+
+You can use the `arrayOfDoublesSketch` aggregator to:
+
+- Build a sketch from raw data. In this case, set `metricColumns` to an array.
+- Build a sketch from an existing `ArrayOfDoubles` sketch . In this case, leave `metricColumns` unset and set the `fieldName` to an `ArrayOfDoubles` sketch with `numberOfValues` doubles. At ingestion time, you must base64 encode `ArrayOfDoubles`  sketches at ingestion time.
+
+#### Example on top of raw data
+
+Compute a theta of unique users. For each user store the `added` and `deleted` scores. The new sketch column will be called `users_theta`.
+
+```json
+{
+  "type": "arrayOfDoublesSketch",
+  "name": "users_theta",
+  "fieldName": "user",
+  "nominalEntries": 16384,
+  "metricColumns": ["added", "deleted"],
+}
+```
+
+#### Example ingesting a precomputed sketch column
+
+Ingest a sketch column called `user_sketches` that has a base64 encoded value of two doubles in its array and store it in a column called `users_theta`.
+
+```json
+{
+  "type": "arrayOfDoublesSketch",
+  "name": "users_theta",
+  "fieldName": "user_sketches",
+  "nominalEntries": 16384,
+  "numberOfValues": 2,
+}
+```
