-## FAQ
+# Quick overview

-The intention of the current repository is to try to get all the latest features and cleanest documentation for them, embracing any colaboration. To clarify any basic question, please read the following common ones:
+If you are new to *HackRF+PortaPack+Mayhem*, there is an awesome introductory video by [Tech Minds](https://www.youtube.com/channel/UC9a8Z6Sp6eb2s3O79pX5Zvg) available:

-### Does it work on H1/H2 PortaPack?
+[![Setup and overview](https://img.youtube.com/vi/kjFB58Y1TAo/0.jpg)](https://www.youtube.com/watch?v=kjFB58Y1TAo)

-Yes, those are the [same](https://github.com/eried/portapack-mayhem/wiki/First-steps). The one I am using to test all changes is this [Portapack H2+HackRF+battery](https://s.click.aliexpress.com/e/_dSMPvNo), which is a clone that includes everything you need. Sadly, the people making the H2 never published the updated PCB, so it is not "optimal" for the community.
+# Frequently Asked Questions

-### Where is the latest firmware?
+This repository expands upon the previous work by many people and aims to constantly add new features, bugfixes and generate documentation to make further development easier.  [Collaboration](https://github.com/eried/portapack-mayhem/wiki/How-to-collaborate) is always welcomed and appreciated.

-The current stable release is on the [Release](https://github.com/eried/portapack-mayhem/releases/latest) page. Follow the instructions you can find in the release description. 
+## Does it work on H1/H2 PortaPack?

-There is also [nightly builds](https://github.com/eried/portapack-mayhem/releases/tag/nightly) generated frequently, but these may contain incomplete functionality.
+Yes, both devices are the [same](https://github.com/eried/portapack-mayhem/wiki/First-steps). The one I am using to test all changes is this [PortaPack H2+HackRF+battery](https://s.click.aliexpress.com/e/_dZ7lA96), which is a kit that includes everything you need. Sadly, the people making the H2 never made the updated schematics available, which is not ideal (and goes against the terms of the license). Most members of the community are using a clone of the [PortaPack H1+HackRF+metal case](https://s.click.aliexpress.com/e/_dS6liw4), which does not include any battery functionality, but it is a cheaper alternative.

-### Is this the newest firmware for my PortaPack? 
-Probably **YES**.
+To support the people behind the hardware, please buy a genuine [HackRF](https://greatscottgadgets.com/hackrf/) and [PortaPack](https://store.sharebrained.com/products/portapack-for-hackrf-one-kit).

-### Which one is actually the newest?
+## Where is the latest firmware?
+
+The current stable release is on the [![GitHub release (latest by date)](https://img.shields.io/github/v/release/eried/portapack-mayhem?label=Releases&style=social)](https://github.com/eried/portapack-mayhem/releases/latest) page. Follow the instructions you can find in the release description. There is also [nightly builds](https://github.com/eried/portapack-mayhem/releases/tag/nightly) generated periodically, which include the latest commits, but they may contain incomplete or buggy functionality.
+
+## Is this the newest firmware for my PortaPack? 
+Most probably: **YES**. *If you find new features somewhere else, please [suggest](https://github.com/eried/portapack-mayhem/issues/new/choose) them*.
+
+## Which one is actually the newest?
 There is a lot of confusion of which is the latest version because no old version used any actual "version number". Additionally, since the files were distributed on facebook groups, github issue links and similar temporal sources, then there was no central location for them. 

 This fork (**Mayhem**) uses *major.minor.release* [semantic versioning](https://en.wikipedia.org/wiki/Software_versioning), so you can always compare your current version with the latest from [Releases](https://github.com/eried/portapack-mayhem/releases/latest).

-### What about Havoc/GridRF/jamesshao8/jboone's?
-* jboone's PortaPack: the [vainilla](https://en.wikipedia.org/wiki/Vanilla_software) experience
-* Havoc: It was the most popular fork of jboone's PortaPack, right now is readonly so it is not being developed
-* jamesshao8: He keeps his own version of the fork, while not attached as a fork to anything
+## What about Havoc/GridRF/jamesshao8/jboone's?
+* jboone's PortaPack: the [vanilla](https://en.wikipedia.org/wiki/Vanilla_software) experience
+* Havoc: It was the most popular fork of jboone's PortaPack, currrently, it is not being maintained nor updated
+* jamesshao8: He keeps his own version of the fork, while not attached as a fork to anything. Latest functions do not follow the license and are not being published with source code, so keep this in mind
 * GridRF: They sell PortaPack clones with their own firmware based on a old version, which has no sourcecode available

-### How can I colaborate
-You can write [documentation](https://github.com/eried/portapack-mayhem/wiki), fix bugs and [answer issues](https://github.com/eried/portapack-mayhem/issues) or add new functionality. Please check the following [guide](https://github.com/eried/portapack-mayhem/wiki/How-to-colaborate) with details.
