-This is a [Next.js](https://nextjs.org/) project bootstrapped with [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app).
+# `Nocturne: personal website & CMS`
 
-## Getting Started
+This is the code repo of my personal website, and [here](https://github.com/Lumither/blog-posts/) is the link of the
+content repo.
 
-First, run the development server:
+Powered by Next.js and Rust, built with passion and love
 
-```bash
-npm run dev
-# or
-yarn dev
-# or
-pnpm dev
-# or
-bun dev
-```
+<p align="center">
+  <img src="https://avatars.githubusercontent.com/u/46409277?v=4" alt="GitHub Avatar"/>
+</p>
 
-Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+*will add more here in the future
 
-You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+## Nav:
 
-This project uses [`next/font`](https://nextjs.org/docs/basic-features/font-optimization) to automatically optimize and load Inter, a custom Google Font.
+    <todo>
 
-## Learn More
+## Todos:
 
-To learn more about Next.js, take a look at the following resources:
+### Backend
 
-- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
-- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+- [ ] Add: log system
+- [ ] Add: search api
+- [ ] Add: tag filter (api)
+- [ ] Abandon: UUID mechanism
+- [ ] Fix: db connection issue
 
-You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!
+### Frontend
 
-## Deploy on Vercel
+- [ ] Page: Home
+- [ ] Page: About
+- [ ] Page: Tags
+- [ ] Page: Archive
+- [ ] Page: Search
+- [ ] Add: Right sidebar
 
-The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
