 ### Presets
 
-iD can use external presets exclusively or along with the default OpenStreetMap presets. This is configured using the `context.presets` accessor. To use external presets alone, initialize the iD context with a custom `Presets` object:
+iD's preset database is stored in the `iD.data.presets` object and can be overridden
+or modified prior to creating the iD context.
 
+The format of the `presets` object is
+[documented here](https://github.com/openstreetmap/iD/tree/master/data/presets#custom-presets).
+
+To add a new preset to iD's existing preset database.
 ```js
-
-var id = iD.Context()
-  .presets(customPresets);
-
+iD.data.presets.presets["aerialway/zipline"] = {
+    geometry: ["line"],
+    fields: ["incline"],
+    tags: { "aerialway": "zip_line" },
+    name: "Zipline"
+};
 ```
 
-The format of the Preset object is [documented here](https://github.com/openstreetmap/iD/tree/master/data/presets#custom-presets).
+To completely replace iD's default presets with your own:
+```js
+iD.data.presets = myPresets;
+```
+
+To run iD with the minimal set of presets that only match basic geometry types:
+```js
+iD.data.presets = {
+    presets: {
+        "area": {
+            "name": "Area",
