 ```
-go get robpike.io/ivy
+go install golang.org/x/mobile/cmd/gomobile@latest 
+go install golang.org/x/mobile/cmd/gobind@latest
+```
+
+to install `gomobile` and `gobind`. Then:
+
+```
+mkdir work; cd work
+go mod init work
+go get -d golang.org/x/mobile/bind@latest
+go get -d robpike.io/ivy/mobile
 gomobile bind -target=ios robpike.io/ivy/mobile
 ```
 
 Place the mobile.framework directory in this directory, and
 then open ivy.xcodeproj in Xcode.
