 There are two major ways that K3s is lighter weight than upstream Kubernetes:
 1. The memory footprint to run it is smaller
-1. The binary, which contains all the non-containerized components needed to run a cluster, is smaller
+2. The binary, which contains all the non-containerized components needed to run a cluster, is smaller
 
 The memory footprint is reduced primarily by running many components inside of a single process. This eliminates significant overhead that would otherwise be duplicated for each component.
