+== Reading material ==
 From the Danish "Teknologisk Institut" I have {{ :bms:bestpractice:water:rorcenter-anvisning_017._legionella.pdf |this description}} (In Danish, anything similar in English would be much appreciated)
 And also a {{ :bms:bestpractice:water:2018_12_03_legionella_pjece.pdf |smaller brochure}}.
+== Tables ==
 What we can use from theese is a table that very clearly describes when the legionella bacteria dies.
