Kangaroos algorithm for ECDLP: looking for resources

Does anyone know where I can get some in-depth papers and tutorials on the Kangaroos algorithm for ECDLP? I'm still trying to wrap my head around the specifics of the algorithm. It looks like it's not connected to elliptic curve encryption (ECC) from what I've seen. Really hoping to find some solid info to help me learn more. Thanks!

I did a couple of searches on the Internet, and I think the resources below could provide useful information for you. Additional to the one posted by iceland2k14. https://github.com/RetiredC/RCKangaroo https://github.com/RetiredC/Kang-1 The one in charge of that is posting here in Bitcointalk. https://bitcointalk.org/index.php?topic=5517607.0
