+In the main directory, create a virtual env
+
+```

+```
+
+to activate it :
+
+```
+source .env/bin/activate
+```
+
+
+### Env variables inside the .env file
+
+Edit .env/bin/activate
+
+In the deactivate () function, append at the end:
+```
+    # unset required variables
+    unset DB_HOST
+    unset DB_PORT
+    unset DB_USERNAME
+    unset DB_PASSWORD
+    unset DB_DATABASE
+    unset ALLOWED_HOSTS
+    unset DEBUG
+```
+
+at the end of the file add the DB value for testing:
+
+```
+    export DB_HOST=localhost
+    export DB_PORT=5432
+    export DB_USERNAME=postgres
+    export DB_PASSWORD=example
+    export DB_DATABASE=cloudmanager
+    export CUSTOM_DB_DATABASE=cloudmanager
+    export ALLOWED_HOSTS="0.0.0.0,localhost,127.0.0.1"
