 ## Workflow
+### Create the Service
 1. Add your additional libraries to the appropriate in file [`env-config`](./env-config/)
-2. The [Dockerfile]({{ cookiecutter.project_slug }}/src/Dockerfile) shall be modified to install additional packages, software and/or Jupyter kernels
-3. The [.osparc](.osparc) is the configuration folder and source of truth for metadata: describes service info and expected inputs/outputs of the service. If you need to change the inputs/outputs of the service, description, thumbnail, etc... check the [`metadata.yml`](./.osparc/metadata.yml) file
-4. Optional: if you need to change the default the start-up behavior of the service, modify the [`boot_notebook.bash`](./boot_scripts/boot_notebook.bash) file
-5. The service docker image may be built with ``make build`` (see "Useful Commands" below)
-6. The service docker image may be run locally with ``make run-local`` (see "Useful Commands" below)
-7. Once you are happy with your code, an automated pipeline will build the Docker image for you (as in step 5)
-8. If you wish to publish you your Service on the o²S²PARC platform, get in touch with [o²S²PARC Support](mailto:support@osparc.io)

-After the initial version, you can update your Service and publish a new version, with ``make version-patch``, or ``make version-minor``, or  ``make version-major``

+3. Optional: the [.osparc](.osparc) is the configuration folder and source of truth for metadata: describes service info and expected inputs/outputs of the service. If you need to change the inputs/outputs of the service, description, thumbnail, etc... check the [`metadata.yml`](./.osparc/metadata.yml) file
+4. Optional: if you need to change the start-up behavior of the service, modify the [`boot_notebook.bash`](./boot_scripts/boot_notebook.bash) file
+5. Optional (for testing): The service docker image may be built with ``make build`` (see "Useful Commands" below)
+6. Optional (for testing): The service docker image may be run locally with ``make run-local`` (see "Useful Commands" below)
+
+### Publish the Service on o²S²PARC
+Once you're happy with your code:
+1. Push it to a public repository.
+2. An automated pipeline will build the Docker image for you (as in step 5), via GitHub actions or a GitLab CI (see `.github` or `.gitlab` folders)
+3. Check that the automated pipeline executes successfully
+4. Once the pipeline has run successfully, get in touch with [o²S²PARC Support](mailto:support@osparc.io), we will take care of the final steps!
+
+### Change the Service (after it has been published on o²S²PARC )
+If you wish to change your Service (e.g. add additional librarie), after it has been published on o²S²PARC, you have to **create a new version**:
+1. Go back to your repository
+2. Apply the desired changes
+3. Increase ("bump") the Service version: in your console execute: ``make version-patch``, or ``make version-minor``, or  ``make version-major``
+4. Commit and push the changes to your repository
+5. Wait for the GitHub/GitLab pipelines to run successfully
+5. Once the pipeline has run successfully, get in touch with [o²S²PARC Support](mailto:support@osparc.io), we will take care of tpublishing the new version!
