+Thanks for taking the time to draft up an issue for Axon Framework' Reactor Extension!
+Prior to starting off, please read the following:
+
+## Usage Questions
+
+If you are having difficulty using Axon Framework' Reactor Extension,
+ please consider to check Axon's Reference Guide first if it answers your question: https://docs.axoniq.io/reference-guide/extensions/reactor
+
+When the Reference Guide does no cover the specific question you have, take the following into account:
+- GitHub is *not* intended for usages questions, instead:
+- Drop a questions on AxonIQ's forum: https://discuss.axoniq.io/
+- Or place a new question on StackOverflow, using the `axon` tag.
+
+## Reporting an bug, feature or enhancement
+
+Prior to filing an issue, please verify that it's not already reported by someone else.
+After that's done, your issue will typically fall under one of the following options:
+
+1. It's a `bug`
+2. It's a `feature` request
+3. It's an `enhancement` request
+
+It is recommended that for either of the three you use one of the prepared issue template.
+You can find all three of them [here](https://github.com/AxonFramework/extension-reactor/issues/new/choose). 
+
+## None of the above fit!
+
+If you have encountered a use case which is not a question, nor a feature request, feel free to draft your scenario below.
