+# README.md - `oc-workflow` Helm Chart
+
+This document describes the different tags found in the `values.yml` file used in the Helm chart for the `oc-workflow` component.
+
+## Tags in the `values.yml` file
+
+### `replicaCount`
+- **Description**: Defines the number of replicas for the deployment. A replica represents an instance of the application that will be deployed.
+- **Example**: `1` means a single instance of the `oc-workflow` service will be deployed.
+
+### `image.repository`
+- **Description**: Specifies the URL of the Docker image registry where the `oc-workflow` component image is stored.
+- **Example**: `registry.dev.svc.cluster.local:5000/oc-workflow` refers to a local registry hosted within the `cluster.local` network.
+
+### `image.tag`
+- **Description**: Indicates the tag of the Docker image to use. Typically, this could be a specific version or `latest` to always pull the latest version.
+- **Example**: `latest` means the most recent version of the image will be used.
+
+### `image.pullPolicy`
+- **Description**: Defines the image pull policy. The possible options are:
+  - `Always`: Always pull the image.
+  - `IfNotPresent`: Pull the image only if it is not already present on the node.
+  - `Never`: Never pull the image.
+- **Example**: `IfNotPresent` means the image will only be pulled if it is not already present on the node.
+
+### `env.mongoDatabase`
+- **Description**: Defines the name of the MongoDB database the application will connect to.
+- **Example**: `DC_myDC` refers to the MongoDB database used by the application.
+
+### `env.mongoUrl`
+- **Description**: Specifies the connection URL for MongoDB used by the application.
+- **Example**: `mongodb://toto:27017` indicates that the application will connect to the MongoDB instance hosted at `toto` on port `27017`.
+
+### `service.type`
+- **Description**: Defines the type of Kubernetes service. Possible types include:
+  - `ClusterIP`: The service is only accessible within the cluster.
+  - `NodePort`: The service is accessible via a specific port on all cluster nodes.
+  - `LoadBalancer`: The service is exposed via an external Load Balancer.
+- **Example**: `ClusterIP` means the service will only be accessible within the Kubernetes cluster.
+
+### `service.port`
+- **Description**: Specifies the port on which the service will be exposed within the cluster.
+- **Example**: `8088` means the service will be accessible on port `8088`.
+
+### `service.targetPort`
+- **Description**: Defines the port on which the application listens inside the container.
+- **Example**: `8080` means the application listens on port `8080` within the container.
+
+### `resources.limits.cpu`
+- **Description**: Specifies the maximum amount of CPU (in millicores) allocated to the container.
+- **Example**: `500m` means the container can use up to 0.5 CPU (or 50% of a full CPU core).
+
+### `resources.limits.memory`
+- **Description**: Specifies the maximum amount of memory (in MiB) allocated to the container.
+- **Example**: `512Mi` means the container can use up to 512 MiB of memory.
+
+### `resources.requests.cpu`
+- **Description**: Defines the guaranteed amount of CPU (in millicores) for the container. Kubernetes will ensure this amount is always available.
+- **Example**: `250m` means the container will have at least 0.25 CPU (or 25% of a full CPU core).
+
+### `resources.requests.memory`
+- **Description**: Defines the guaranteed amount of memory (in MiB) for the container. Kubernetes will reserve this memory for the container.
+- **Example**: `256Mi` means the container will have at least 256 MiB of memory.
+
+## Conclusion
+
+This `values.yml` file allows configuring the deployment settings for the `oc-workflow` component. Each tag plays a specific role in defining the Docker image, service configuration, and resource allocation for the container within the Kubernetes cluster.
