+  summary: A Python-embedded modeling language for convex optimization problems
+  description: |
+    CVXPY is a Python-embedded modeling language for convex optimization
+    problems. It allows you to express your problem in a natural way that
+    follows the math, rather than in the restrictive standard form required
+    by solvers.
