First Open Source Projects from Bulgarian government

The Bulgarian Government open source the code of some projects paid by the state for very first time.
The open source code is on https://github.com/governmentbg/
This happens with the support of общество.бг (society.bg).
Why open source is so important for the government projects? Because people will have access to the final code government spends tax money for and all technical knowledge people could have look what exactly is done. Many people could see the source and give feedback improving the security and functionality of the code.
