There is a guide available where you can learn what CATA is https://cata-1.gitbook.io/cata-docs/introduction/what-is-cata . You have to give credit to the team for creating such a nice and comprehensive guide. There aren't many projects that have such guides.
The team created the guide and then forget to develop the rest of the project, its really that simple. Because thats the only thing found on there website nothing like info about project development or anyother useful info.
