+
+Official Convilyn client SDK — file conversion, agentic workflows, and a community library for reusable AI workflows.
+
+Convilyn helps people turn repeated AI-assisted work into workflows that can be run again, shared, and improved. It is part of the CoreNovus vision for practical AI workflows across cloud services, local machines, AI PCs, edge devices, and future IoT environments.

+
+## What is Convilyn?
+
+Convilyn is an open source Python SDK for building with free file conversion tools and basic AI workflow capabilities.
+
+Its main value is helping people use the computing resources they already have — such as local machines, AI PCs, and edge devices — to run practical AI workflows without depending entirely on paid cloud services.
+
+## Who is this for?
+
+Convilyn is for:
+
+- Developers building reusable AI workflow components
+- People working with file conversion and automation
+- Builders experimenting with local-first AI workflows
+- Communities that want open, practical AI tooling
+- Contributors who want to help make AI workflows easier to use and share
+
+## Install
+
+```bash
+pip install convilyn
+```
+
+## Quickstart
+
+See **[docs/QUICKSTART.md](docs/QUICKSTART.md)** and the full docs at:
+
+[https://docs.convilyn.corenovus.com](https://docs.convilyn.corenovus.com)
+
+## Community
+
+Convilyn is maintained by CoreNovus, an independent developer team building open source tools for reusable AI workflows.
+
+We welcome contributions from people who want to help improve documentation, examples, tests, file conversion workflows, local-first AI workflows, and developer experience.
+
+A useful workflow should not disappear after one conversation. It should become something others can learn from, adapt, and run in their own context.

+## Project direction
+
+CoreNovus is building toward a world where AI workflows can move beyond one-time chat sessions.
+
+Convilyn focuses on the client SDK and community-facing workflow building blocks. The broader CoreNovus ecosystem aims to make workflows easier to create, save, reuse, share, and eventually run across cloud, local, and real-world environments.
