+# Staging Directory
+
+This directory contains markdown post files that are being staged for preview before publication.
+
+## Structure:
+- `staging/` - Contains draft/preview post files
+- `_posts/` - Contains published post files
+
+## Workflow:
+1. During preview builds, new post `.md` files are copied here
+2. Jekyll builds the site with both `_posts/` and `staging/` content
+3. After review and approval, posts are moved from `staging/` to `_posts/`
+4. Staging directory is cleaned up after merge
