Go to chrome web store and add Tampermonkey to chrome. Now that you have Tampermonkey added to chrome, you will be able to install scripts on tampermonkey. Next to to greasyfork, and install the script Nitro Type auto typer helper v.2. This script will be able to send the information needed for the auto typer to work from the nitro type race. Next we are gonna download the actual auto typer, the auto typer that will type for us. Keep in mind that the previous things we installed are necessary for the auto typer to work. Warning: If you made it this far and if you are going to use the auto typer, make sure you aren't signed in with your main account (the account that you don't want to be banned), since you could possibly get banned if you use the auto typer incorrectly. It might be tricky the first time you do it, but once you know how to do it, it won't be difficult anymore. Open chrome, and the auto typer you downloaded.
Resize chrome and the auto typer so they are side by side as shown in the picture below. When resizing the auto typer, make sure you are able to see the play button at the top right (we will be usin gthat button to make the auto typer type). On the auto typer, next to where it says 'setMySpeed to', type your speed there.
