 NOTE: ArcAds SRA implementation calls enableSingleRequest() which means that when using pubads lazyLoad functions together with SRA, when the first ad slot comes within the viewport specified by the fetchMarginPercent parameter, the call for that ad and all other ad slots is made. If different behavior is desired after the initial SRA call is made, an outside lazy loading library may be used to manage the calls for regsterAd, reserveAd and other calls.

 | Command  | Description |
 | ------------- | ------------- |
-| `yarn dev`  | Runs the development command, watches for changes and compiles the changes down to the `dist` directory.  |
-| `yarn build`  | Builds the project into the `dist` directory with minification.  |
-| `yarn docs`  | Generates ESDoc documentation in the `docs` directory on-demand.  |
-| `yarn test`  | Runs a series of unit tests with Jest. Tests are automatically validated during a pull request.  |
-| `yarn debug`  | Starts a local http server so you can link directly to the script during development. For example `<script src="http://localhost:9000/dist/arcads.js"></script> |

 ### Slot Override
 You can override the slot name of every advertisement on the page by appending `?adslot=` to the URL. This will override whatever is placed inside of the `slotName` field when invoking the `registerAd` method. For example, if you hit the URL `arcpublishing.com/?adslot=homepage/myad`, the full ad slot path will end up being your DFP id followed by the value: `123/homepage/myad`.
 
 You can also debug slot names and GPT in general by typing `window.googletag.openConsole()` into the browsers developer console.
 
+### Logging
+To inspect the funtion calls taking place within the ArcAds library, you can include the `debug=true` query parameter on your page.
