Sure, so I was working for a retail giant of Euro and we were having a project to enhance e-commerce application. So we use Jira to document requirements so every brand manager has their own requirement for their own geographies. So we used to have a call with those stakeholders, we were used to understand their requirement and then we used to document them in Jira and send it back for mince approvals. So Jira was our source of documentation, in Agile we used to have user story, we did not documented long documents like function requirement document, specification requirement document and so on. So that's how we documented our requirements.
