+## Don't put semicolons directly after 'then'.
+
+### Problematic code:
+
+```sh
+if true; then; echo "Hi"; fi
+```
+
+### Correct code:
+
+```sh
+if true; then echo "Hi"; fi
+```
+### Rationale:
+
+`then` keywords should not be followed by semicolons. It's not valid shell syntax.
+
+You can follow them directly with a line break or another command.
+
+### Exceptions:
+
+None
