Is there a component name for "knowledge article" to search the full HTML and or content in knowledge articles?

How do you use this to retrieve all metadata using VS code with SFDX extensions installed?

How do you use this to retrieve all metadata using VS code with SFDX extensions installed?

Figured it out:

1. Create a manifest folder in your project folder
2. Put the package.xml file in there
3. Run the command SFDX: Retrieve Source in Manifest from Org
4. Once finished, all the source folders appear in the explorer tab

awesome! thanks for sharing!
