-The Storage Password is available in Bunny's **Storage Zone → FTP & API Access** section. Never expose it as a `VITE_` variable. In Academy, instructors can upload only JPG, PNG, or WebP cover images; the API verifies the image bytes and uploads them under a generated `covers/` filename. The CDN URL is then saved on the course.
+The Storage Password is available in Bunny's **Storage Zone → FTP & API Access** section. Never expose it as a `VITE_` variable. In Academy, instructors can upload JPG, PNG, or WebP cover images and PDF, DOCX, XLSX, CSV, or ZIP support materials; the API validates the file bytes and determines the material type and size automatically. Covers are stored under `covers/` and course materials under `materials/`.
