-    <h1>TruePolyglot</h1>
-Truepolyglot is polyglot file generator project.
-This means that the generated file is composed of several file formats. The same file can be opened as a ZIP file and as a PDF file for example.
-The idea of this project comes from work of <a href="https://github.com/corkami">Ange Albertini</a>, <a href="https://www.alchemistowl.org/pocorgtfo/pocorgtfo07.pdf">International Journal of Proof-of-Concept or Get The Fuck Out</a> and <a href="https://www.troopers.de/wp-content/uploads/2011/04/TR11_Wolf_OMG_PDF.pdf">Julia Wolf</a> that explain how we can build a polyglot file.<br>
-Polyglot file can be fastidious to build, even more if you want to respect correctly file format. That's why I decided to build a tool to generate them.<br>
-My main motivation was the technical challenge.
