-Spectral parameterization is a fast, efficient, and physiologically-informed tool to parameterize neural power spectra.
+Spectral parameterization (`specparam`, formerly `fooof`) is a fast, efficient, and physiologically-informed tool to parameterize neural power spectra.
+
+WARNING: this Github repository has been updated to a major update / breaking change from the current release of the `fooof` module, and is no longer consistent with the `fooof` version of the code.
