可以创建行内公式，例如：$\Gamma(n) = (n-1)!\quad\forall n\in\mathbb N$
或者块级公式，
$$ x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} $$
flow
st=>start: Start
e=>end: End
op1=>operation: My Operation
sub1=>subroutine: My Subroutine
cond=>condition: Yes or No?
io=>inputoutput: catch something...
st->op1->cond
cond(yes)->io->e
cond(no)->sub1(right)->op1
sequence
Alice->Bob: Hello Bob, how are you?
Note right of Bob: Bob thinks
Bob-->Alice: I am good thanks!
