Overview
Trello is a small but beautiful product that requires no special in-depth knowledge for administrators or users, and works out of the box.
It was acquired by Atlassian in 2017, although there are more than a dozen competing products in the same industry such as Monday, Asana, Airtable, etc. Although it is supported by powerUP, there is a strong homogeneity in the main functions, walking in the jungle, it is still very necessary to rely on Atlassian's strong ecology, as shown below by the lovely Genie Turtle covered by the water arrow turtle.

This article briefly introduces Trello basics, advanced features, experiences, and common external integrations, with the hope that Trello will become a faithful steward for your daily work and lightweight management.
