+# ini-decode
+
+ini file decoder for Node.js, using this util, you can read `.ini` file and even parse it to `.d.ts` file
+
+## installation
+
+```
+npm install ini-decode
+```
+
+## usage
+
+```typescript
+import fs from 'fs'
+import { decode } from 'ini-decode'
+
+//parse
+const { json: configs, dts } = decode(fs.readFileSync('/path/to/ini'))
+
+//this is configs
+console.log(configs)
+
+//you can write dts to a .d.ts file
+fs.writeFileSync('/path/to/ini.d.ts', dts)
+```
