@fu050409 Hi, I would like to work on this issue. I will create the LICENSE file (can we find it here) and also I will:

• Add the license notices to the program (at the beginning of each source file as a comment). The modified files will be in src and src-tauri;
• Add the license notices:
  • GitHub repository link
  • Contact information (email if you want, or GitHub issue eventually)

@AndreVale69 Thanks, contributions are very welcome!

Nice! I'm going to fork the repository and start working in it.

@fu050409 The author of the repository is Association of Computing Machinery affiliated SWPU, is that correct? I assume so because the repository is under that organization.

@AndreVale69 Yes, for sure :-D
