 See the godoc here: https://godoc.org/go.bug.st/serial
 
-## Development
+## go.mod transition
 
-If you want to contribute to the development of this library, you must clone this git repository directly into your `src` folder under `src/go.bug.st/serial` and checkout the branch `v1`.
+This library now support `go.mod` with the import `go.bug.st/serial`.
 
-```
-cd $GOPATH
-mkdir -p src/go.bug.st/
-git clone https://github.com/bugst/go-serial.git -b v1 src/go.bug.st/serial
-go test go.bug.st/serial
-```
-
-## What's new in v1
-
-There are some API improvements, in particular object naming is now more idiomatic, class names are less redundant (for example `serial.SerialPort` is now called `serial.Port`), some internal class fields, constants or enumerations are now private and some methods have been moved into the proper interface.
-
-If you come from the version v0 and want to see the full list of API changes, please check this pull request:

-https://github.com/bugst/go-serial/pull/5/files
+If you came from the pre-`go.mod` era please update your import paths from `go.bug.st/serial.v1` to `go.bug.st/serial` to receive new updates. Anyway, the latest "`v1`" release should still be avaiable using the old import.
