+
+Extractor for Machine Learning(ML) Models from [Merlin][merlin].
+
+The extractor uses the REST API exposed by Merlin to extract models. The REST
+API has been documented with Swagger and can be seen [here][merlin-swagger].
+
+## Usage
+
+```yaml
+source:
+  name: merlin
+  scope: staging
+  config:
+    url: my-company.com/api/merlin/
+    service_account_base64: |
+      ____base64_encoded_service_account_credentials____
+```
+
+## Inputs
+
+| Key                      | Value    | Example                                  | Description                                                               | Required? |
+|:-------------------------|:---------|:-----------------------------------------|:--------------------------------------------------------------------------|:----------|
+| `url`                    | `string` | `my-company.com/api/merlin/`             | Merlin's API base URL                                                     | ✅         |
+| `service_account_base64` | `string` | `____BASE64_ENCODED_SERVICE_ACCOUNT____` | Service Account credentials in base64 encoded string.                     | ❌         |
+| `request_timeout`        | `string` | `10s`                                    | Timeout for HTTP requests to Merlin API                                   | ❌         |
+| `worker_count`           | `int`    | `5`                                      | Number of workers to spawn for extracting projects parallely from Merlin. | ❌         |
+
+### Notes
+
+- Leaving `service_account_base64` blank will default
+  to [Google's default authentication][google-default-auth]. It is recommended
+  if Meteor instance runs inside the same Google Cloud environment as the
+  BigQuery project.
+
+## Outputs
+
+The models are mapped to an [`Asset`][proton-asset] with model specific metadata
+stored using [`Model`][proton-model]. Please refer the proto definitions for
+more information.
+
+A single model asset includes all the active model versions. A model version is
+considered active if it has an endpoint.

+### `Resource` upstreams
+
+The extractor currently has limited support for constructing the upstreams for
+Model that utilises the env vars for `standard` transformer. It parses the
+feature table specs that specify the project name and feature table name of the
+[CaraML Store][caraml-store] Feature Table from the env vars. This information
+is used to construct the upstreams for the model.
