+## 'local' is only valid in functions.
+
+### Problematic code:
+
+```sh
+local foo=bar
+echo "$foo"
+```
+
+### Correct code:
+
+```sh
+foo=bar
+echo "$foo"
+```
+### Rationale:
+
+In Bash, `local` can only be used in functions. In other contexts, it's an error.
+
+### Exceptions:
+
+It's possible to source files containing `local` from a function context but not from any other context. This is not good practice, but in these cases you can [[ignore]] this error.
