So You Created a Wormhole: The Time Traveler's Guide to Time Travel by Phil Hornshaw & Nick Hurwitch

This guide is for a situation that doesn't actually exist, but is supposed to occur in the near future. The possibility of time travel has come true, and many people are doing it for many reasons. This guide offers some advice for those who plan to engage in this activity.
The book begins with warnings against reading the book. The authors purport to be representatives of the Qualified Users and Negotiators of Time Travel Universal Ministry (QUAN+UM). They discourage the increase in the number of people engaged in time travel, especially by those unprepared, and they are worried about ill-prepared time travellers making serious mistakes that will affect the present and future, not to mention the past.
Once they've assumed that you are reading it anyway, it continues with a welcome and introduction to the details of time travel. They go on to show that the ideas that you may have about time travel may not be realistic.
The third chapter is on time machines, how to build them and destroy them. The fourth chapter talks about potential paradoxes and what they could mean for you. The fifth chapter deals with the complexities of existing in different times, engaging with other time travellers, or even yourself.
They go on to discuss the necessity of fixing a timeline if you have screwed it up, something that is expected to be done. Included here is a timeline of time travel events.
The next section of the book deals with survival in different times. It begins with an overall introduction and then is split into sections of time: Prehistory; Dawn of Man; Empires; Middle Ages; Industry; Computers; Robots; Space Travel; and the End of Time.
Each of this has sections that help you identify the time from your surroundings, things to bring, things that happen during this time; creatures and people you might encounter and how to best deal with them, how to repair your time machine should that be necessary, and how to blend in.
The book ends with some information about the Ministry.
I found it an amusing read, with references to various books, movies, and TV shows that have had elements of time travel in them.
