 ## Installation
 
 * First of all clone the project:
-```
+
+```bash
 git clone https://github.com/EngRobot33/ZED.git
 ```
+
 * Then, we need a virtual environment you can create like this:
-```
+
+```bash
 virtualenv venv
 ```
+
 * Activate it with the command below:
-```
+
+```bash
 source venv/bin/activate
 ```
+
 * After that, you must install all the packages in `requirements.txt` file in project directory:
-```
+
+```bash
 pip install -r requirements.txt
 ```
+
 * You should install PostgreSQL and its dependecies:
+
   ```shell
   sudo apt update
   sudo apt install python3-pip python3-dev libpq-dev postgresql postgresql-contrib
   ```
+
 * Now setup your database in PostgreSQL shell:
   * Open PostgreSQL shell:
+
     ```shell
     sudo -u postgres psql
     ```
+
   * Create database:
+
     ```sql
     CREATE DATABASE <database_name>;
     ```
+
   * Create user:
+
     ```sql
     CREATE USER <database_user> WITH PASSWORD '<database_password>';
     ```
+
   * Grant all privileges to zed database user:
+
     ```sql
     GRANT ALL PRIVILEGES ON DATABASE <database_name> TO <database_user>;
     ```
 
 * Create a `.env` file in root directory and add your created config like `.env.sample`:
+
 ```python
 SECRET_KEY = 'Your secret key generated by https://djecrety.ir'
 DEBUG = 'Project debug status'

 * Create a `.env` file in root directory and add your created config like `.env.sample`:
+
 ```python
 SECRET_KEY = 'Your secret key generated by https://djecrety.ir'
 DEBUG = 'Project debug status'
 ALLOWED_HOSTS = 'Host/Domain names list that this site can serve for e.g ['*'] allows all hosts'

+DB_NAME = '<database_name>'
+DB_USER = '<database_user>'
+DB_PASS = '<database_password>'
+DB_HOST = db
+DB_PORT = <database_port>
 ```
 
-* That's finished! Now you can run the project:
+* Make sure to match the database environment variables in `docker-compose.yml` too and create the database as mentioned before.
+
+```yml
+environment:
+  - POSTGRES_USER=zed_user
+  - POSTGRES_PASSWORD=zed_password
+  - POSTGRES_DB=zed_database
+#
