 ## Deployment
 
-Simply run this compose.yml:
+PortNote uses docker compose for deployment. It is crucial
+to set up some secrets for the environment to make your
+deployment work. One could do that by creating a `.env`
+file with following content:
+
+```dotenv
+JWT_SECRET=# Replace with a secure random string
+USER_SECRET=# Replace with a secure random string
+LOGIN_USERNAME=# Replace with a username
+LOGIN_PASSWORD=# Replace with a custom password
+```
+
+To quickly generate such file, one can execute a following
+command:
+
+> Note: it will overwrite the .env file if it already exists
+
+```sh
+echo """
+JWT_SECRET=$(openssl rand -base64 32)
+USER_SECRET=$(openssl rand -base64 32)
+LOGIN_USERNAME=some_user
+LOGIN_PASSWORD=some_password
+""" > .en
+```
+
+Adjust the values to your needs and then run the following
+[compose.yaml](compose.yml):
+
 ```yml
 services:
   web:
     image: haedlessdev/portnote:latest
     ports:
