-The therapy protocol is 16 pages long at the moment. In addition to the therapy, there is also a TROUBLESHOOTING section towards the end of this document, which aims to answer the most common questions about the various therapies for non24 and clarify how they work and how to optimize them according to the current scientific knowledge. This section is much longer than the therapy outline, and hence it is written for the curious reader to further their knowledge and/or answer their questions about or around circadian rhythm disorders. Reading the Troubleshooting section is not mandatory, rather the reader is invited to search there in case of a specific question that is not answered in the therapy outline.

+<h2>How to read and navigate this document</h2>

+<p>
+There is a button "Table of contents" at the top left corner that will show you a navigation bar with where you are in the document and allowing you to quickly jump to any section.

+Each section in the document can be linked to, but there is a bug that makes the first link copy not show the correct anchor, so try to just copy the link twice and the second one should include the correct HTML anchor.

+For people with sighted non-24 or DSPD who just discovered they have this disorder, I recommend first starting in the <a href="" title="Diagnosis and sleep diary section" class="page">Diagnosis and sleep diary section</a> in Troubleshooting, where you will find all the informations you need to start documenting your sleep disorder and find a sleep medicine doctor experienced with circadian rhythm disorders who can help you with getting a formal diagnosis and accommodations that are necessary for school and work, given these are extremely debilitating disorders.

+<p>
+Afterwards or if you have a circadian rhythm disorder but you already are diagnosed or experienced with the clinical process and are looking for a therapy protocol to entrain the circadian rhythm period or phase advance the phase, you can proceed to read the therapy's protocol. I recommend to first read the <a href="" title="Quick protocol" class="page">Quick protocol</a>, to get a nice fast introduction with the big ideas clearly laid out, then if you like what you are reading and want more details, you can proceed to read the <a href="" title="Simplified protocol" class="page">Simplified protocol</a> or even the <a href="" title="Full protocol" class="page">Full protocol</a>.

+<p>
+For people who do not have a circadian rhythm disorder but are suspecting they know someone with such a disorder, for caregiver and for clinicians, you may be mo interesting in reading the <a href="" title="Introduction to the non24 disorder" class="page">Introduction to the non24 disorder</a> (which also covers other circadian rhythm disorders, notably the effects on health). Then you can continue reading on with the section on <a href="" title="Zeitgebers" class="page">Zeitgebers</a> to learn more about circadian rhythm science. For clinicians or the curious minded ones, the next sections afterwards review the scientific and medical literature on sleep to explain the various choices that led to the design of this therapeutic protocol, and some insights into what may help design future circadian rhythm therapies.
