+# Install
+
+
+```shell
+npm install -g @karmada/i18n-tool
+```
+
+
+# Basic Usage
+For a whole frontend project which need to i18n, you can do as following:
+```shell
+# init config for under your project
+# here you can modify the config according to the instructions
+i18n-tool/node_modules/.bin/i18n-tool init
+
+# scan the Chinese and replace with i18n function invoke
+# generate corresponding locales files
+i18n-tool/node_modules/.bin/i18n-tool scan -c ./i18n.config.cjs
+```
+
+For a directory which need to i18n, you can specify with `-d` options 
+```shell
+i18n-tool/node_modules/.bin/i18n-tool scan -d directory/to/your/code
+```
+
+For a single file which need to i18n, you can specify with `-f` options 
+```shell
+i18n-tool/node_modules/.bin/i18n-tool scan -f path/to/your/code/file
+```
+
+# Advanced Usage
+For those advanced developer, maybe they need to specify glossaries install of automatic translation. For these kind of 
+scenarios, you can create a `glossaries.csv` under the directory of locales, the format of `glossaries.csv` should like
+```csv
+i18n-key,zh-CN,en-US
+86385379cf9cfbc2c554944f1c054a45,概览,Overview
+21a4e07b08a4efbbfe2b9d88c208836a,多云资源管理,MultiCloud Resource Management
+85fe5099f6807dada65d274810933389,集群,Cluster
+```
+after create the `glossaries.csv`, for the same i18n-key, `i18n-tool` will use the content specified in `glossaries.csv` 
+instead of automatic translation.
