+# Kubot - Parallelizing Robot Scripts over Kubernetes Workloads
 
-Parallel robot execution on Kubernetes workloads
+Kubot is a command-line interface (CLI) program designed to parallelize and distribute the execution of Robot Framework
+scripts over Kubernetes workloads. It enables efficient and scalable execution of robot scripts using the power of
+Kubernetes.

-## Introduction
-
-This project provides a method for parallelizing the executions of robot scripts over Kubernetes workloads.
-
-## Getting Started
-
-To get started with this project, you will need to have access to a Kubernetes cluster as well as the following
-prerequisites:
-
-### Prerequisites
-
-- kubectl
+- **Parallel Execution**: Kubot utilizes Kubernetes workloads to parallelize the execution of Robot Framework scripts,
+  significantly reducing the overall execution time.
+- **Flexible Workspace**: You can specify the workspace path where your robot scripts are located, allowing you to
+  easily manage and organize your test suites.
+- **Batch Execution**: Define the batch size for parallel execution, controlling the number of scripts executed
+  concurrently.
 
 ## Installation
 
-```
-TODO implement here
+To install Kubot, you need to have Go programming language and Docker installed on your machine. Then, run the following
+command:
+
+```bash
+go get github.com/yusufcanb/kubot
 ```
 
 ## Usage
 
+```bash
+kubot exec --workspace=/path/to/scripts \
+           --name="Daily UI Scan" \
+           --batchsize=15 \
+           --namespace=kubot \
+           --image=docker.io/marketsquare/robotframework-browser:latest
 ```
-kubot --workspace . \
-      --image docker.io/kubot:basic \
-      --namespace [your-namespace] \
-      --selector [robot-selector]
-      --output [output-directory]
-```
 
-## Configuration
+Here are the environment variables you can configure the advanced Pod spec;
+
+## Flags
+
+- **--workspace (-w)**: Specifies the path to the workspace containing your robot scripts.
+- **--name (-n)**: Sets the top-level suite name for logs and reports generated by the execution.
+- **--batchsize (-b)**: Defines the execution batch size, controlling the number of scripts executed concurrently. The
+- default value is 25.
+- **--namespace**: Specifies the Kubernetes namespace where the workloads will be created.
+- **--image (-i)**: Sets the Docker image to be used for the execution of robot scripts.
+- **--selector (-s)**: Allows you to specify a script selector, such as tasks/*, to execute specific scripts or groups
+  of
+  scripts within your workspace.
+
+## Workload Configuration
 
 Here is the configuration parameters you can use;
 
-| Name          | Description          | Default |
-|---------------|----------------------|---------|
-| POD_CPU_LIMIT | CPU limit per pod    | 10      | 
-| POD_MEM_LIMIT | Memory limit per Pod | 128 Mb  |
+| Name                     | Description            | Default |
+|--------------------------|------------------------|---------|
+| KUBOT_POD_CPU_REQUEST    | CPU request per pod    | 250m    | 
+| KUBOT_POD_MEMORY_REQUEST | Memory request per Pod | 128Mi   |
+| KUBOT_POD_CPU_LIMIT      | Memory limit per Pod   | 250m    |
+| KUBOT_POD_MEMORY_LIMIT   | Memory limit per Pod   | 256Mi   |

+
+## Acknowledgments
+
+Kubot was inspired by the need for efficient execution of Robot Framework scripts in parallel over Kubernetes workloads.
+I would like to thank the open-source community for their valuable contributions and the Robot Framework project for
+providing a powerful automation framework.
