+## Dependency Vendoring
+
+acbuild vendors its dependencies. This is done mostly with the [glide][1] tool,
+and [glide-vc][2] is used to strip unnecessary files from the dependencies.
+
+These tools can be easily installed with a couple of `go get` commands.
+
+```
+go get github.com/Masterminds/glide
+go get github.com/sgotti/glide-vc
+```
+
+This will fetch both tools, build them, and put the binaries in `$GOPATH/bin`.
+
+### Adding a Dependency
+
+```
+glide get -s -u -v <package-name>
+glide vc --only-code --no-tests
+```
+
+### Updating a Dependency
+
+Edit the `glide.yaml` file in the repository, and then run:
+
+```
+glide up -s -u -v
+glide vc --only-code --no-tests
+```
+
+### Removing a Dependency
+
+```
+glide rm --delete <package-name>
+```
