+# Summary
+
+Carl is a likelihood-free inference toolbox for Python. Its goal is
+to provide tools to support inference in the likelihood-free setup,
+including density ratio estimation algorithms, parameterized supervised
+learning and calibration procedures.
+
+Methodological details regarding likelihood-free inference with calibrated
+classifiers can be found in the companion paper [@Cranmer:2015-llr].
+
+Future development aims at providing further density ratio estimation
+algorithms, along with alternative algorithms for the likelihood-free setup,
+such as ABC.
