Worked on the etcd-io/website repository to update documentation related to supported platforms across versions v3.5 to v3.7. Focused on maintaining consistency in platform support information, the work involved adding ARM64 Darwin (Tier 3) support and removing ARM Linux and 386 Linux from the documented matrix to reflect current project scope. Used Markdown to ensure clear and accessible documentation, aligning updates with the product roadmap for multi-architecture support. The approach emphasized accuracy and clarity, helping users understand platform availability. This contribution centered on documentation skills and cross-version maintenance, with all changes tracked in a single feature commit for transparency.
