-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).
+# [Next.js](https://nextjs.org/) NFT Mint dApp
 
-## Getting Started
+A simple, fast and modern dApp for minting NFTs.
 
-First, run the development server:
+Just set up some configurations and add your own **ABI**.
 
-```bash
+The actual dApp is here: [Skulls In Love](https://www.skullsin.love/)
-npm run dev
+
-# or
+## Usage
-yarn dev
+
+1. Clone this project:
+
+```sh
+git clone https://github.com/kjmczk/nextjs-nft-mint-dapp.git
 ```
 
-Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+2. Change into the directory:
 
-You can start editing the page by modifying `pages/index.tsx`. The page auto-updates as you edit the file.
+```sh
+cd nextjs-nft-mint-dapp
+```
 
-[API routes](https://nextjs.org/docs/api-routes/introduction) can be accessed on [http://localhost:3000/api/hello](http://localhost:3000/api/hello). This endpoint can be edited in `pages/api/hello.ts`.
+3. Install the dependencies:
 
-The `pages/api` directory is mapped to `/api/*`. Files in this directory are treated as [API routes](https://nextjs.org/docs/api-routes/introduction) instead of React pages.
+```sh
+npm install
+```
 
-## Learn More
+4. Set up some configurations:
 
-To learn more about Next.js, take a look at the following resources:
+Set the values of environment variables in the `.env.development`, `.env.production`, and `.env` files to yours.
 
-- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+5. Add your **ABI**:
-- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
 
-You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!
+Copy your contract **ABI** from the [Remix](https://remix.ethereum.org/) and paste it into `contract/abi.json`.
 
-## Deploy on Vercel
+See the [Remix documentation](https://remix-ide.readthedocs.io/en/latest/run.html) for how to generate an ABI.
 
-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.
+6. Run the server:
 
-Check out our [Next.js deployment documentation](https://nextjs.org/docs/deployment) for more details.
+```sh
+npm run dev
+```
