+## Couldn't find 'fi' for this 'if'.
+
+### Problematic code:
+
+```sh
+if true
+then
+  echo "True"
+done
+```
+
+### Correct code:
+
+```sh
+if true
+then
+  echo "True"
+fi
+```
+### Rationale:
+
+ShellCheck has found an `if` statement that does not appear to have a matching terminating `fi`.
+
+This could be because it's missing entirely, or because the `if` statement was incorrectly terminated by a mismatched `done`, `esac`, `)` or similar. A companion warning [[SC1047]] is emitted at the point where ShellCheck expected the `fi`.
+
+Check that the `if` statement is completely and correctly terminated.
+
+### Exceptions:
+
+None
