-# Simple user authentication using python framework - FastAPI, MongoDM, Docker Compose
-For usage first you have to git clone the files:
-- git clone https://github.com/AtamanKit/fastapi_users_docker.git
+# User authentication using FastAPI (a python frameworks), MongoDM (for database), Docker Compose (for deployment)
+## How to start the application
+**Watch the video** (below the video are the commands on how to start the application):
+* https://www.youtube.com/watch?v=Bw5rQXgvHYc
+
+**The commands on how to start the application:**
+
+First you have to git clone the files by entering in your terminal:
+```
+$ git clone https://github.com/AtamanKit/fastapi_users_docker.git
+```  
+Then start the application by enterig:
+```
+$ docker-compose up -d
+```
+The above command will both create the images and start the containers (2 images and 2 containers - one for the application and one for the MongoDB database).
+For visualizing the application, open up your browser and enter:
+
+* http://127.0.0.1/docs
+
+In the application you'll have six sections:
+* For creating users (3 roles are acceptable only: "admin", "dev", "simple mortal"), you'll see an error if not respecting the rule;
+* For creating tokens by entering user's credentials;
+* For listing the users;
+* For watching the current user (only if authenticated);
+* For modifying user properties (only if authenticated with admin role);
+* For deleting the user.
+To see the runing containers in docker enter in the terminal:
+```
+$ docker ps
+```
+To see the database and collection created (database name is: myTestDB, collection: users) enter in your terminal:
+```
+$ docker exec -it <container-id> bash
+```
+
+## Configuration and file structure
+Our file structure is:
+```
+.
+├── app
+│   ├── Dockerfile
+│   ├── __init__.py
+│   ├── main.py
+│   ├── requirements.txt
+│   └── src
+│       ├── __init__.py
+│       ├── dependecies.py
+│       ├── models.py
+│       ├── routers.py
+│       └── settings.py
+└── docker-compose.yml
+```
+In the app directory in ```main.py``` file we make all the dependencies and routers importing from the same name files located in ```src``` directory.
+
+```src``` directory is the one that containes all the needed pydantic models (models.py), database and authentication variables (settings.py). 
+
+Authentication is made by using ```bearer``` scheme with ```token``` creation and usage.
+
+```dependecies.py``` is the file containing authentication fucntions (I also made an authentication middleware located in ```main.py``` file in the root directory using ```basic``` scheme that serves only as an example purpose).
