 # Project Guide
 
-## Setup
+## Scope
+
+The scope of this project is to set up a backend application hosted on an Amazon EC2 instance, configure the necessary networking components using AWS services, 
+and manage access through AWS Identity and Access Management (IAM).  
+The project aims toward deploying and managing a backend application in a cloud environment, focusing on the following core objectives:
+
+- Setting up an EC2 instance for hosting the backend application.
+- Creating and configuring a Virtual Private Cloud (VPC) and API Gateway.
+- Introducing IAM and policies for secure access management.
 
 ## Introduction
 
+This project guide aims to walk you through the process of setting up a backend application on an Amazon EC2 instance, configuring essential networking components, and managing access using IAM. 
+By the end of this project, you will have a functional backend application hosted on AWS, accessible via an API Gateway, and secured with IAM policies.
+
+This project serves as a backend service designed to handle API requests using the following technologies:
+
+- Language: C#
+- Framework: ASP.NET Core
+- Database: PostgreSQL
+
 ## Technical Designs
 
-## Technical Descriptions
+### EC2 Instance Setup
+1. **Instance Creation:**
+- Launch an EC2 instance using the AWS Management Console.
+- Select an appropriate Amazon Machine Image (AMI) and instance type.
+- Configure instance details, including VPC and subnet settings.
+- Set up security groups to allow necessary traffic (HTTP, HTTPS, SSH).
+2. **Instance Connection:**
+- Connect to the EC2 instance using SSH.
+- Install required dependencies for the backend application.
+3. **Application Deployment:**
+- Transfer application files to the EC2 instance.
+- Deploy and start the backend application.
+### Networking Configuration
+1. **VPC Creation:**
+-Create a VPC with a specified CIDR block.
+-Set up subnets within the VPC.
+2. **Internet Gateway and Route Table:**
+-Attach an Internet Gateway to the VPC.
+-Configure route tables to direct traffic to the Internet Gateway.
+3. **API Gateway Setup:**
+-Create a REST API using API Gateway.
+-Configure HTTP methods and integrate with the backend application hosted on the EC2 instance.
+### IAM and Policies
+1. **IAM Basics:**
+- Create IAM users and assign roles.
+- Understand and apply IAM policies to control access to AWS resources.
+2. **Role Assignment:**
+- Create IAM roles for EC2 instances to access other AWS services.
+- Attach policies to roles and assign them to EC2 instances.

+## Technical Descriptions
+### EC2 Instance Setup
+- **Create an EC2 Instance:** Use the AWS Management Console to launch an instance, selecting an AMI like Amazon Linux 2 or Ubuntu Server. Choose an instance type (e.g., t2.micro for free-tier), configure instance details, and set up security groups to allow HTTP, HTTPS, and SSH access.
+- **Connect to the EC2 Instance:** Use SSH to connect to the instance and install necessary dependencies such as the .NET SDK or Nginx.
+- **Deploy Your Backend Application:** Transfer your application files to the EC2 instance using scp, extract the files, and start the application using the appropriate commands.
+### Networking Configuration
+- **Create a VPC:** In the AWS Management Console, create a VPC with a CIDR block (e.g., 10.0.0.0/16) and set up subnets in different availability zones.
+- **Configure Route Table and Internet Gateway:** Attach an Internet Gateway to the VPC and configure route tables to direct traffic to the Internet Gateway for public subnets.
+- **Create and Configure API Gateway:** Set up a REST API in API Gateway, define HTTP methods, and integrate with the backend application using the public IP or domain of the EC2 instance.
+### IAM and Policies
+- **Understand IAM Basics:** Navigate to the IAM service, create users, and assign roles. Attach policies to users based on their roles, such as AmazonEC2FullAccess or AmazonS3ReadOnlyAccess.
+- **Create and Use IAM Roles:** Create IAM roles for EC2 instances to access other AWS resources, attach appropriate policies, and assign the roles to EC2 instances.
