+### Generate and Mint full onchain bird
+- You can generate random bird images using a script.
+- Using the deployed contract, you can base64 encode the generated bird image and set it as the tokenURI to mint it as a full onchain NFT.
+
+- Create bird
+  - You can start the server to get or generate images.
+  - If the target tokenId exists, it will be retrieved; if not, it will be generated.
+```
+% cd flutter_bird_image_server
+% npm run start
+% curl -o image.png http://localhost:3000/image/:tokenId
+```
+
+- Mint full onchain bird
+  - We recommend minting from Flutter Birds, but you can also mint it manually.
+  - The generated image is used to mint NFTs.
+  - Please run it in the environment where you deployed the contract.
+  - Please change the filePath of toenInfo in `mint_random_skin.js` as appropriate.
+  - Please execute the following in your docker environment.
+
+```
+# node scripts/mint_full_onchain_bird/mint_random_skin.js
