+## This shebang was unrecognized. Note that ShellCheck only handles sh/bash/dash/ksh.
+
+### Problematic code:
+
+```sh
+#!/bin/mywrapper
+echo "Hello World"
+```
+
+### Correct code:
+
+```sh
+#!/bin/mywrapper
+# shellcheck shell=bash
+echo "Hello World"
+```
+
+### Rationale:
+
+You have specified a shebang that ShellCheck doesn't recognize. This can be due to invoking the script via a wrapper, specifying a dummy like `#!/bin/false` to prevent execution, or writing a script for a non-Bourne shell or tool.
+
+If this really is a sh/bash/dash/ksh script, please add a `shell` directive after the shebang to tell ShellCheck how to interpret the script, as in the example. You can also specify the shell with the `-s` flag. 
+
+If this is a script in some other language, like `#!/bin/sed` for a `sed` script, then sorry -- ShellCheck does not support `sed`, `awk`, `expect` scripts. It only supports Bourne style shell scripts. 
+
+### Exceptions:
+
+None.
