Claper turns your presentations into an interactive, engaging and exciting experience. Claper has a two-sided mission. The first one is to help people presenting an idea or a message by giving them the opportunity to make their presentation unique and to have real-time feedback from their audience. The second one is to help each participant take their place, be an actor in the presentation, in the meeting, and to feel important and useful. In this step by step guide I will show you how to install Claper on your Synology NAS using Docker and Portainer.

💡Note: This guide works perfectly with the latest Claper v2.1.0 release.
