-**COULDN'T FIND THE END OF THE HERE DOC.** The starting Here tag must match the closing Here tag. 
+## Couldn't find end token `EOF' in the here document.
+
+### Problematic code:
+
+```sh
+cat << EOF
+  Hello World
+```
+
+### Correct code:
+
+```sh
+cat << EOF
+  Hello World
+EOF
+```
+### Rationale:
+
+The `<<` here document (aka heredoc) was not properly terminated. The terminating token needs to be on a separate line without indenting (or indented with tabs only when using `<<-`).
+
+Note that you can not put here documents in one liners. For such use cases, use a `<<<` here string:
+
+    cat << EOF  hello world  EOF   # Wrong: data and terminator can not be on the same line
+    cat <<< "hello world"          # Correct
+
+### Exceptions:
