Simple Shopify Blog Setup & Category Organization

Hi, I need a quick Shopify blog setup for my store. I already have a Shopify website with a “Blog” link in the main navigation. I want someone to properly connect and organize the blog section so customers can click “Blog” and see all articles in an organized way. This is a simple task. I do not need a full redesign or custom app. What I need: Make sure the “Blog” menu link goes to the correct blog page. Set up the blog page using my existing Shopify theme. Organize posts by simple categories/topics using tags, such as: Maca Psyllium Cacao Matcha Recipes Wellness Make sure blog posts can show a featured/hero image. Make sure the page looks good on mobile and desktop using the existing theme. Show me briefly how to add a new article and assign it to a category/tag. Important: Please do not use paid apps unless I approve first. Please do not redesign the full website. This should be a simple Shopify-native setup using the current theme. Budget: Fixed price: $35 Timeline: I would like this completed within 24–48 hours. Questions: Can you do this using the existing Shopify theme? Can you do it without paid apps? Have you organized Shopify blogs with tags/categories before?
