 ## カメラを使えるようにする
-Usageで書いたが，`npm install`で自動で設定されるが，注意が必要なので[opencv4nodejs](https://www.npmjs.com/package/opencv4nodejs#how-to-install)が使えれるよう事前に準備しておく.
+Usageで書いたが，`npm install`で自動で設定されるが，注意が必要なので[opencv4nodejs](https://www.npmjs.com/package/opencv4nodejs#how-to-install)が使えれるよう事前に準備しておく.
 
 # Usage
 1. `npm install`
 2. `npm start`  
 を実行.
-途中でErrorが出たらまあ頑張れ. 多分`package-lock.json`, `token.json`を消してみるか, opencv4nodejsに必要なcmake, gcc, python等のlibraryを`apt`や`brew`で入れれば治る.
