-Each has an easy command at the top for reproducing in the CLI.
+They are named similarly to [hledger check][]'s checks.
-Some have additional declarations to help with reproducing in Emacs with flycheck-hledger.
 
-hledger error messages are still pretty inconsistent. 
+In the CLI, execute them to see the error messages (`./showall`).
