Question : Is it possible to use tikzcd code in MO posts?

There are information for drawing diagrams using AMScd

$\require{AMScd}$
\begin{CD}
A @>a>> B\\
@V b V V= @VV c V\\
C @>>d> D
\end{CD}


but could not find one for tikzcd

I want to compile following tikz code.

\begin{tikzcd}
&&\mathcal{H}_1\ar[dd,shift left]\ar[dd,shift right]\\
&
P\ar[dl,"\pi"']\ar[dr,"a_R"]
& \\[1.5em]
B & & \mathcal{H}_0
\end{tikzcd}

• Copy into a PDF, take a screenshot, select, trim, and so on, upload.

• That is really not easy. I tried for some questions which you can see from my recent question.. That is really time consuming which I would not prefer.. any other suggestions ?? @AsafKaragila Jul 1, 2018 at 15:03
• Nothing about using tikz is easy. Why should using tikz on MO be easier?

• @AsafKaragila I don’t have any preference for tikzcd or anything for that matter.. most of the questions asking for help in commutative diagrams code has this tikzcd so I am trying to get used to that.. Jul 1, 2018 at 16:57
