+## Was this intended as a comment? Use `#` in sh.
+
+### Problematic code:
+
+```C
+// This is a comment.
+/* This too. */
+```
+
+### Correct code:
+
+```sh
+# This is a comment.
+# This too.
+```
+### Rationale:
+
+ShellCheck found what appears to be a C-style comment, a line starting with `//` or `/*`.
+
+In Bourne based shell scripts, the comment character is `#`
+
+### Exceptions:
+
+None.
