+## Your house style
+
+Drawing conventions you want every assistant to follow -- grid, flow
+direction, wire routing, tags, grouping -- written once, in your own words,
+and kept by QElectroTech itself rather than by any one assistant:
+
+```js
+qet.setHouseStyle("Never place a symbol off the 10 px grid.\n...");
+```
+
+It is stored in QElectroTech's settings (needs `QET_ENABLE_SCRIPTING=1`, as
+for any change), written to `qet-assistant.json` as `house_style`, and shown
+by `qet_about`, whose description tells the assistant to follow it. Every
+assistant that connects, of any make, reads the same text.
