-## Adding New Content
-
-### Creating a New Blog Post
-
-1. Create a new folder in `content/post/`:
-   ```
-   content/post/my-new-post/
-   └── index.md
-   ```
-
-2. Add front matter and content to `index.md`:
-   ```markdown
-   ---
-   title: "My New Post Title"
-   date: 2025-11-03T10:00:00-06:00
-   description: "Brief description of the post"
-   categories: ["Mathematics", "Technology"]
-   tags: ["functions", "algorithms", "patterns"]
-   image: "cover.jpg"  # Optional: add cover.jpg to the same folder
-   math: true          # Optional: enable math rendering
-   ---
-
-   # Your Post Content
-
-   Write your post content here in markdown...
-   ```
-
-3. Commit and push - your post will be live in minutes!
