Markdown extensions

Cloud Shell tutorials support Markdown extensions to expand the capability of the language.

Code block formatting

To create a code block in your tutorial, use backticks:

```
print("hello world")
```

Code blocks support syntax highlighting and have a button to copy the code to the clipboard.

You can change the way a code block is displayed by adding a class name after the first set of backticks. For example, to tell a code block to syntax highlight as Python, you can add py as a class:

```py
print("hello world")
```

Here are some other classes you can use to change how a code block is shown:

Class Effect
LANGUAGE_CLASS_NAME Change the syntax highlighting to a specified supported language.
none Don't apply syntax highlighting to the code block.
sh Format the code like terminal input. The code is prefixed by a $, and a button is shown on the block that copies the code to Cloud Shell when clicked.
terminal Format the code like terminal output. Identical to the none style, except it has no copy buttons on the code block.

Here are the supported language styles for syntax highlighting:
