+[Public base path](https://vitejs.dev/guide/build.html#public-base-path) string for Vite, this affects the routing, history and asset links. Make sure to provide appropriately since GitHub Pages stores your app in a directory under a subdomain.

 Under normal circumstances, you don't need to provide/override this parameter, action will set it to your repo name appropriately.
 
+#### Here's how `public_base_path` is resolved:
+
+- If `public_base_path` parameter/input is provided, it will be used regardless.
+- If `public_base_path` parameter/input is **NOT** provided:
+  - If the repository root has `CNAME` file for GitHub Pages Custom Domain setup, then `public_base_path` default value will resolve to `/`
+  - If the repository root does **NOT** have `CNAME`, `public_base_path` default value will resolve to `/{your-repo-name}`

+See the suggestion for the CNAME expansion [here](https://github.com/skywarth/vite-github-pages-deployer/issues/5)
+
+Grateful to the [Greg Sadetsky](https://github.com/gregsadetsky) for his proposition on alternating default value of this input. Also, thankful for his collaboration on explaining GitHub pages custom domain setting and testing phase of these changes.
