+  <strong>The official Python client for the <a href="https://codesphere.com/api/swagger-ui/">Codesphere API</a>.</strong>
+</p>
 
-## Overview
 
-The Codesphere Python SDK provides a convenient wrapper for the [Codesphere Public API](https://codesphere.com/api/swagger-ui/?ref=codesphere.ghost.io&anonymousId=K9iszev), allowing you to interact with all API resources from your Python applications.
 
-## Installation
+---
 
-You can install the SDK directly from PyPI using `pip` (or your favorite package manager like `uv`).
+## Installation
 
 ```bash
-pip install codesphere
+uv add codesphere
+```
+
+## Configuration
+
+Create a `.env` file in your project root:
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `CS_TOKEN` | API token (required) | – |
+| `CS_BASE_URL` | API base URL | `https://codesphere.com/api` |
+
+## Quick Start
+
+```python
+import asyncio
+from codesphere import CodesphereSDK
+
+async def main():
+    async with CodesphereSDK() as sdk:
+        teams = await sdk.teams.list()
+        for team in teams:
+            print(f"{team.name} (ID: {team.id})")
+
+asyncio.run(main())
 ```
 
-or
+## Usage
+
+### Teams
+
+```python
+teams = await sdk.teams.list()
+team = await sdk.teams.get(team_id=123)
+await team.delete()
+```
+
+### Workspaces
+
+```python
+workspaces = await sdk.workspaces.list(team_id=123)
+workspace = await sdk.workspaces.get(workspace_id=456)
+
+result = await workspace.execute_command("ls -la")
+print(result.output)
+
+await workspace.env_vars.set([{"name": "API_KEY", "value": "secret"}])
+env_vars = await workspace.env_vars.get()
+```
+
+### Domains
+
+```python
+team = await sdk.teams.get(team_id=123)
+domains = await team.domains.list()
+domain = await team.domains.create(name="api.example.com")
+```
+
+### Metadata
+
+```python
+datacenters = await sdk.metadata.list_datacenters()
+plans = await sdk.metadata.list_plans()
+images = await sdk.metadata.list_images()
+```
+
+## Development
 
 ```bash
-uv add codesphere
+git clone https://github.com/Datata1/codesphere-python.git
+cd codesphere-python
+uv sync --all-extras
+uv run pytest
