My first attempt to modding (in a very basic approach). The premiere of Cyberpunk 2077 is an opportunity for me to learn something new and I decided to start with a manager. This application was written in C♯. It only uses the core libraries from Microsoft (plus LZMA, 7-ZIP and SevenZipSharp for unpacking).
Often times, good tools written by good programmers aren't pretty. That's why I, as a bad programmer, chose one of the main goals to make the manager looks nice and only later functional. Therefore, you may encounter a lot of bugs.
The application was written in .NET 5 WPF C♯ technology. It is distributed as self-contained or framework-depend. Therefore, you will find two identical files, one approximately 20MB in weight and one 100MB. Second one has all the libraries inside, thus you don't need to install anything extra.

Previously, the modding community quickly adapted the basic rules for creating mods for The Witcher 3.
So please, if you create mods and want to make things easier for me - and users, follow these tips:
- Name your main archive mod{MyName}-{v.1.0.0}.zip (rembember that source code of ZIP & 7-Zip is freely available, RAR is not)
- If your mod adds a modification, add its folder to the mods folder inside the archive root path. (start folder name with mod{MyName})
- If your mod adds a DLC, add its folder to the dlc folder inside the archive root path. (start folder name with dlc{MyName})
- If your mod adds a bin files, add its files to the bin folder inside the archive root path. (drop files directly into this folder)
- If your mod adds a content files, add its files to the content folder inside the archive root path. (drop files directly into this folder)
A little extra from me, if you want to send additional information to the manager and import all data immediately - add to the root of the archive folder file: modmanager.json
