-sgx/README.md) - Learn about the cargo-sgx tool
+- [sgx-build README](sgx-build/README.md) - Learn about the sgx-build crate
+
+## Requirements
+
+- Rust nightly toolchain
+- Intel SGX SDK
+- Intel SGX Driver(only for Hardware Mode)
+
+## Acknowledgements
+
+This project is based on the excellent work done by the [Apache Teaclave SGX SDK](https://github.com/apache/incubator-teaclave-sgx-sdk/tree/1b1d03376056321441ef99716aa0888bd5ef19f7) project. We are grateful for their foundational contributions to the Rust SGX ecosystem.
