# Markdown Example Document

|
|
## Headings
|
|
Headings are created by adding one or more `#` symbols before your heading text. The number of `#` you use will determine the size of the heading.
|
|
|
|
```
|
|
function a(b: T) {
|
|
|
|
}
|
|
```
|
|
|
|
Remember, markdown processors may have slight differences and extensions, so always refer to the specific documentation or guides relevant to your platform or editor for the best practices and additional features.
