Some miscreants are saying that radare2 is not documented, this is wrong.

The Book

The “radare book” was released together with radare 1.0, several years ago, so some of the examples/features may not be compatible with radare2.

You can read it online or download the PDF.

Recently, our tester in chief, maijin, started a project to update the radare book to create the radare2 book; feel free to contribute.

A book focused on practical case by monosource is also available : radare2-explorations

The API

The radare2 api (aka libr) is described in vapi files. Those files are translated by valaswig into swig interface files to generate the bindings for python, ruby, perl and others.

Those Vala vapi files are at the same time parsed by Valadoc to generate the online documentation.
