 This is a fork of the [Havoc](https://github.com/furrtek/portapack-havoc/) firmware, which itself was a fork of the [PortaPack](https://github.com/sharebrained/portapack-hackrf) firmware, an add-on for the [HackRF](http://greatscottgadgets.com/hackrf/). A fork is a derivate, in this case one that has extra features and fixes when compared to the older versions.

 # Quick overview

@@ -18,42 +18,40 @@ If you are new to *HackRF+PortaPack+Mayhem*, there is an awesome introductory vi

 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.

-## Does it work on H1/H2 PortaPack?
+## What to buy?

-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/_9zbXMk), 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.
+:heavy_check_mark: A recommended one is this [PortaPack H2](https://s.click.aliexpress.com/e/_DmU7GQX) pack, that includes everything you need. Sadly, the people making the H2 never made the updated schematics available (against the terms of the license). 

-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).
+:heavy_check_mark: Another popular option is the clone of the [PortaPack H1](https://s.click.aliexpress.com/e/_Dkbqs2X).

-## Where is the latest firmware?
+:warning: Be cautious , *ask* the seller about compatibility with the latest releases. Look out for the description of the item, if they provide the firmware files for an older version or they have custom setup instructions, this means it might be **NOT compatible**, for example:

-The **latest (nightly) release** can be found [here](https://github.com/eried/portapack-mayhem/releases/).
+![image](https://user-images.githubusercontent.com/1091420/214579017-9ad970b9-0917-48f6-a550-588226d3f89b.png)

-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. 
+:warning: If it looks **too different**, this might mean that they are using their own recipe, check the [different models](https://github.com/eried/portapack-mayhem/wiki/PortaPack-Versions) in our wiki. For example all the H3 and clones of that version use their own version of the firmware. They do not contribute the changes back and eventually you will be left with a device that nobody maintains:

-## 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*.
+![image](https://user-images.githubusercontent.com/1091420/214581333-424900ee-26f8-4e96-be2f-69d8dc995ba9.png)

-## 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. 
+## Where is the latest version?

-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 [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
+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.

 ## How can I collaborate
 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-collaborate) with details.

 Consider that the hardware and firmware has been created and maintain by a [lot](https://github.com/mossmann/hackrf/graphs/contributors) of [people](https://github.com/eried/portapack-mayhem/graphs/contributors), so always try colaborating your time and effort first.
