 Classic way to get go-echarts
 
 ```shell
-$ go get -u github.com/go-echarts/go-echarts/...
-
 # this may be a stupid way to use v2 go-echarts without gomod(GO111MODULE=off) because of
-# the gomod version management system... 🐶
+# the next generation version management system... 🐶
 # if you get a better workaround, please let me know....
+
+$ go get -u github.com/go-echarts/go-echarts/...
 $ cd $go-echarts-project
 $ mkdir v2 && mv charts components datasets opts render templates types v2
 ```
 
 Use gomod style
 
 ```shell
+$ go get -u github.com/go-echarts/go-echarts/v2/...
+```
+
+OR
+
+```shell
+# go.mod

 require github.com/go-echarts/go-echarts/v2
 ```
 
 ### ⏳ Version
 
 The go-echarts project is being developed under v2 version and the active codebase is on the master branch now.
 
-v1 and v2 are incompatible which means that you cannot upgrade go-echarts from v1 to v2 smoothly. But I think it is worth trying the new version.
