 Comment 0: hey @lmhmhl, thanks for the offer! 💪 

we do have a few issues marked as [`good first issue`](https://github.com/reactor/reactor-netty/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc+label%3A%22good+first+issue%22) and [`help wanted`](https://github.com/reactor/reactor-netty/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc+label%3A%22help+wanted%22). The two labels overlap a bit, the first one should indicate an issue that is solvable with less deep knowledge of the project's internals.

Please make sure to read [CONTRIBUTING guidelines](https://github.com/reactor/reactor-netty/blob/master/CONTRIBUTING.md) first 👍 

Beforehand, consider also browsing the reference guides:
 - the reactor-core reference guide at https://projectreactor.io/docs/core/release/reference/
 - the reactor-netty reference guide at https://projectreactor.io/docs/netty/release/reference/
 Comment 1: Note that similar labels can be found in other projects, like reactor-core.

There isn't always a lot of entry-level issues these days, but we try to identify them so watch the labels if no issue currently makes a good candidate for you.
 Comment 2: @lmhmhl If you decide to contribute to some of the issues mentioned above just drop a comment to the particular issue.
