There’s even syntax highlighting for code samples. Neat.
# Headers
res['Set-Cookie'] # => String
res.get_fields('set-cookie') # => Array
res.to_hash['set-cookie'] # => Array
puts "Headers: #{res.to_hash.inspect}"
This is where an opinionated hot take might begin. Maybe I’ll get to it
someday. Static websites are pretty cool. They take a lot of the worries out of
the process, I’ll tell you that much. When you don’t have to worry about
building and maintaining dynamic websites, you’re freed up to focus on the
content. Or think about other crazy things, or just tinker with different ways
to generate your own unique identifiers like 9kQr9bN.
How about images?
Neat! Now how about a PlantUML diagram?
And tables. We really can’t forget about the presentation of tabular data.

Math Formatting Examples
Here are a few varied samples of what MathJax can render.
Triple integral (volume of a sphere):
\[\iiint_V dV = \int_0^{2\pi} \int_0^\pi \int_0^R r^2 \sin\phi \, dr \, d\phi \, d\theta = \frac{4}{3} \pi R^3\]Piecewise function:
\[f(x) = \begin{cases} x^2, & x \geq 0 \\ -x^2, & x < 0 \end{cases}\]Matrix with inline reference:
The inertia tensor $\mathbf{I}$ for a rigid body is a $3 \times 3$ matrix:
\[\mathbf{I} = \begin{pmatrix} I_{xx} & I_{xy} & I_{xz} \\ I_{yx} & I_{yy} & I_{yz} \\ I_{zx} & I_{zy} & I_{zz} \end{pmatrix}\]where $I_{xx} = \sum_i m_i (y_i^2 + z_i^2)$ and so on.
Summation identity:
\[\sum_{k=1}^n k^3 = \left( \sum_{k=1}^n k \right)^2 = \frac{n^2 (n+1)^2}{4}\]Inline delimiters that scale:
\[\left( \frac{1}{1 + \frac{1}{x}} \right)^{\!n} \quad\text{vs}\quad \left[ \int_0^\infty e^{-t^2} dt \right]^2\]
