Motivation

Most of the documentation explaining how a user should run the plugin is in a single DoCC file under the ContainerImageBuilderPlugin target (this otherwise empty target is needed because DoCC does not generate documentation for plugins).

This documentation would be easier to read, and easier to expand with more information, if it was split into several sections. This would provide an outline view in the left-hand pane (the "curation") which would allow users to jump directly to sections of interest, and make internal links between documentation sections easier.

Modifications

• Rename ContainerImageBuilderPlugin to swift-container-plugin. swift-container-plugin will hold all the high level documentation, examples and tutorials for the project. A future PR will add a manual page which specifically covers only the plugin.

Result

The existing documentation is better structured. A number of small edits have been made for clarity.

Test Plan

• No functional change.
• DoCC checks are already run by the soundness GitHub CI job and continue to pass; all notes and usage warnings fixed.
