As we discussed in the community meetings, we should keep Katib README simple with only necessary information.
My Suggestion that we remove the following sections:

1. Getting Started
2. Name
3. Concepts in Katib, since it is similar to: https://www.kubeflow.org/docs/components/katib/overview/#katib-concepts.
   For the Search Algorithms we can create a table with supported AutoML techniques, algorithms. @gaocegege @johnugeorge What do you think ?
4. Components in Katib - We can add this section to kubeflow.org docs.
5. Web UI - similar to https://www.kubeflow.org/docs/components/katib/overview/#hyperparameters-and-hyperparameter-tuning.
6. GRPC API Documentation - Move it to kubeflow.org docs.
7. Katib SDK - Described in https://www.kubeflow.org/docs/components/katib/overview/#katib-interfaces.
8. Quick Start

Installation section should be simplified. Remove it completely and add link to: https://www.kubeflow.org/docs/components/katib/hyperparameter/#installing-katib or explain how to install particular version of Katib.

Contributing and Citation section can be moved to Community.

What do you think @gaocegege @johnugeorge @jbottum @RFMVasconcelos ?
