 ## Composition of This Repository and Where/How to Contribute
 
-The repository of the Kubernetes Python client consists of this main repository and a submodule, the [python-base](https://github.com/kubernetes-client/python-base) repository. The main repository contains mostly files that are generated by the OpenAPI generator from [this OpenAPI spec](scripts/swagger.json). The base repo is the utility part of the python client and allows developers to create their own kubernetes clients.

 ### Writing Tests
 
-In addition to running the your fix yourself and tell us that your fix works, you can demonstrate that your fix really works by using unit tests and end to end tests. These unit tests are mainly located in three places. You should put your tests into the places that they fit in.

 1. [Generated tests](kubernetes/test) by OpenAPI generator: these tests should pass and do not require modification.
 2. [End to end tests](kubernetes/e2e_test): these are tests that can only be verified with a live kubernetes server.

 If you write a new end to end (e2e) test, or change behaviors that affect e2e tests, you should set up a local cluster and test them on your machine. The following steps will help you run the unit tests.
 
-1. Acquire a local cluster. [Minikube](https://github.com/kubernetes/minikube) is a good choice for Windows and Linux developers. Alternatively if you are on Linux, you can clone the [kubernetes](https://github.com/kubernetes/kubernetes) and run [install-etcd.sh](https://github.com/kubernetes/kubernetes/blob/master/hack/install-etcd.sh) and then [local-up-cluster.sh](https://github.com/kubernetes/kubernetes/blob/master/hack/local-up-cluster.sh) to get a local cluster up and running.

 2. Run the unit tests. In the root directory of the main repo, run ```python -m unittest discover```.
 
 3. Check the test results and make corresponding fixes.
