Hi.

We use simple confluence pages for requirements documenting - create a page for each jira story and write requirements on it, put anchors on pages, link them to each other. 

It's very hard to get a requirements baseline this way or to determine behavior of the latest version of the product.  We want to integrate requirements management tool into our working process. I was surprise when found out that there is super-little information about these tools on the internet, youtube etc. 

What tool would we better consider? Is there a way to get some description of its features, try some trial access etc? It would be great to try the demo version of this tool before purchasing it.

thank you
