Attend Technical Meetings
Our EdgeX technical and marketing working groups meet, typically, once a week. These meetings are held by conference call and are open to the public. In these working group meetings, the technical work of the project is organized, design and architecture topics are discussed and decided upon, and marketing efforts are orchestrated.
