 Contributing Guide
 ==================
 
-Hello, and thank you so much for taking your time to contribute in any way to
-htop! There are many ways to contribute, and I'll try to list them below. The
-support from the free software community has been amazing over the years and
-it is the number one thing that keeps me going, maintaining and improving
-something that started as a tiny pet project back in 2004 and that nowadays is
-a piece of software used all over the world, in both reality [and
-fiction!](http://hisham.hm/htop/index.php?page=sightings). Cheers!
-
--- Hisham Muhammad
+Thank you so much for taking the time to contribute in to htop!
 
 Bug Reports
 -----------
 
 Bug reports should be posted in the [Github issue
-tracker](http://github.com/hishamhm/htop/issues). (I reply to them all, but I
-usually do it in batches! :) ) Bug reports are extremely important since it's
-impossible for me to test htop in every possible system, distribution and
-scenario. Your feedback is what keeps the tool stable and always improving!

 Pull Requests

+appreciated for support of platforms other than Linux.  If proposing new
 features, please be mindful that htop is a system tool that needs to keep a
-small footprint and perform well on systems under stress -- so unfortunately I
-can't accept every new feature proposed, as I need to keep the tool slim and
-maintainable. Great ideas backed by a PR are always carefully considered for
-inclusion, though! Also, PRs containing bug fixes and portability tweaks are a
-no-brainer, please send those in!

 Feature Requests
 ----------------
 
-Back when htop was hosted in SourceForge, there used to be separate Bug
-Tracker and Feature Request pages. These go all lumped together under "Issues"
-in Github, which is a bit confusing. For this reason, I close Feature Requests
-and file them with the [`feature
-request`](https://github.com/hishamhm/htop/issues?utf8=%E2%9C%93&q=is%3Aissue+label%3A%22feature+request%22+)
-label, where they remain accessible, but not mixed with actual bug reports.
-This doesn't mean I'm dismissing or ignoring feature requests right away! It's
-just an organizational issue (with Github, really!).
