!!! note "Using Documenter adjustment"

Math markup using ``\LaTeX`` in Markdown may be done with different delimiters. There are paired dollar signs (or double dollar signs); paired `\(` and `\)` (or `\[`, `\]`) delimiters; double backticks (which require no escaping); or even `math` flavors for triple backtick blocks. When displaying ``\LaTeX`` in HTML, the paired parentheses are used. **However** with `Documenter` paired dollar signs are needed for markup used by `QuizQuestions`.
As of `v"0.3.21"`, placing the line `ENV["QQ_LaTeX_dollar_delimiters"] = true` in `make.jl` will instruct that. This package documentation illustrates.
