-## Deploy Hasura GraphQL Engine on Koyeb
+## One-click deploy to Koyeb
 
-To deploy the Hasura GraphQL Engine on Koyeb, we use the `hasura/graphql-engine` Docker image.
+To deploy Hasura to Koyeb quickly, click the button below:
 
-On the Koyeb control panel, click the **Create App** button. You land on the Koyeb App creation form.

+Click the **Deploy** button when you are finished.  When the deployment completes, you can [access the Hasura Console](#access-the-hasura-console).

+3. Click the **Advanced** button to access additional options.
+
+4. In the **Environment variables** section, configure the environment variables required to properly run the Hasura GraphQL Engine:
+
+   - `HASURA_GRAPHQL_DATABASE_URL`: The environment variable containing the PostgreSQL URL, i.e.  `postgres://<user>:<password>@<host>:<port>/<database>`. Since this value contains sensitive information, select the "Secret" type.  Secrets are encrypted at rest and are ideal for storing sensitive data like API keys, OAuth tokens, etc.  Choose "Create secret" in the "Value" drop-down menu and enter the secret value in the "Create secret" form.
+   - `HASURA_GRAPHQL_ENABLE_CONSOLE`: Set to `true`. This will expose and allow you to access the Hasura Console.
+   - `HASURA_GRAPHQL_ADMIN_SECRET`: The secret to access the Hasura Console. As with the `HASURA_GRAPHQL_DATABASE_URL`, we strongly recommend using a secret to store this value.
+
+5. In the **Exposing your service** section, change the `Port` from `80` to `8080` to match the port that the `hasura/graphql-engine` Docker image app listens on. Koyeb uses this setting to perform application health checks and to properly route incoming HTTP requests. If you want the Hasura GraphQL Engine to be available on a specific path, you can change the default one (`/`) to the path of your choice.

+6. Give your App a name, i.e `hasura-demo`, and click **Deploy**.
 
 The deployment should be up and running in a few seconds.
