Hi Humppa,
It's quite an enjoyable journey to get this piece of wonderful technology started.
In case you still want to proceed with this quest...
1. Make sure you don't just download the latest version but download version that matches your Oak Core version release(will get some of the dependencies auto resolved)
2. Create a mini maven project with the library and all the dependencies that this bundle needs and that are not already exposed by your AEM installation.
3. Now you have your bundle successfully running and you can proceed with the next steps.
Regards,
Peter
