 Before you submit an issue, please search the issue tracker, maybe an issue for your problem already exists and the discussion might inform you of workarounds readily available.
 
-We want to fix all the issues as soon as possible, but before fixing a bug we need to reproduce and confirm it. In order to reproduce bugs we will systematically ask you to provide a minimal reproduction scenario using a repository or [Gist](https://gist.github.com/). Having a live, reproducible scenario gives us wealth of important information without going back & forth to you with additional questions like:
-
-- version of NestJS used
-- 3rd-party libraries and their versions
-- and most importantly - a use-case that fails
-
-<!--
-// TODO we need to create a playground, similar to plunkr
-
-A minimal reproduce scenario using a repository or Gist allows us to quickly confirm a bug (or point out coding problem) as well as confirm that we are fixing the right problem. If neither of these are not a suitable way to demonstrate the problem (for example for issues related to our npm packaging), please create a standalone git repository demonstrating the problem. -->
-
-<!-- We will be insisting on a minimal reproduce scenario in order to save maintainers time and ultimately be able to fix more bugs. Interestingly, from our experience users often find coding problems themselves while preparing a minimal plunk. We understand that sometimes it might be hard to extract essentials bits of code from a larger code-base but we really need to isolate the problem before we can fix it. -->
-
 Unfortunately, we are not able to investigate / fix bugs without a minimal reproduction, so if we don't hear back from you we are going to close an issue that don't have enough info to be reproduced.
