+* `infoType` String - Values can be either `basic` for basic info or `complete` for complete info.
+
+Returns `Promise`
+
+For `infoType` equal to `complete`:
+ Promise is fulfilled with `Object` containing all the GPU Information as in [chromium's GPUInfo object](https://chromium.googlesource.com/chromium/src.git/+/66.0.3359.181/gpu/config/gpu_info.cc). This includes the version and driver information that's shown on `chrome://gpu` page.
+
+For `infoType` equal to `basic`:
+  Promise is fulfilled with `Object` containing fewer attributes than when requested with `complete`. Here's an example of basic response:
+```js
+{ auxAttributes:
+   { amdSwitchable: true,
+     canSupportThreadedTextureMailbox: false,
+     directComposition: false,
+     directRendering: true,
+     glResetNotificationStrategy: 0,
+     inProcessGpu: true,
+     initializationTime: 0,
+     jpegDecodeAcceleratorSupported: false,
+     optimus: false,
+     passthroughCmdDecoder: false,
+     sandboxed: false,
+     softwareRendering: false,
+     supportsOverlays: false,
+     videoDecodeAcceleratorFlags: 0 },
+gpuDevice:
+   [ { active: true, deviceId: 26657, vendorId: 4098 },
+     { active: false, deviceId: 3366, vendorId: 32902 } ],
+machineModelName: 'MacBookPro',
+machineModelVersion: '11.5' }
+```
+Using `basic` should be preferred if only basic information like `vendorId` or `driverId` is needed.
