 ### 📚 Adding a new theme
-Would you like to add a new theme to the list? You're lucky, every new theme is welcomed!  
-It's actually pretty easy to add a new theme. 
-
-After following our contributing guidelines, you should have your own fork cloned locally. If so, search for the [themes.ts](https://github.com/0l1v3rr/github-readme-tech-stack/blob/master/src/cards/themes.ts) file. Please follow the code structure you see there.
-
-You only have to specify a `set` method:
-```ts
-// the theme name should be snake_case
-themes.set("theme_name", {
-  backgroundColor: "#ffffff", // the background color of the card
-  borderColor: "#ffffff",     // the border color of the card
-  textColor: "#ffffff",       // the text color inside the badge
-  titleColor: "#ffffff",      // the title color
-  badgeColor: "#ffffff",      // the background color of the badges
-});
-```
-> **Note**  
-> Adding the theme to the README is not necessary.
