Mathematical Equations such as $\int_{\infty}^{-\infty} x^2 dx$ can be placed inline with the text. Alternatively, it can be used as a block such as below.

\begin{aligned} y & = x^2 + 2x + 1 \\ & = (x+1)(x+1) \\ & = (x+1)^2 \end{aligned}

-2 \left|x - \left( \frac{n-1}{2} \right) \right| + n

RSS Feed

I used Gatsby to create an RSS Feed, containing a standardized format of my blog. This can be easily parsed and used in applications, and I have a project planned using it in the future.
