 # Usage
 
-## Local
+## Prerequisites
+Python 3.8+
+Poetry for managing project dependencies and virtual environment.
 
-For running the serice locally, natigate to the backend directory and run the following command:
+## Installation and setup
+1. Clone this directory and navigate into the project directory.
 
-```bash
+```commandline
-uvicorn main:app --reload
+git clone https://github.com/Hestia-Homes/Model.git
+cd backend
 ```
 
+2. For environment management, I'm using conda with pycharm which is a convenient setup for development
+on a mac M1 however using tools such as poetry or pipenv is also fine.
+
+For example, to install conda and create a virtual environment for this project, run the following commands:
+
+```commandline
+conda create -n backend python=3.10
+conda activate backend
+```
+
+then enter the virtual environment and install the dependencies using conda.
+
+```commandline
+conda install --file requirements/base.txt
+```
+
+3. Duplicate .env.example and rename it to .env
+```commandline
+cp .env.example .env
+```
+
+4. Open .env and fill in the required environment variables.
+
+## Running the Application
+
+from within  the application you can run with the following command:
+
+```commandline
+uvicorn app.main:app --reload
+```
+
+You application will be available at the designated url
+
+## API Documentation
+
+FastAPI automatically generates interactive API documentation for your application. To access the docs, start your 
+server and visit <yourlocalurl>/docs in your browser. Alternatively, you can go to
+<yourlocalurl>/redoc to view the documentation in the ReDoc format.
+
+## Testing
+To run tests, run the following command from the root of the project directory:
+
+```commandline
+pytest
+```
+

 ### Thoughts for authenticating the frontend with the backend
 To provide secure communication between your frontend Next.js application and your backend FastAPI service, you have several options. Here are a few popular approaches:
