Step 2 - you need to read a white paper carefully. Pay your attention to the idea, concept and realization
Step 3 - check out all social networks and blogs. If the project is alive there should be regular updates
Step 4 - you need to contact the team. The feedback is very important thing
Step 5 - join this project community (telegram chat or btctalk tread). There should be 24/7 communication
