 Requirements
 ------------
 
-Radon will run from **Python 2.7** to **Python 3.12** (except Python versions
-from 3.0 to 3.3) with a single code base and without the need of tools like
-2to3 or six. It can also run on **PyPy** without any problems (currently PyPy
-3.5 v7.3.1 is used in tests).
+Radon will run with **Python versions 3.3 to 3.13**; and through
+**PyPy** (currently PyPy 3.5 v7.3.1 is used in tests).
 
 Radon depends on as few packages as possible. Currently only `mando` is
 strictly required (for the CLI interface). `colorama` is also listed as a
 dependency but if Radon cannot import it, the output simply will not be
 colored.
 
 **Note**:
-**Python 2.6** was supported until version 1.5.0. Starting from version 2.0, it
-is not supported anymore.
+**Python 2** support was dropped in v6.0.0.
