+name: Zcb
+long_name: Simple code-size saving instructions
+description: |
+  Zcb has simple code-size saving instructions which are easy to implement on all CPUs. 
+  All proposed encodings are currently reserved for all architectures, and have no conflicts with any existing extensions.
+  
+  The Zcb extension depends on the Zca extension.
+  
+  As shown on the individual instruction pages, many of the instructions in Zcb depend upon another extension being implemented. 
+  For example, c.mul is only implemented if M or Zmmul is implemented, and c.sext.b is only implemented if Zbb is implemented.
