```powershell
```
$powershellVersion = '6 and lower'
$description = 'custom code fencing example WITH markdown description'
$names | Foreach-Object {} {
write-host 'indentation is respected'
Write-Host 'enormously long lines should not get cut off by our PlatyPS friends, ftw'
}
$emptyNewlinesInCode = $True
\`\`\`
The description would continue after first closing code fence.
This solution:
- respects indentation
- will treat description as markdown
- seems close to what comes natural
With this solution, the description itself could even contain code blocks:
\`\`\`js
$var = docusaurus.New($config);
\`\`\`
Pretty cool and the console becomes more readable too IMO, at least
you now see where the code ends and the explanation begins
\`\`\`
$unMonicked = "should stay unmonicked, in other words powershell should not be added"
$indentationRespected = $True
$theBadNews - "that PlatyPS seems to cut off this line if a .
is detected, wtf"
