+# Todo App - Setup and Execution Guide
+
+This repository contains a containerized Django Todo application. Follow the steps below to set up and run the application.
+
+## 1. Prerequisites
+
+Before you begin, ensure you have Docker installed on your machine:
+
+**Link:** https://www.docker.com/products/docker-desktop/
+
+Verify your installation by running:
+
+```bash
+docker --version
+```
+
+## 2. Docker Hub Repository
+
+The pre-built image is hosted on Docker Hub:
+
+**Link:** https://hub.docker.com/repository/docker/jijuzo/todoapp
+
+## 3. Building and Running the Container
+ 
+There are two ways to get your Todo application up and running:
+ 
+- **Option A (Pull and Run):** Use the pre-built image from Docker Hub if you don't need to make any changes to the source code.
+- **Option B (Build and Run):** Clone the repository and build the image locally from the Dockerfile if you want to customize the application or work with the source code.
+
+Select the option that best fits your workflow.
+ 
+## 4. Option A: Pull and Run 
+ 
+### Pull the image:
+ 
+```bash
+docker pull jijuzo/todoapp:1.0.0
+```
+ 
+### Run the container:
+ 
+```bash
+docker run -d -p 8080:8080 --name <your-container-name> jijuzo/todoapp:1.0.0
+```
+ 
+## 5. Option B: Build and Run
+ 
+### Clone the repository:
+ 
+```bash
+git clone https://github.com/Jijuzo/devops_todolist.git
+cd devops_todolist
+git checkout dev
+```
+ 
+### Build the image:
+ 
+```bash
+docker build -t todoapp:1.0.0 .
+```
+ 
+### Run the container:
+ 
+```bash
+docker run -d -p 8080:8080 --name <your-container-name> todoapp:1.0.0
+```
+ 
+## 6. Accessing the Application
+ 
+Once the container is running, the application will be available at:
+ 
+**URL:** http://localhost:8080
