Usually, this command is used for including code snippets and examples. In this case, oftens one would include a specific part of the file e.g. which only contains the relevant lines for the example. We support four different modes of partial includes: ```hbs -{{#include file.rs:2}} -{{#include file.rs::10}} -{{#include file.rs:2:}} -{{#include file.rs:2:10}} +\{{#include file.rs:2}} +\{{#include file.rs::10}} +\{{#include file.rs:2:}} +\{{#include file.rs:2:10}} ``` The first command only includes the second line from file `file.rs`.
