I, one of the Polkadot portuguese language senior ambassadors, Luis, am asking for a tip to Artur, also a Polkadot portuguese language ambassador, for a video of 35 minutes and 40 seconds explaining in portuguese step by step, how to create and maintain a node on Polkadot/Kusama, as well as presenting the best practices.
The video is helpful on educating those interested in contributing to Polkadot/Kusama decentralization and become active members of the ecosystem. His address was added to the video description to verify authorship
