-# Developer Guide
-
-This developer guide is for people who want to contribute to the Katib project.
-If you're interesting in using Katib in your machine learning project,
-see the following guides:
-
- [Getting started with Katib](https://kubeflow.org/docs/components/katib/hyperparameter/).
- [How to configure Katib Experiment](https://kubeflow.org/docs/components/katib/experiment/).
- [Katib architecture and concepts](https://www.kubeflow.org/docs/components/katib/reference/architecture/)
-  for hyperparameter tuning and neural architecture search.
-
-## Requirements
-
- [Go](https://golang.org/) (1.22 or later)
- [Docker](https://docs.docker.com/) (24.0 or later)
- [Docker Buildx](https://docs.docker.com/build/buildx/) (0.8.0 or later)
- [Java](https://docs.oracle.com/javase/8/docs/technotes/guides/install/install_overview.html) (8 or later)
- [Python](https://www.python.org/) (3.11 or later)
- [kustomize](https://kustomize.io/) (4.0.5 or later)
- [pre-commit](https://pre-commit.com/)
-
-## Build from source code
-
-**Note** that your Docker Desktop should
-[enable containerd image store](https://docs.docker.com/desktop/containerd/#enable-the-containerd-image-store)
-to build multi-arch images. Check source code as follows:
-
-```bash
-make build REGISTRY=<image-registry> TAG=<image-tag>
-```
-
-If you are using an Apple Silicon machine and encounter the "rosetta error: bss_size overflow," go to Docker Desktop -> General and uncheck "Use Rosetta for x86_64/amd64 emulation on Apple Silicon."
-
-To use your custom images for the Katib components, modify
-[Kustomization file](https://github.com/kubeflow/katib/blob/master/manifests/v1beta1/installs/katib-standalone/kustomization.yaml)
-and [Katib Config](https://github.com/kubeflow/katib/blob/master/manifests/v1beta1/installs/katib-standalone/katib-config.yaml)
-
-You can deploy Katib v1beta1 manifests into a Kubernetes cluster as follows:
-
-```bash
-make deploy
-```
-
-You can undeploy Katib v1beta1 manifests from a Kubernetes cluster as follows:
-
-```bash
-make undeploy
-```
-
-## Technical and style guide
-
-The following guidelines apply primarily to Katib,
-but other projects like [Training Operator](https://github.com/kubeflow/training-operator) might also adhere to them.
-
-## Go Development
-
-When coding:
-
- Follow [effective go](https://go.dev/doc/effective_go) guidelines.
- Run locally [`make check`](https://github.com/kubeflow/katib/blob/46173463027e4fd2e604e25d7075b2b31a702049/Makefile#L31)
-  to verify if changes follow best practices before submitting PRs.
-
-Testing:
-
- Use [`cmp.Diff`](https://pkg.go.dev/github.com/google/go-cmp/cmp#Diff) instead of `reflect.Equal`, to provide useful comparisons.
- Define test cases as maps instead of slices to avoid dependencies on the running order.
-  Map key should be equal to the test case name.
-
-## Modify controller APIs
-
-If you want to modify Katib controller APIs, you have to
-generate deepcopy, clientset, listers, informers, open-api and Python SDK with the changed APIs.
-You can update the necessary files as follows:
-
-```bash
-make generate
-```
-
-## Controller Flags
-
-Below is a list of command-line flags accepted by Katib controller:
-
-| Name         | Type   | Default | Description                                                                                                                      |
-| ------------ | ------ | ------- | -------------------------------------------------------------------------------------------------------------------------------- |
-| katib-config | string | ""      | The katib-controller will load its initial configuration from this file. Omit this flag to use the default configuration values. |
-
-## DB Manager Flags
-
-Below is a list of command-line flags accepted by Katib DB Manager:
-
-| Name            | Type          | Default      | Description                                                         |
-| --------------- | ------------- | -------------| ------------------------------------------------------------------- |
-| connect-timeout | time.Duration | 60s          | Timeout before calling error during database connection             |
-| listen-address  | string        | 0.0.0.0:6789 | The network interface or IP address to receive incoming connections |
-
-## Katib admission webhooks
-
-Katib uses three [Kubernetes admission webhooks](https://kubernetes.io/docs/reference/access-authn-authz/extensible-admission-controllers/).
-
-1. `validator.experiment.katib.kubeflow.org` -
-   [Validating admission webhook](https://kubernetes.io/docs/reference/access-authn-authz/admission-controllers/#validatingadmissionwebhook)
-   to validate the Katib Experiment before the creation.
-
-1. `defaulter.experiment.katib.kubeflow.org` -
-   [Mutating admission webhook](https://kubernetes.io/docs/reference/access-authn-authz/admission-controllers/#mutatingadmissionwebhook)
-   to set the [default values](../pkg/apis/controller/experiments/v1beta1/experiment_defaults.go)
-   in the Katib Experiment before the creation.
-
-1. `mutator.pod.katib.kubeflow.org` - Mutating admission webhook to inject the metrics
-   collector sidecar container to the training pod. Learn more about the Katib's
-   metrics collector in the
-   [Kubeflow documentation](https://www.kubeflow.org/docs/components/katib/user-guides/metrics-collector/).
-
-You can find the YAMLs for the Katib webhooks
-[here](../manifests/v1beta1/components/webhook/webhooks.yaml).
-
-**Note:** If you are using a private Kubernetes cluster, you have to allow traffic
-via `TCP:8443` by specifying the firewall rule and you have to update the master
-plane CIDR source range to use the Katib webhooks
-
-### Katib cert generator
-
-Katib Controller has the internal `cert-generator` to generate certificates for the webhooks.
-
-Once Katib is deployed in the Kubernetes cluster, the `cert-generator` follows these steps:
-
- Generate the self-signed certificate and private key.
-
- Update a Kubernetes Secret with the self-signed TLS certificate and private key.
- Patch the webhooks with the `CABundle`.
-
-Once the `cert-generator` finished, the Katib controller starts to register controllers such as `experiment-controller` to the manager.
-
-You can find the `cert-generator` source code [here](../pkg/certgenerator/v1beta1).
-
-NOTE: the Katib also supports the [cert-manager](https://cert-manager.io/) to generate certs for the admission webhooks instead of using cert-generator.
-You can find the installation with the cert-manager [here](../manifests/v1beta1/installs/katib-cert-manager).
-
-## Implement a new algorithm and use it in Katib
-
-Please see [new-algorithm-service.md](./new-algorithm-service.md).
-
-## Katib UI documentation
-
-Please see [Katib UI README](../pkg/ui/v1beta1).
-
-## Design proposals
-
-Please see [proposals](./proposals).
-
-## Code Style
-
-### pre-commit
-
-Make sure to install [pre-commit](https://pre-commit.com/) (`pip install
-pre-commit`) and run `pre-commit install` from the root of the repository at
-least once before creating git commits.
-
-The pre-commit [hooks](../.pre-commit-config.yaml) ensure code quality and
-consistency. They are executed in CI. PRs that fail to comply with the hooks
-will not be able to pass the corresponding CI gate. The hooks are only executed
-against staged files unless you run `pre-commit run --all`, in which case,
-they'll be executed against every file in the repository.
-
-Specific programmatically generated files listed in the `exclude` field in
-[.pre-commit-config.yaml](../.pre-commit-config.yaml) are deliberately excluded
-from the hooks.

-# Security Policy
-
-## Supported Versions
-
-Kubeflow Katib versions are expressed as `vX.Y.Z`, where X is the major version,
-Y is the minor version, and Z is the patch version, following the
-[Semantic Versioning](https://semver.org/) terminology.
-
-The Kubeflow Katib project maintains release branches for the most recent two minor releases.
-Applicable fixes, including security fixes, may be backported to those two release branches,
-depending on severity and feasibility.
-
-Users are encouraged to stay updated with the latest releases to benefit from security patches and
-improvements.
-
-## Reporting a Vulnerability
-
-We're extremely grateful for security researchers and users that report vulnerabilities to the
-Kubeflow Open Source Community. All reports are thoroughly investigated by Kubeflow projects owners.
-
-You can use the following ways to report security vulnerabilities privately:
-
- Using the Kubeflow Katib repository [GitHub Security Advisory](https://github.com/kubeflow/katib/security/advisories/new).
- Using our private Kubeflow Steering Committee mailing list: ksc@kubeflow.org.
-
-Please provide detailed information to help us understand and address the issue promptly.
-
-## Disclosure Process
-
-**Acknowledgment**: We will acknowledge receipt of your report within 10 business days.
-
-**Assessment**: The Kubeflow projects owners will investigate the reported issue to determine its
-validity and severity.
-
-**Resolution**: If the issue is confirmed, we will work on a fix and prepare a release.
-
-**Notification**: Once a fix is available, we will notify the reporter and coordinate a public
-disclosure.
-
-**Public Disclosure**: Details of the vulnerability and the fix will be published in the project's
-release notes and communicated through appropriate channels.
-
-## Prevention Mechanisms
-
-Kubeflow Katib employs several measures to prevent security issues:
-
-**Code Reviews**: All code changes are reviewed by maintainers to ensure code quality and security.
-
-**Dependency Management**: Regular updates and monitoring of dependencies (e.g. Dependabot) to
-address known vulnerabilities.
-
-**Continuous Integration**: Automated testing and security checks are integrated into the CI/CD pipeline.
-
-**Image Scanning**: Container images are scanned for vulnerabilities.
-
-## Communication Channels
-
-For the general questions please join the following resources:
-
- Kubeflow [Slack channels](https://www.kubeflow.org/docs/about/community/#kubeflow-slack-channels).
-
- Kubeflow discuss [mailing list](https://www.kubeflow.org/docs/about/community/#kubeflow-mailing-list).
-
-Please **do not report** security vulnerabilities through public channels.

+# Developer Guide
+
+This developer guide is for people who want to contribute to the Katib project.
+If you're interesting in using Katib in your machine learning project,
+see the following user guides:
+
+- [Concepts](https://www.kubeflow.org/docs/components/katib/overview/)
+  in Katib, hyperparameter tuning, and neural architecture search.
+- [Getting started with Katib](https://kubeflow.org/docs/components/katib/hyperparameter/).
+- Detailed guide to [configuring and running a Katib
+  experiment](https://kubeflow.org/docs/components/katib/experiment/).
+
+## Requirements
+
+- [Go](https://golang.org/) (1.17 or later)
+- [Docker](https://docs.docker.com/) (20.10 or later)
+- [Java](https://docs.oracle.com/javase/8/docs/technotes/guides/install/install_overview.html) (8 or later)
+- [Python](https://www.python.org/) (3.9 or later)
+- [kustomize](https://kustomize.io/) (4.0.5 or later)
+
+## Build from source code
+
+Check source code as follows:
+
+```bash
+make build REGISTRY=<image-registry> TAG=<image-tag>
+```
+
+To use your custom images for the Katib components, modify
+[Kustomization file](https://github.com/kubeflow/katib/blob/master/manifests/v1beta1/installs/katib-standalone/kustomization.yaml)
+and [Katib Config](https://github.com/kubeflow/katib/blob/master/manifests/v1beta1/components/controller/katib-config.yaml)
+
+You can deploy Katib v1beta1 manifests into a Kubernetes cluster as follows:
+
+```bash
+make deploy
+```
+
+You can undeploy Katib v1beta1 manifests from a Kubernetes cluster as follows:
+
+```bash
+make undeploy
+```
+
+## Modify controller APIs
+
+If you want to modify Katib controller APIs, you have to
+generate deepcopy, clientset, listers, informers, open-api and Python SDK with the changed APIs.
+You can update the necessary files as follows:
+
+```bash
+make generate
+```
+
+## Controller Flags
+
+Below is a list of command-line flags accepted by Katib controller:
+
+| Name                            | Type                      | Default                       | Description                                                                                                            |

+## Workflow design
+
+Please see [workflow-design.md](./workflow-design.md).
+
+## Katib admission webhooks
+
+Katib uses three [Kubernetes admission webhooks](https://kubernetes.io/docs/reference/access-authn-authz/extensible-admission-controllers/).
+
+1. `validator.experiment.katib.kubeflow.org` -
+   [Validating admission webhook](https://kubernetes.io/docs/reference/access-authn-authz/admission-controllers/#validatingadmissionwebhook)
+   to validate the Katib Experiment before the creation.
+
+1. `defaulter.experiment.katib.kubeflow.org` -
+   [Mutating admission webhook](https://kubernetes.io/docs/reference/access-authn-authz/admission-controllers/#mutatingadmissionwebhook)
+   to set the [default values](../pkg/apis/controller/experiments/v1beta1/experiment_defaults.go)
+   in the Katib Experiment before the creation.
+
+1. `mutator.pod.katib.kubeflow.org` - Mutating admission webhook to inject the metrics
+   collector sidecar container to the training pod. Learn more about the Katib's
+   metrics collector in the
+   [Kubeflow documentation](https://www.kubeflow.org/docs/components/katib/experiment/#metrics-collector).
+
+You can find the YAMLs for the Katib webhooks
+[here](../manifests/v1beta1/components/webhook/webhooks.yaml).
+
+**Note:** If you are using a private Kubernetes cluster, you have to allow traffic
+via `TCP:8443` by specifying the firewall rule and you have to update the master
+plane CIDR source range to use the Katib webhooks
+
+### Katib cert generator
+
+Katib uses the custom `cert-generator` [Kubernetes Job](https://kubernetes.io/docs/concepts/workloads/controllers/job/)
+to generate certificates for the webhooks.
+
+Once Katib is deployed in the Kubernetes cluster, the `cert-generator` Job follows these steps:
+
+- Generate the self-signed CA certificate and private key.
+
+- Generate public certificate and private key signed with the key generated in the previous step.
+
+- Create a Kubernetes Secret with the signed certificate. Secret has
+  the `katib-webhook-cert` name and `cert-generator` Job's `ownerReference` to
+  clean-up resources once Katib is uninstalled.
+
+  Once Secret is created, the Katib controller Deployment spawns the Pod,
+  since the controller has the `katib-webhook-cert` Secret volume.
+
+- Patch the webhooks with the `CABundle`.
+
+You can find the `cert-generator` source code [here](../cmd/cert-generator/v1beta1).
+
+## Implement a new algorithm and use it in Katib
+
+Please see [new-algorithm-service.md](./new-algorithm-service.md).
