If you have a JavaScript project where TypeScript needs additional guidance to understand global dependencies, or have disabled the built-in inference via disableFilenameBasedTypeAcquisition.

You can use include to specify which types should be used from DefinitelyTyped:

{
  "typeAcquisition": {
    "include": ["jquery"]
  }
}

{
  "typeAcquisition": {
    "include": ["jquery"]
  }
}
