+## Decompilers
+
+### [Ghidra Decompiler](https://github.com/thestr4ng3r/r2ghidra-dec)
+This is an integration of the Ghidra decompiler for Cutter and radare2. It is solely based on the decompiler part of Ghidra, which is written entirely in C++, so neither Ghidra itself nor JAVA are required at all and the plugin can be built self-contained.
+
+Due to its quality, the ghidra decompiler plugin is shipped by default in Cutter releases.

+### [r2dec](https://github.com/wargio/r2dec-js)
+r2dec converts the assembly of a function to a Pseudo-C code. Cutter integrates r2dec by default.
