File	Description
Dockerfile	Multi-stage Docker build configuration for building and serving the Docusaurus site
README.md	Added Docker deployment section with local build/run instructions and Docker Hub reference
.github/workflows/deploy.yml	Added dockerhub-release job for automated image building and publishing
docusaurus.config.ts	Disabled blog indexing in theme configuration

[Copilot]

The configuration property 'indexBlog' does not appear to be a valid Docusaurus theme configuration option. Verify that this is the correct property name for disabling blog output. The standard Docusaurus blog plugin configuration typically uses properties like 'blogSidebarCount' or plugin-specific options rather than 'indexBlog' in themeConfig.

Suggested change

indexBlog: false,

[Copilot]

Corrected spelling of 'theartcher' to 'thearcher' in the Docker Hub username.
