+## Dependencies
+
+Project dependencies are commited to the `vendor` directory, so Go 1.6+ users can clone to their `GOPATH` and build or test immediately. Go 1.5 users should set `GO15VENDOREXPERIMENT=1`.
+
+Project developers should use [glide](https://github.com/Masterminds/glide) to manage commited dependencies under `vendor`. Configure `glide.yaml` as desired. Use `glide update` to download and update dependencies listed in `glide.yaml` into `/vendor` (do **not** use glide `get`).
+
+    glide update --update-vendored --strip-vendor --strip-vcs
+
+Recursive dependencies are also vendored. A `glide.lock` will be created to represent the exact versions of each dependency.
+
+With an empty `vendor` directory, you can install the `glide.lock` dependencies.
+
+    rm -rf vendor/
+    glide install --strip-vendor --strip-vcs
