There is plenty of information on the website. Start by looking at the features and screenshots, then have a look through some of the guides. You can download the desktop version for free, so try that out to see if it is compatible with your needs.
If you’ve done all of the above and you still have questions, try searching this forum. There is a good chance your questions have been asked by someone else already, and answered.
If you still have questions, then post a topic in the forum with a very clear and specific summary of what you would like to know. Nobody is going to want to spend their time on here listing all the features of Manager or explaining the basics, as all of that information is readily available on the website.
