+###  Example .env file
+###  Real .env should not be shared, never pushed to git, etc.
+###
+###  Make a copy and modify at need (e.g. .dev.env)
+###  Symlink the copy to the .env using the bash command :
+###  ln -s .dev.env .env
+###
+###  As long as the symlink is active, modifications in .dev.env
+###  will be reported in .env, thus updating the app global env
