Features Math, Diagrams and Flowcharts

#Math

TeX expressions are rendered via KaTex.

c = \\pm\\sqrt{a^2 + b^2}\\in\\RR

```tex
c = \\pm\\sqrt{a^2 + b^2}\\in\\RR
```

x = a_0 + \cfrac{1}{a_1 + \cfrac{1}{a_2 + \cfrac{1}{a_3+\cdots}}} 

```tex
x = a_0 + \cfrac{1}{a_1 + \cfrac{1}{a_2 + \cfrac{1}{a_3+\cdots}}} 
```

#Diagrams and Flowcharts

You can render Diagrams and Flowcharts using mermaid

#Flow

```mermaid
graph TD
A[Hard] -->|Text| B(Round)
B --> C{Decision}
C -->|One| D[Result 1]
C -->|Two| E[Result 2]
```

#Sequence

```mermaid
sequenceDiagram
Alice->>John: Hello John, how are you?
loop Healthcheck
    John->>John: Fight against hypochondria
end
Note right of John: Rational thoughts!
John-->>Alice: Great!
