+### Found a new bug?
 
 - First step is to check whether this is a new bug! We encourage you to search through the issues of the project in question **and** associated repos!
 
-- If you come up with nothing, **open a new issue with a clear title and description**, as much relevant information as possible: system configuration, code samples & steps to reproduce the problem.

 ### Sending a PR for Bug Fixes
 
-You fixed something! Great! We hope you logged it first :) Make sure though that you've covered the lateral thinking needed for a bug report, as described above, also in your implementation! If there any tests, make sure they all pass. If there are none, it means they're missing - so add them!

 ## New Features 🎉
 
 The golden rule is to Discuss First!
 
 - Before embarking on adding a new feature, suggest it first as an issue with the `enhancement` label and/or title - this will allow relevant people to pitch in
-- We'll now discuss your requirements and see how and if they fit within the Speckle ecosystem. 
-- The last step is to actually start writing code & submit a PR so we can follow along! 
-- All new features should, if and where possible, come with tests. We won't merge without!

 > Many clients may potentially have overlapping scopes, some features might already be in dev somewhere else, or might have been postponed to the next major release due to api instability in that area. For example, adding a delete stream button in the accounts panel in rhino: this feature was planned for speckle admin, and the whole functionality of the accounts panel in rhino is to be greatly reduced!
 
 ## Cosmetic Patches ✨
 
-Changes that are cosmetic in nature and do not add anything substantial to the stability or functionality of Speckle **will generally not be accepted**. 
+Changes that are cosmetic in nature and do not add anything substantial to the stability or functionality of Speckle **will generally not be accepted**.
 
 Why? However trivial the changes might seem, there might be subtle reasons for the original code to be as it is. Furthermore, there are a lot of potential hidden costs (that even maintainers themselves are not aware of fully!) and they eat up review time unncessarily.
 
-> **Examples**: modifying the colour of an UI element in one client may have a big hidden cost and need propagation in several other clients that implement a similar ui element. Changing the default port or specifiying `localhost` instead of `0.0.0.0` breaks cross-vm debugging and developing.

 ### Approach
 
 Provides an abstract `GH_AsyncComponent` which you can inherit from to scaffold your own async component. There's more info in the [blogpost](https://speckle.systems/blog/async-gh/) on how to go about it.
 
-Even better, there's a [sample component that shows how an implementation could look like](https://github.com/specklesystems/GrasshopperAsyncComponent/tree/main/GrasshopperAsyncComponent/SampleImplementations)! There's two components in that folder:
-- The Useless Spinner: does no meaningfull CPU work, just keeps a thread busy with SpinWait()
-- The N-th Prime Calculator: can actually spin your computer's fans quite a bit (for numbers > 100.000) 
+> #### Checkout the sample implementation!
