+# Haystack Annotation Tool
+
+This document describes setting up the Haystack Annotation Tool with the publicly available Docker Images. Alternatively,
+a hosted version of the tool is available at https://annotate.deepset.ai/login.
+
+
+
+# Setup Annotation Tool with Docker
+
+1. Configure credentials & database in the `docker-compose.yml` file:
+
+The credentials should match in database image and application configuration.
+
+    DEFAULT_ADMIN_EMAIL: "example@example.com"
+    DEFAULT_ADMIN_PASSWORD: "DEMO-PASSWORD"
+
+    PROD_DB_NAME: "databasename"
+    PROD_DB_USERNAME: "somesafeuser"
+    PROD_DB_PASSWORD: "somesafepassword"
+
+
+    POSTGRES_USER: "somesafeuser"
+    POSTGRES_PASSWORD: "somesafepassword"
+    POSTGRES_DB: "databasename"
+
+
+2. Run docker-compose by executing `docker-compose up`.
+
+
+3. The UI should be available at `localhost:7001`.
