How do you add a code block to a pull request description on github?

Question

Typing HTML does not work when I want to show a Code Block.

Answer 1

As stated in the documentation, use a triple backticks on its own line. Optionally, you can add the language next to it in order to activate the syntax highlighting mode.

```ruby
require 'redcarpet'
markdown = Redcarpet.new("Hello World!")
puts markdown.to_html
```
