+## Important: Do not use `\[ \]` or `$$ $$`
+
+The Math block already renders content in math mode.  
+Because of this, LaTeX display math delimiters should **not** be used:
+
+```
+\[ ... \]
+$$ ... $$
+```
+
+Using these delimiters will cause KaTeX to report parsing errors such as:
+
+`Can't use function '\' in math mode`
