Query regarding shortcode blocks

[SoulPancake]

What is the source for shortcodes like this within the markdown files

redis-doc/commands/set.md

Line 43 in 284dc0a

{{< clients-example set_and_get />}}

Asking because I'm interested in contributing to Code examples in the documentations like the following and citing the source for go-redis or rueidis ( in Golang )
