I have created a website using Jekyll with the default theme minima. The homepage of this website shows the blog posts.
I would like to show a static page, like about.md, as the homepage and move the blog posts to a link such as website.com/blog/.
Since you're using Minima as your site's theme, what you're looking for can be easily achieved.
Step 1: Add a new folder named blog at the root of your website.
Step 2: Create an index.md page with the home layout, inside this blog directory.
---
# This file is at `./blog/index.md`
layout: home
title: Morteza's Blog
---
Step 3: Change your original ./index.md file to use the page layout.
---
# This file is at `./index.md`
layout: page
title: Landing Page
---
NOTE: If you don't want to maintain a blog directory just to house a single index.md file, you can create a file called blog.md and set it use the home layout and render into blog/index.html
---
# This file is at `./blog.md`
layout: home
title: Morteza's Blog
permalink: /blog/
