 # Tutorial for Eiffel Bundle
-To be defined
+
+In the following tutorial, you will go through:
+
+1. Deploy Eiffel bundle using Docker.
+1. Check the existing subscriptions.
+1. Publish an Eiffel event which triggers a few Jenkins jobs.
+
+## Prerequisites
+
+1. You have installed and you have set up **Docker**.
+1. You have cloned [eiffel-easy2use](https://github.com/eiffel-community/eiffel-easy2use.git) repository locally.
+
+**_NOTE:_** Eiffel bundle requires **12GB** RAM usage, approximately.
+
+## Start Eiffel Bundle Using Docker
+
+1. Change directory to *eiffel-easy2use*, for example:
+   ```console
+   cd eiffel-easy2use
+   ```
+
+1. Start Eiffel by executing the command:
+   ```console
+   ./easy2use start Eiffel -t Docker -e bundles/ -y
+   ```
+
+1. Wait until all Docker containers are up and running.
+   Check it by executing the command:
+   ```console
+   docker ps
+   ```
+
+## Get the Existing Subscriptions from EI
+
+There are two ways that you can check the existing subscriptions:
+
+1. Execute the following **curl** command:
+   ```console
+   curl -X GET -H "Content-type: application/json" "http://localhost:8077/subscriptions"
+   ```
+
+1. Navigate to **localhost:8077** on your browser and check the subscriptions in the GUI.
+
+## Publish an Eiffel ArtC Event and Trigger the Jenkins Jobs
+
+There are two ways that you can publish an Eiffel event:
+
+1. Execute the following **curl** command:
+   ```console
+   curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' -d '{
+       "meta": {
+            "type": "EiffelArtifactCreatedEvent",
+            "version": "3.0.0",
+            "time": 1234567890,
+            "id": "77a7f4e7-9847-44a6-9bf0-3a19a9528ccd",
+            "source": {
+                "serializer": "pkg:maven/com.mycompany.tools/eiffel-serializer%401.0.3"
+            }
+       },
+       "data": {
+            "identity": "pkg:maven/com.othercompany.library/required@required"
+       }
+    }' "http://localhost:8096/producer/msg?mp=eiffelsemantics"
+   ```
+
+1. Navigate to **localhost:8096** on your browser and publish an 
+   Eiffel event via the *Swagger* interface.
+
+Then,
+
+1. Navigate to *Jenkins* or *Jenkins FEM* GUI, **localhost:8051** or **localhost:8052** correspondingly
+   and check that some jobs have **SUCESS** status.
+
+1. Navigate to **localhost:8084** on your browswer and press the link *"List all events in ER (result will be paginated)"*
+   to view all the Eiffel events that have been created.
+
+## Next Steps
+
+After you have finished the tutorial successfuly, you can experiment with the Eiffel.
+
+For example, you can add a new subscription and publish the corresponding Eiffel event
+that triggers an existing Jenkins job or a new Jenkins job.
+
+## Troubleshooting
+
+1. Limited RAM space can restart frequently a Docker container due to memory allocation error.
+   In this case, check the RAM usage by executing the command:
+
+   ```console
+   free -h
+   ```
+
+1. Check the Docker container logs by executing the command:
+
+   ```console
+   docker logs <container_id>
+   ```
+
+   If there is an error, you can try to restart the container:
+
+   ```console
+   docker restart <container_id>
+   ```
