The web console has a Wiki which acts as a place you can store any documentation or App Zips.
You can add or remove an App Zip by dragging folders from the wiki's view to your file system; or dragging an App Zip from your file system and dropping it onto the file listing view in the Wiki.
You can use the mvn fabric8:deploy goal to run the zip goal to make an App Zip and then post it to the App Library in your web console using the FABRIC8_CONSOLE environment variable.
e.g. run the following
git clone https://github.com/fabric8io/quickstarts.git
cd quickstarts
mvn install
cd quickstarts/java/camel-spring
mvn clean install fabric8:deploy
