 ##  A Toolkit for Modeling and Simulation of Quantum Computing Environments
 
-As quantum computers become increasingly accessible through 
-cloud services and potentially edge networks, the demand for efficient resource 
-management strategies and service models has grown. 
-iQuantum is a pioneering simulation toolkit (based on CloudSim) designed to model hybrid quantum-classical
-computing environments, enabling researchers to prototype and evaluate system design and
-resource management algorithms. iQuantum addresses the challenges posed by the limited 
-availability and accessibility of quantum resources, catalyzing research in 
-quantum software and systems.
+As quantum computers become increasingly accessible through
+cloud services and potentially extending to the edge networks in the future, the demand for efficient resource
+management strategies is paramount to ensure the efficient utilization of quantum computing resources.
+However, the limitations of employing practical quantum computing resources and the lack of
+quantum environments modeling toolkits have hindered the design and evaluation of quantum resource management policies.
+To address this challenge, we propose iQuantum, a lightweight and versatile discrete-event modeling and simulation toolkit (based on CloudSim)
+for quantum computing environments. iQuantum provides a set of quantum computing entities can be customized and extended to
+support a wide range of different hybrid quantum computing environments, support research in quantum resource management, and prototyping of quantum computing systems.

-## Download and Using
+## Setup and Using
 Please refer to the [Release page](https://github.com/Cloudslab/iQuantum/releases) to access the latest release of iQuantum (1.0.0-beta).
 The downloaded package contains the main jar file (`iquantum-1.0.0-beta.jar`) and the entire source code of iQuantum.
-### Prerequisites 
+### Prerequisites
 - Java SDK 17+ ([corretto-17](https://docs.aws.amazon.com/corretto/latest/corretto-17-ug/downloads-list.html) is recommended).
 - [Apache Maven](https://maven.apache.org/download.cgi) (All library management and build automation in iQuantum are handled by Maven; version 3.9+ is recommended)
 - [IntelliJ IDEA](https://www.jetbrains.com/idea/) (latest version, 2023+) is highly recommended for customizing the source code (e.g., resource management policies or other entities)
 
+### Building from Source
+To build iQuantum from source, please follow these steps:
+1. Clone the iQuantum repository to your local machine.
+2. Open the project in IntelliJ IDEA.
+3. Build the project using Maven.
+4. The built jar file (`iquantum-1.0.0-beta.jar`) will be located in the `/modules/iquantum/target` folder.
+5. Add the built jar file to your project's classpath.
+6. You are ready to use iQuantum in your project.
+
+### Modeling and Simulation Workflow
+The simulation workflow of iQuantum is illustrated in the following figure.
+<img alt="iQuantum Workflow" src="documentation/figures/iQuantumFlow.png" title="iQuantum Workflow" width="400"/>
+1. **Modeling**: The user defines the quantum computing environment (e.g., quantum datacenters, quantum computers, quantum tasks, and quantum brokers) using the iQuantum entities.
+   - Quantum tasks and quantum nodes can be modeled manually or automatically by importing from dataset (.csv), which can be generated from QASM files for quantum tasks (e.g., using [MQT Bench](https://www.cda.cit.tum.de/mqtbench/)) and system calibration datasheet (e.g., from [IBM Quantum](https://quantum-computing.ibm.com/lab/docs/iql/manage/systems/configuration)).
+   - Resource management policies (scheduling, mapping, backend selection, and offloading) can be customized by extending the corresponding classes (in `org.iquantum.policies` package).
+2. **Environment Setup**: The user defines the simulation parameters and start the simulation. 
+3. **Simulation**: The discrete-event simulation engine of iQuantum simulates the events in the quantum computing environment (e.g., task submission, task execution, task completion, etc.), based on the defined resource management policies.
+4. **Generating the results**: The simulation results (e.g., task execution time, backend allocation, cost of execution, etc.) can be shown or exported to a .csv file for further analysis.
+
 ### Examples of Operation
 Several examples that demonstrate the use of iQuantum can be found in the `org.iquantum.examples` package, located in the `/modules/iquantum-examples` folder.
