It sounds like its arriving in the crate. You'll need to open the crate, unbolt it from the bottom, and install the front wheel. Its best to have someone help you until the front wheel is on. Remove the brackets that held it in the crate. If its a C5 or B5 make sure the fork tube covers and fender are aligned or you will scratch paint. I think you need to prep the battery by adding the liquid and putting it on a charger. Inflate the tires, connect the speedo cable, check the oil level, and install the battery. Check the chain tension. Adjust the rear brake and make sure the front brake has fluid and grabs.
Then move on to making sure everything is tight and generally checking things over. That's all I remember from the last time I uncreated one. Hope it helps.
