+## Remove indentation before end token (or use `<<-` and indent with tabs).
+
+### Problematic code:
+
+```sh
+for f in *.png
+do
+  cat << EOF
+     <img src="$f" /><br/>
+  EOF
+done > index.html
+```
+
+### Correct code:
+
+```sh
+for f in *.png
+do
+  cat << EOF
+     <img src="$f" /><br/>
+EOF
+done > index.html
+```
+### Rationale:
+
+The here document delimiter will not be recognized if it is indented.
+
+You can fix it in one of two ways:
+
+1. Simply remove the indentation, even though this may break formatting.
+2. Use `<<-` instead of `<<`, and indent the script with tabs only (spaces will not be recognized).
+
+Removing the indentation is preferred, since the script won't suddenly break if the script is reformatted, copy-pasted, or saved with a different editor.
+
+### Exceptions:
+
+If the line was supposed to be a literal part of the here document, consider choosing a less ambiguous token.
