About this website
LibFlow started as a personal website to organize notes, documents and papers on GNU/Linux, Programming, Maths and Physics. After we began sharing links with friends, we decided to allow everybody freely upload what they considered interesting for other people to read. Here we share free documentation only!

Special thanks go to all people contributing to the free and open source community. LibFlow is made possible by the work of Creative Commons, FSF, GNU/Linux, PDF.js, Freebase, jQuery, pdf2htmlEX, Fontforge, Poppler
