+
+## Introduction
+
+We show how to use a database for testing.
+
+## Run postgresql container
+    
+  ```bash
+  docker run --rm --name postgres \
+    -e POSTGRES_USER=postgres \
+    -e POSTGRES_PASSWORD=postgres \
+    -e POSTGRES_DB=tfgrid-graphql \
+    -p 5432:5432 -d postgres
+  ```
+
+## Create the DB
+you can either Generate a db with relevant schema to test things locally quickly, or load a previously taken DB dump file:
+
+### Method 1: Generate a db with relevant schema using the db helper tool:
+
+    ```bash
+    cd tools/db/ && go run . \
+      --postgres-host 127.0.0.1 \
+      --postgres-db tfgrid-graphql \
+      --postgres-password postgres \
+      --postgres-user postgres \
+      --reset \
+    ```
+
+### Method 2: Fill the DB from a Production db dump file, for example if you have `dump.sql` file, you can run: 
+
+    ```bash
+    psql -h 127.0.0.1 -U postgres -d tfgrid-graphql  < dump.sql
+    ```
