Mike is looking for a dock for his MacBook Pro since it only has the one USB-C connector. Leo says that he uses one from Other World Computing. Apple has confused everything with USB-C because it can connect to Thunderbolt 3 or USB 3, and it really doesn't specify what works and what doesn't. On top of that, there's only one port.
Mike will want a dock that has Thunderbolt 3 support. The WireCutter has an article about the best USB-C adapters, cables, and hubs here. Leo also mentions Henge Docks, which makes a product called Stone. This can also double as a wedge to place the MacBook on.
