+# Use .config to store your project configs
 
-dot-config.github.io website
+The goal of dot-config is to promote standardization of `.config` folder
+for storing project specific tool configurations.
+
+By using a subfolder you will help **decluttering project root folder**
+and **isolating configuration** from other project files.
+
+Use of `.config` is based on long standing [XDG](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html)
+standard which promoted the use of `~/.config` for keeping **user settings**.
+We only extended the concept to project repositories.
+
+## Projects already supporting .config at repository level
