-gotcha: inmemory-cache in Go (Golang) with customizable algorithm
+# [DEPRECATED] gotcha
 
+> Hi all, this library is no longer maintained. I don't see any usecase when to use this. Caching logic is a critical and complex problem. There are a lot of caching solutions that you can try, including this library. I find it hard to maintain this library since I don't use it extensively. Thanks for all the support and contributions so far. You can find me at https://imantumorang.com if you later need a similar library that we can collaborate on together.
