 # Cross-compiling
 
-Selecting the target platform is done with the `--platforms` option with `bazel`.
-This command builds release tarballs for Windows:
-
-```
-bazel build --platforms=@io_bazel_rules_go//go/toolchain:windows_amd64 //release:release-tars
+This project uses standard go tools for cross-building.
+```sh
+GOOS=linux GOARCH=amd64 go build ./cmd/cloud-controller-manager
 ```
+Alternatively, run `make bin` to build both server and node binaries for all supported platforms.
 
-This command explicitly targets Linux as the target platform:
-
-```
-bazel build --platforms=@io_bazel_rules_go//go/toolchain:linux_amd64 //release:release-tars
-```
+Server
+  - linux/amd64
 
+Node:
+  - linux/amd64
+  - windows/amd64
 
 # Dependency management
 
-Dependencies are managed using [Go modules](https://github.com/golang/go/wiki/Modules) (`go mod` subcommands).
-
-Note that builds are done with Bazel and not the Go tool. Don't follow public
-Go module docs, instead use instructions in this readme.
-
-## Working within GOPATH
-
-If you work within `GOPATH`, `go mod` will error out unless you do one of:
-
-- move repo outside of GOPATH (it should "just work")
-- set env var `GO111MODULE=on`
+This project manages dependencies using standard [Go modules](https://github.com/golang/go/wiki/Modules) (`go mod` subcommands).
 
 ## Add a new dependency
 
 ```
-go get github.com/new/dependency && ./tools/update_vendor.sh
+go get github.com/new/dependency
 ```
 
 ## Update an existing dependency
 
 ```
-go get -u github.com/existing/dependency && ./tools/update_vendor.sh
+go get -u github.com/existing/dependency
 ```
 
 ## Update all dependencies
 
 ```
-go get -u && ./tools/update_vendor.sh
+go get -u
 ```
 
 Note that this most likely won't work due to cross-dependency issues or repos
