-```bash
-npm i -g @pliny/cli
-pliny new --template=starter-blog my-blog

-Alternatively to stick with the current version, TypeScript and Contentlayer:
-
-```bash
-npx degit 'timlrx/tailwind-nextjs-starter-blog#contentlayer'
-```
-
-or JS (official support)
 
 ```bash
 npx degit https://github.com/timlrx/tailwind-nextjs-starter-blog.git
 ```
 
+or with TypeScript (community support)
+
+```bash
+npx degit timlrx/tailwind-nextjs-starter-blog#typescript
+```
