 It is generally recognised that _newly_ diagnosed type 1 diabetics (who often have very high HbA1c at diagnosis, before starting insulin therapy) appear to be able to rapidly reduce their HbA1c immediately after diagnosis without encountering these risks to the same extent, because they have not had elevated blood glucose levels for such a sustained period. However, it is still a consideration which you should discuss with your clinician.

-### Key Principles
+### Key principles of looping with AAPS
 
 The key principles and concepts of looping must be understood before using **AAPS**. This is achieved by investing your personal time into reading the **AAPS** documentation, and completing the Objectives which aim to provide you with a solid platform for safe and effective use of **AAPS**. The volume of **AAPS** documentation may seem overwhelming at first but be patient and trust the process - with the proper approach, you'll get there! 
 
-The speed of progression will depend upon the individual, but be aware that completion of all the objectives typically takes 6 - 9 weeks. A detailed breakdown of the timeline is given below, be aware that by objective 8 of AAPS you are closed looping, the later objectives add in additional features like **SMS commands** and **automations** which are useful to some users, but not essential to the core function of **AAPS**. 
+The speed of progression will depend upon the individual, but be aware that completion of all the objectives typically takes 6 - 9 weeks. Many people start to build, install and setup **AAPS** well in advance of starting to use it. To aid with this, the system has a "virtual pump" which can be used during completion of the early objectives, so that you can become familiar with **AAPS** without actually using it to deliver insulin. A detailed breakdown of the timeline is given below, be aware that by objective 8 of **AAPS** you are closed looping, the later objectives add in additional features like **SMS commands** and **automations** which are useful to some users, but not essential to the core function of **AAPS**. 
 
 Success with **AAPS** requires a proactive approach, a willingness to reflect on the BG data and flexibility to make the necessary adjustments to **AAPS** in order to improve your outcomes. Just as it is nearly impossible to learn to play a sport by reading about the rules alone, the same can be said of **AAPS**.
