 # Chefies Backend
-Chefies is an application
+Backend of Chefies Project made with Python and FastAPI. This is being made as a requirements to complete the Bangkit capstone project.
+
+## Development Environment Installation
+
+### Requirements
+Before installing, you need python and poetry to be installed in your computer. You can follow these guidelines:
+- [Python Installation](https://www.python.org/downloads/)
+- [Poetry Installation](https://python-poetry.org/docs/)
+
+### Installing Dependencies
+In the project root directory where `pyproject.toml` and `poetry.lock` is located, run:
+```
+poetry install
+```
+
+This command will install required dependencies for running the backend application.
+
+### Firebase Emulators
+This project requires several GCP technologies such as Cloud Storage and Cloud Firestore.
+You can use firebase emulators to run them in local. Follow this 
+[firebase emulators installation guideline](https://firebase.google.com/docs/emulator-suite/install_and_configure).
+
+To start the emulators, run the command below.
+```
+firebase emulators:start
+```
+
+### Running the Backend
+Before running the FastAPI backend, ensure that you have included these environment variables in the `.env` file:
+- `FIRESTORE_EMULATOR_HOST`: The host of firestore emulator. Using the given `firebase.json` config, the value must be `localhost:8080`
+- `STORAGE_EMULATOR_HOST`: The URL of storage emulator. Using the given `firebase.json` config, the value must be `http://localhost:9199`
+- `GOOGLE_APPLICATION_CREDENTIALS` or `SERVICE_ACCOUNT_PATH` (choose one): Path of the service account key. Example: `keys/credentials.json`
+- `STORAGE_BUCKET`: Storage bucket name in Cloud Storage. Example: `chefies-dev.appspot.com`
+
+Now, you can run the backend in port 8000 using this command:
+```
+poetry run fastapi run cefies/app.py --port 8000
+```
+
+## Deployment
+We have created a `Dockerfile` for deploying the application in Docker containers. To build the image, you can use:
+```
+docker build -t <image-name> .
+```
+
+After building the image, you can run it by using:
+```
+docker run --name <container-name> -e PRODUCTION=1 -e GOOGLE_APPLICATION_CREDENTIALS=<credentials-json-path> -d --restart always -p 9000:80 <image-name>
+```
+
+Note that the env `FIRESTORE_EMULATOR_HOST` and `STORAGE_EMULATOR_HOST` is not required as you are not using firebase emulators.
