Thanks Saminda for a nice overview. Udara, you will find this situation not so uncommon with many open source projects you will stumble upon. Four of your friends to work through these voids are website [1], wiki [2], jira [3], mailing list archives [4]. Note that mailing list archives are searchable in google and other search engines. But all these will frequently lie to you. So you want to instead trust a best friend [5] whom can always trust and will never lie.
