+## A tiny cli to handle ICU errors on locales files.
+## Install
+
+Requirements
+- Node should be installed
+
+```bash
+$ pnpm add -D @scaleway/validate-icu-locales
+```
+## Usage
+
+We can parse JSON, TS and JS if theses files use default export.
+
+
+```
+validate-icu "../**/en.json"
+```
+
+If there is an error on a local, the CLI will throw an Error and print all errors.
+
+
+## Error
+```
