+
+A sample App using flask and redis
+
+## Setup application
+
+1. Clone the repository and move to flask-redis folder
+2. Create a .env file and copy-paste below credentials:
+
+```bash
+REDIS_HOST=redis
+REDIS_PORT=6379
+```
+
+# Installing Redis
+
+```sh
+brew install redis
+```
+If homebrew is not installed, then go to https://brew.sh/ and install it.
+
+```bash
+git clone https://github.com/keploy/samples-typescript && cd samples-typescript/flask-redis
+
+# Install the dependencies
+pip3 install -r requirements.txt
+```
+
+# Installing Keploy
+
+Let's get started by setting up the Keploy alias with this command:
+
+```sh
+curl -O https://raw.githubusercontent.com/keploy/keploy/main/keploy.sh && source keploy.sh
+```
+
+## Using Keploy :
+
+There are 2 ways you can run this sample application.
+
+1. [Natively on Linux/WSL](#natively-on-ubuntuwsl)
+2. [Using Docker](#running-sample-app-using-docker)
+
+# Natively on Ubuntu/WSL
+
+## Let's install certificates
+
+1. **Install required packages:**
+
+   ```sh
+   sudo apt-get install -y --no-install-recommends ca-certificates curl
+   ```
+
+   This command installs necessary packages without additional recommended packages.
+
+2. **Download CA certificate:**
+
+   ```sh
+   curl -o ca.crt https://raw.githubusercontent.com/keploy/keploy/main/pkg/core/proxy/asset/ca.crt
+   ```
+
+   This command downloads the CA certificate to `ca.crt`.
+
+3. **Download setup script:**
+
+   ```sh
+   curl -o setup_ca.sh https://raw.githubusercontent.com/keploy/keploy/main/pkg/core/proxy/asset/setup_ca.sh
+   ```
+
+   This command downloads the setup script to `setup_ca.sh`.
+
+4. **Make the setup script executable:**
+
+   ```sh
+   chmod +x setup_ca.sh
+   ```
+
+   This command changes the permissions of `setup_ca.sh` to make it executable.
+
+5. **Run the setup script:**
+
+   ```sh
+   source ./setup_ca.sh
+   ```
+
+   This command executes the setup script in the current shell.
+
+6. **Start the redis server:**
+   ```sh
+   redis-server
+   ```
+   This command starts the redis server.
+
+## Capture the test cases
+
+1. **Start recording tests:**
+   ```bash
+   sudo -E env "PATH=$PATH" keploybin record -c 'python3 app.py'
+   ```
+
+## Let's Generate the test cases
+
+Make API Calls using Hoppscotch, Postman or cURL command. Keploy will capture those calls to generate test suites containing test cases and data mocks.
+
+1. Refer to flask-redis/api.txt to make api calls.
+
+2. **Observe terminal output:**
+   Let's go ahead and create a few more test cases for different endpoints!
+
+## Running the test cases
+
+1. **Start the application:**
+
+   ```bash
+   python3 app.py
+   ```
+
+2. **Run the recorded tests:**
+
+   ```bash
+   sudo -E env "PATH=$PATH" keploybin test -c 'python3 app.py' --delay 10
+   ```
+
+3. **Observe test run results:**
+   _Voila!! Our test cases have passed 🌟_
+
+---
+
+# Using Docker
+
+Since we have to setup our app using docker(make sure your docker is running)
+
+## Create a custom network for Keploy since we are using the Docker
+
+```bash
+docker network create keploy-network
+```
+
+## Capture the testcases
+
+We will run the keploy in record mode with docker-compose to start our application:-
+
+```bash
+keploy record -c "sudo docker-compose up" --containerName "flask-web"
+
+```
+
+#### Let's generate the testcases.
+
+Make API Calls using [Hoppscotch](https://hoppscotch.io), [Postman](https://postman.com) or curl command. Keploy with capture those calls to generate the test-suites containing testcases and data mocks.
+
+1. Refer to flask-redis/api.txt to make api calls
+
+## Running the testcases
+
+```bash
+keploy test -c 'sudo docker-compose up' --containerName "flask-web" --delay 10
+```
+
+_Voila!! Our testcases has passed 🌟_
