File	Description
README.md	Updated documentation section to remove references to local docs and guides, now pointing only to GitBook
docs/*.md	Removed 25 documentation files covering workflows, triggers, options, variables, targets, parameters, modules, and guides

Note: While line 54 of README.md (outside the changed region) still references ./docs/getting-started.md which is being removed, this creates a broken link that should be addressed. However, since this line is not within the changed regions of this PR, I cannot create a comment for it. The maintainers should be aware that the "Getting Started" section header and its reference to the local documentation file will become a broken link after this PR is merged.
