Check for open issues or open a fresh issue to start a discussion around a feature idea or a bug.\n2. Fork the [repository](https://github.com/stephane/modbusino/) on Github to start making your changes on another\n   branch.\n3. Send a pull request (of your small and atomic changes).\n4. Bug the maintainer if he's too busy to answer :)\n","funding_links":[],"categories":["Libraries"],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstephane%2Fmodbusino","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fstephane%2Fmodbusino","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstephane%2Fmodbusino/lists"}
