-# Hyperledger Fabric Chaincode shim and Contract API for Python
-
-This repository provides the Python implementation of Hyperledger Fabric chaincode shim and contract API. Chaincodes (smart contracts) can be written in Python to run inside Hyperledger Fabric peers.
+This is a Python based implementation of Hyperledger Fabric chaincode shim and contract
+API, which enables development of smart contracts using the Python language. Chaincodes
+(smart contracts) written in Python run inside Hyperledger Fabric peers.
 
 ## Documentation
 
-- API documentation: https://hyperledger.github.io/fabric-chaincode-python/
-- Full Documentation on Hyperledger Fabric: https://hyperledger-fabric.readthedocs.io/
-- Samples repository: https://github.com/hyperledger/fabric-samples
-- Quick-start tutorial: TUTORIAL.md
+- [API documentation](https://hyperledger.github.io/fabric-chaincode-python/)
+- [Full Hyperledger Fabric documentation](https://hyperledger-fabric.readthedocs.io/)
+- [Samples repository](https://github.com/hyperledger/fabric-samples)

+## Project structure
+
+```
+src/
+├── fabric_contract_api/   Python Contract API
+└── fabric_shim/           Python chaincode shim (Fabric 2.x)
+```
+
+- **fabric_contract_api** - Contains the Python contract API used to write smart contracts with the high-level contract programming model.
+- **fabric_shim** - Contains the Python classes that implement the chaincode shim API and the way to communicate with Fabric peers.
 
-## Compatibility
+## Building and testing
 
-For details on what Python versions and Hyperledger Fabric versions can be used, see the [COMPATIBILITY.md](COMPATIBILITY.md).
+Make sure you have the following prereqs installed:
 
-## npm Shrinkwrap
+- [Python](https://www.python.org/) 3.11 or later
+- [pip](https://pip.pypa.io/en/stable/)
 
-Strongly recommended to create a `requirements.txt` file after testing and before putting your contract into production.
+Create a virtual environment and install the development dependencies:
+
+```
+python3 -m venv .venv
+source .venv/bin/activate
+pip install -e . -r requirements-dev.txt
+```
+
+Run the unit tests:
+
+```
+pytest tests/
+```

+# Security Policy
+
+We take the security of `fabric-chaincode-python` seriously. This document describes how to report a vulnerability and how we handle it.
+
+## Reporting a Vulnerability
+
+Please **do not** open a public issue for security vulnerabilities. Instead, report them privately so they can be addressed before disclosure.
+
+To report a vulnerability, contact the project maintainers directly. See [MAINTAINERS.md](MAINTAINERS.md) for contact information.
+
+Vulnerabilities in the broader Hyperledger Fabric ecosystem should be reported in accordance with the
+[Hyperledger Fabric security policy](https://github.com/hyperledger/fabric/blob/main/SECURITY.md).
+
+## Responsible Disclosure
+
+We follow a coordinated disclosure process:
+
+1. You report the vulnerability privately to the maintainers.
+2. The maintainers acknowledge receipt and begin an assessment.
+3. A fix is prepared, tested, and released.
+4. The vulnerability is disclosed publicly only after the fix is available.
+
+We ask that you keep the details confidential until a fix has been released.
+
+## Scope
+
+- The Python chaincode shim and contract API implemented in this repository (`src/`).
+- Supporting build and test tooling under `scripts/` and `tests/`.
+
+Third-party dependencies are outside this repository's direct control; please report issues with them to their respective projects.
+
+## Supported Versions
+
+Security fixes are provided for the latest stable release and, where feasible, recent releases still under active maintenance. See [RELEASING.md](RELEASING.md) for the release and support policy.
+
+## Thanks
+
+We appreciate responsible security researchers who help us improve the security of this project.
