+## Place shellcheck directives before commands, not after.
+
+### Problematic code:
+
+```sh
+var=1 # shellcheck disable=SC2034
+```
+
+### Correct code:
+
+```sh
+# shellcheck disable=SC2034
+var=1 
+```
+### Rationale:
+
+ShellCheck expects directives to come before the relevant command. They are not allowed after.
+
+### Exceptions:
+
+If this is not a directive and just a comment mentioning ShellCheck, please rewrite or capitalize:
+
+    var=1 # ShellCheck encourages lowercase variable names
