-# ACM
+# codecoapp-operator
+This is the project for the CODECO ACM operator.  
+**Note:** It is in PoC mode - current content of the CRD and the operator behavior
+is still expetimental
 
+## Description
+This projects is used for the development of the CODECO ACM operator. 
+
+The CODECO ACM operatore is the main entry point to the CODECO platform. It serves
+2 types of users, and provides 2 different CRDs, one per user.
+* _Application developer_ (aka _cluster user_) - This is a user that deploys an 
+application on the CODECO platforme. The CRD for the application deployment is 
+*CodecoApp*.
+* _Cluster admin_ - TBD
+
+## Getting Started
+You’ll need a Kubernetes cluster to run against. You can use [KIND](https://sigs.k8s.io/kind) to get a local cluster for testing, or run against a remote cluster.  
+**Note:** Your controller will automatically use the current context in your kubeconfig file (i.e. whatever cluster `kubectl cluster-info` shows).
+
+### Running on the cluster
+1. Install Instances of Custom Resources:
+
+```sh
+kubectl apply -f config/samples/
+```
+
+2. Build and push your image to the location specified by `IMG`:
+
+```sh
+make docker-build docker-push IMG=<some-registry>/codecoapp-operator:tag
+```
+**Note I:** This is required only after code changes in the operator.   
+**Note II:** For _kind_ k8s cluster there is a need to push also the controller to a registry, 
+do the following for loading it (a one time step) - this is needed if the cluster can't
+access images on _localhost_ 
+
+    > docker push localhost/controller:latest <some-registry>/controller
+    
+3. Deploy the controller to the cluster with the image specified by `IMG`:
+
+```sh
+make deploy IMG=<some-registry>/controller:latest
+```
+
+### Uninstall CRDs
+To delete the CRDs from the cluster:
+
+```sh
+make uninstall
+```
 
+### Undeploy controller
+UnDeploy the controller from the cluster:
 
+```sh
+make undeploy
+```
+
+## Contributing
+// TODO(user): Add detailed information on how you would like others to contribute to this project
+
+### How it works
+This project aims to follow the Kubernetes [Operator pattern](https://kubernetes.io/docs/concepts/extend-kubernetes/operator/).
+
+It uses [Controllers](https://kubernetes.io/docs/concepts/architecture/controller/),
+which provide a reconcile function responsible for synchronizing resources until the desired state is reached on the cluster.
+
+### Test It Out (Development only, not a real K8s cluster deployment)
+1. Install the CRDs into the cluster:
+
+```sh
+make install
+```
+
+2. Run your controller (this will run in the foreground, so switch to a new terminal if you want to leave it running):
+
+```sh
+make run
+```
+
+**NOTE:** You can also run this in one step by running: `make install run`
+
+### Modifying the API definitions
+If you are editing the API definitions, generate the manifests such as CRs or CRDs using:
+
+```sh
+make manifests
+```
+
+**NOTE:** Run `make --help` for more information on all potential `make` targets
+
+More information can be found via the [Kubebuilder Documentation](https://book.kubebuilder.io/introduction.html)

+# From Gitlab README info
 ## Getting started
 
 To make it easy for you to get started with GitLab, here's a list of recommended next steps.
@@ -42,51 +148,3 @@ Use the built-in continuous integration in GitLab.

-# Editing this README
-
-When you're ready to make this README your own, just edit this file and use the handy template below (or feel free to structure it however you want - this is just a starting point!). Thank you to [makeareadme.com](https://www.makeareadme.com/) for this template.
-
-## Suggestions for a good README
-Every project is different, so consider which of these sections apply to yours. The sections used in the template are suggestions for most open source projects. Also keep in mind that while a README can be too long and detailed, too long is better than too short. If you think your README is too long, consider utilizing another form of documentation rather than cutting out information.
-
-## Name
-Choose a self-explaining name for your project.
-
-## Description
-Let people know what your project can do specifically. Provide context and add a link to any reference visitors might be unfamiliar with. A list of Features or a Background subsection can also be added here. If there are alternatives to your project, this is a good place to list differentiating factors.
-
-## Badges
-On some READMEs, you may see small images that convey metadata, such as whether or not all the tests are passing for the project. You can use Shields to add some to your README. Many services also have instructions for adding a badge.
-
-## Visuals
-Depending on what you are making, it can be a good idea to include screenshots or even a video (you'll frequently see GIFs rather than actual videos). Tools like ttygif can help, but check out Asciinema for a more sophisticated method.
-
-## Installation
-Within a particular ecosystem, there may be a common way of installing things, such as using Yarn, NuGet, or Homebrew. However, consider the possibility that whoever is reading your README is a novice and would like more guidance. Listing specific steps helps remove ambiguity and gets people to using your project as quickly as possible. If it only runs in a specific context like a particular programming language version or operating system or has dependencies that have to be installed manually, also add a Requirements subsection.
-
-## Usage
-Use examples liberally, and show the expected output if you can. It's helpful to have inline the smallest example of usage that you can demonstrate, while providing links to more sophisticated examples if they are too long to reasonably include in the README.
-
-## Support
-Tell people where they can go to for help. It can be any combination of an issue tracker, a chat room, an email address, etc.
-
-## Roadmap
-If you have ideas for releases in the future, it is a good idea to list them in the README.
-
-## Contributing
-State if you are open to contributions and what your requirements are for accepting them.
-
-For people who want to make changes to your project, it's helpful to have some documentation on how to get started. Perhaps there is a script that they should run or some environment variables that they need to set. Make these steps explicit. These instructions could also be useful to your future self.
-
-You can also document commands to lint the code or run tests. These steps help to ensure high code quality and reduce the likelihood that the changes inadvertently break something. Having instructions for running tests is especially helpful if it requires external setup, such as starting a Selenium server for testing in a browser.
-
-## Authors and acknowledgment
-Show your appreciation to those who have contributed to the project.
-
-## License
-For open source projects, say how it is licensed.
-
-## Project status
-If you have run out of energy or time for your project, put a note at the top of the README saying that development has slowed down or stopped completely. Someone may choose to fork your project or volunteer to step in as a maintainer or owner, allowing your project to keep going. You can also make an explicit request for maintainers.
