+  summary: 'Platform agnostic conda environment export'
+  description: |
+    An alternative to `conda env export` that helps create portable environment 
+    specifications with minimal number of packages. Resulting specification is 
+    similar to `conda env export --from-history`, but also includes packages 
+    that were installed using `pip`.
