I use Obsidian to take note in class and then publish it online.

In my Database Course, there are many mathematical expressions in the subjects.
At first, we tried using regular characters to show math formulas, but that approach had some big limitations and was quite challenging to work with during classes, copying symbols from the internet. Like Ȼ e 3√y.

As the next step, we started using Quick LaTeX Obsidian to write mathematical expressions, and it's been a very good solution! However, we encountered difficulties converting LaTeX expressions to Markdown and publishing them accurately..

Describe the solution you'd like
Add support to math syntax like Obsidian does.

Using double dollar signs:

$$
\begin{vmatrix}a & b\\
c & d
\end{vmatrix}=ad-bc
$$

And inline math expression using single dollar, like $e^{2i\pi} = 1$.

Looking through the install script, it currently tries to install with /usr/local/bin.
Describe the solution you'd like
~/.local/bin should be defaulted to instead; it follows the XDG Base Directory Specification and it doesn't require administrator priviledges.

Additional context
If a systemwide installation is desired(the user does something like run with sudo or passes a commandline flag), I'd opt for something under opt/ rather in /usr/local/bin, as stuff under /usr is generally reserved for system installed packages with fedora/redhat and sundry
