Hi, Michal,

You can escape backticks using a different number of backticks as a wrapper=
. Examples:

1.

``There is a literal backtick (`) here.``

We're using two backstick as wrapper of one backtick.

2. Using Rowan example:


````php
$markdown=3D```
PHP has lots of ways to write strings: =20
```
$example =3D 'hello'; =20
$example =3D "hello"; =20
$example =3D <<<EXAMPLE =20
hello =20
EXAMPLE; =20
$example =3D <<<EXAMPLE =20
hello =20
EXAMPLE; =20
```
```
````

Live example: https://github.com/manuelcanga/RFC/blob/master/README.md

This works due to use four backticks as wrapper of three backticks.

Although these examples work generally, with some Markdown  parser can that=
  these doesn't work.

Maybe other syntax could be used, but I don't know which. In javascript onl=
y a backtick is used: https://developers.google.com/web/updates/2015/01/ES6=
-Template-Strings . But in PHP this is used as eval.
