I found the following discrepancies on https://developers.redhat.com/products/fuse/hello-world/#fndtn-karaf-runtime:

2. Set up your development environment
The embedded video is obsolete. It describes installation of JBoss Developer Studio 9.1.0.GA the latest version is 11.0.0.GA.

2. Set up your development environment step 3e
The feature is now named JBoss Fuse Tooling instead of JBoss Fuse Development

3. Build your first application
There are three terms for one thing:

• Deploy the Project to the Server - step 5 - Terminal tab
• Test the Project - Use log:display in the Fuse shell to check out the business logging.
• Undeploy the Project - step 5 - ... issuing the command in the Fuse console: osgi:list ...

We should be consistent and use only one term for it --> I suggest to change it to Fuse shell in Terminal view
