TLDR;


From native dropdown


to UI Dropdown

After following the readme.md of the current project, and setting up the project to run locally, Jon Snow starts to read the source code.

Where is the Documentation?


I can't find your components docs.

You know nothing, Jon Snow

Jon snow starts to search for the dropdown component. After a few hours of investigation, he realizes that there's a dropdown in the 17th screen of the application

Can you show me how to navigate to the blade number 17 in the project?


The test environment is down and I can't find your demo application.

You know nothing, Jon Snow

After Coffee Time, the test environment is back and the team shows Jon Snow that he needs an ID to authenticate and be able to run the application locally.

I’ve finished my implementation, could you please review my code?

I’ve finished all acceptance criteria.

You know nothing, Jon Snow
