+## Building Cortex
+
+To build:
+```
+make
+```
+
+(By default, the build runs in a Docker container, using an image built
+with all the tools required. The source code is mounted from where you
+run `make` into the build container as a Docker volume.)
+
+To run the test suite:
+```
+make test
+```
+
+## Playing in `minikube`
+
+First, start `minikube`.
+
+You may need to load the Docker images into your minikube environment. There is
+a convenient rule in the Makefile to do this:
+
+```
+make prime-minikube
+```
+
+Then run Cortex in minikube:
+```
+kubectl apply -f ./k8s
+```
+
+(these manifests use `latest` tags, i.e. this will work if you have
+just built the images and they are available on the node(s) in your
+Kubernetes cluster)
+
+Cortex will sit behind an nginx instance exposed on port 30080.  A job is deployed to scrape itself.  Try it:
+
+http://192.168.99.100:30080/api/prom/api/v1/query?query=up
+
+If that doesn't work, your Minikube might be using a different ip address. Check with `minikube status`.
+
+### Dependency management
+
+We uses [Go modules](https://golang.org/cmd/go/#hdr-Modules__module_versions__and_more) to manage dependencies on external packages.
+This requires a working Go environment with version 1.11 or greater, git and [bzr](http://wiki.bazaar.canonical.com/Download) installed.
+
+To add or update a new dependency, use the `go get` command:
+
+```bash
+# Pick the latest tagged release.
+go get example.com/some/module/pkg
+
+# Pick a specific version.
+go get example.com/some/module/pkg@vX.Y.Z
+```
+
+Tidy up the `go.mod` and `go.sum` files:
+
+```bash
+go mod tidy
+go mod vendor
+git add go.mod go.sum vendor
+git commit
+```
+
+You have to commit the changes to `go.mod` and `go.sum` before submitting the pull request.
