 # Knowhere Python SDK
 
+[![PyPI version](https://img.shields.io/pypi/v/knowhere-python-sdk.svg)](https://pypi.org/project/knowhere-python-sdk/)
+
 Official Python SDK for the [Knowhere](https://knowhereto.ai) document parsing API.
 
 ## Installation
 
-```bash
+```sh
 pip install knowhere-python-sdk
 ```
 
 Or with [uv](https://docs.astral.sh/uv/):
 
-```bash
+```sh
 uv add knowhere-python-sdk
 ```
 
-## Quick Start
+## Usage
 
 ```python
 import knowhere
 
 client = knowhere.Knowhere(api_key="sk_...")
 
-# Parse a document from URL
 result = client.parse(url="https://example.com/report.pdf")
 
-print(result.statistics.total_chunks)  # 152
-print(result.full_markdown[:200])      # First 200 chars of full markdown

 for chunk in result.text_chunks:
     print(chunk.content[:80])
 ```
 
-### Parse a Local File
+While you can provide an `api_key` keyword argument, we recommend using [python-dotenv](https://pypi.org/project/python-dotenv/) to add `KNOWHERE_API_KEY="sk_..."` to your `.env` file so that your API key is not stored in source control.

+## Handling errors

+All errors inherit from `knowhere.KnowhereError`.

 ## Configuration
 
 The SDK reads configuration from constructor arguments, environment variables, or defaults (in that priority order):
