+
+Python library for [czv](https://github.com/rzmk/czv). czv is a library of utility functions for CSV-related data engineering and analysis tasks.
+
+## Installation and example
+
+```bash
+pip install czv
+```
+
+```python
+import czv
+
+data = """fruits,price

+banana,3.00
+strawberry,1.50"""
+
+output = czv.row_count(data, False)
+

+
+## Development
+
+You'll need to have [maturin](https://github.com/PyO3/maturin/) and [uv](https://github.com/astral-sh/uv) installed. Set up a local virtual environment in the `czv-python` folder by running:
+
+```bash
+uv venv
+```
+
+Make sure to activate the virtual environment (instructions should be provided in your terminal after running the previous command).
+
+Once you've activated the virtual environment, install dependencies by running:
+
+```bash
+uv pip install -r requirements.txt
+```
+
+### Build package in local environment
+
+```bash
+maturin develop --uv --release
+```
+
+### Run tests
+
+```bash
+pytest
+```
