 A go package to create HTTP ETags (as defined in RFC 7232) for use in HTTP responses.
 
 ## Installation
 You can download the package using
 ```sh
-go get github.com/amalfra/etag
+go get github.com/amalfra/etag/v2
 ```
 
 ## Usage
 Next, import the package
 ``` go
 import (
-  "github.com/amalfra/etag"
+  "github.com/amalfra/etag/v2"
 )
 ```
 You can now call the ```generate``` function to create an ETag. The second parameter is a boolean which specifies whether the generated ETag must be weak or not.
