Codeforces is a site where there are algorithmic problems.
They can be solved in competition or whenever.
I solve all theses problems in Java, but the language is not imposed.
I use Competitive-dl to download the subject into pdf.
I use TTR PDF To JPG3 to convert each pdf.
I have implemented readmeMaker.jar to automatically create readme files. (source code)
You can directly launch it or you can use the command :
java -jar readmeMaker.jar
It will show the list of the readme files created.
If you want to overwrite them, use the command :
java -jar readmeMaker.jar -f
