  A new approach has been recently developed to study the arithmetic of
hyperelliptic curves $y^2=f(x)$ over local fields of odd residue characteristic
via combinatorial data associated to the roots of $f$. Since its introduction,
numerous papers have used this machinery of "cluster pictures" to compute a
plethora of arithmetic invariants associated to these curves. The purpose of
this user's guide is to summarise and centralise all of these results in a
self-contained fashion, complemented by an abundance of examples.
