+Start reading our code and you'll get the hang of it.
+We optimize for readability:
 
-  * We indent using tab, see https://qelectrotech.org/wiki_new/doc/qt_creator#on_ajoute_le_style_de_code_qet
+  * We use tabs to indent, and interpret tabs as taking up to 8 spaces.
+    see https://qelectrotech.org/wiki_new/doc/qt_creator#on_ajoute_le_style_de_code_qet
+  * We try to keep to at most 80 characters per line.
+  * Try to make your code understandable.
+    You may put comments in, but comments invariably tend to stale out when
+    the code they were describing changes.
+    Often splitting a function into two
+    makes the intention of the code much clearer.
