 ## Building the operator
 
-You need Glide to fetch all dependencies. Install it with:
+We use [Go Modules](https://github.com/golang/go/wiki/Modules) for handling
+dependencies. When using Go below v1.13 you need to explicitly enable Go modules
+by setting the `GO111MODULE` environment variable to `on`. The make targets do
+this for you, so simply run
 
 ```bash
-make tools
-```

-Next, install dependencies with glide by issuing:
-
-```bash
-make deps
+make tools deps
 ```
 
 This would take a while to complete. You have to redo `make deps` every time
-you dependencies list changes, i.e. after adding a new library dependency.
