* Be sensible
* Be tolerant
+== Dependencies and targets ==
+
+* We target Flash Player 9 at present. Please don't add FP10-specific code yet.
+* Potlatch 2 requires Flex; the Halcyon rendering component doesn't. Don't add Flex stuff (import mx.*) to anything in net.systemeD.halcyon.
+* Both Potlatch 2 and Halcyon can be deployed locally (i.e. not on openstreetmap.org), and indeed can talk to databases other than the main OSM instance. So don't be too OSM-specific
+
== Whitespace ==
* Use space, not tabs. You can only get away with tabs if your name is Richard Fairhurst
== MXML ==
-* Indentation is like the wild west in there. Consistency is king.
\ No newline at end of file

+
+== Icons ==
+
+* POI icons for map_features are 24x24 and come from the CC0-licensed SJJB set (http://www.sjjb.co.uk/icons)
+* POI icons for Halcyon stylesheets are 16x16 and also come from the SJJB set
+* Way icons for map_features are 75x45 and have up to now generally been drawn by Richard (see way_icons.ai)
+* All features must have a unique icon, and all icons must be in the correct style. Do not add a feature without a matching icon.
+* Only deployable files go in resources/ . Vector source files go in resources_src/
