+%description
+Fast, reliable, and secure dependency management. Yarn: Fast,
+reliable, and secure dependency management.
+
+Fast: Yarn caches every package it downloads so it never needs to
+again. It also parallelizes operations to maximize resource
+utilization so install times are faster than ever.
+
+Reliable: Using a detailed, but concise, lockfile format, and a
+deterministic algorithm for installs, Yarn is able to guarantee that
+an install that worked on one system will work exactly the same way on
+any other system.
+
+Secure: Yarn uses checksums to verify the integrity of every installed
+package before its code is executed.
