 Rusty-Kaspa/Rust bindings for Python, using [PyO3](https://pyo3.rs/v0.20.0/) and [Maturin](https://www.maturin.rs). The result is a Python package that exposes rusty-kaspa/rust source for use in Python programs.
 
 # Building from Source
-1. Ensure Python 3.8 or higher (`python --version`) is installed. [*TODO validate 3.8 or higher is correct*]. Python installers can be found on [python.org](https://www.python.org).
-2. `cd ./python` 
-3. Create Python virtual environment: `python -m venv env`
-4. Activate Python virtual env: 
-- Unix-based systems: `source env/bin/activate`
+1. Ensure Python 3.9 or higher (`python --version`) is installed.
+2. Clone Python SDK source: `git clone -b python  https://github.com/aspectron/rusty-kaspa.git`
+3. `cd rusty-kaspa` 
+4. `cd python` (Python SDK crate)
+5. Create Python virtual environment with `python -m venv env` or your preferred env tool.
+6. Activate Python virtual environment: 
+- Unix-like systems: `source env/bin/activate`
 - Windows: `env/scripts/activate.bat`
-5. Install `maturin` build tool: `pip install maturin`
+5. Install Maturin build tool: `pip install maturin`
 6. Build Python package with Maturin:
-- For local development, build and install in active Python virtual env: `maturin develop --release --features py-sdk`
-- To build source and built (wheel) distributions: `maturin build --release --strip --sdist --features py-sdk`
+- Build & install in current active virtual env: `maturin develop --release --features py-sdk`
+- Build source and built (wheel) distributions: `maturin build --release --strip --sdist --features py-sdk`. The resulting wheel (.whl file) location will be printed `Built wheel for CPython 3.x to <filepath>`. The `.whl` file can be copied to another location or machine and installed there with `pip install <.whl filepath>`
 
 # Usage from Python
-See Python files in `./python/examples`.
+
+The Python SDK module name is `kaspa`. The following example shows how to connect an RPC client to Kaspa's PNN (Public Node Network).
+
+```python
+import asyncio
+from kapsa import Resolver, RpcClient
+
+async def main():
+    resolver = Resolver()
+    client = RpcClient(resolver)
+    print(await client.get_server_info())
+
+if __name__ == "__main__":
+    asyncio.run(main())
+```
+
+More detailed examples can be found in `./examples`.
 
 # Project Layout
 The Python package `kaspa` is built from the `kaspa-python` crate, which is located at `./python`.
