 # tina4php-env
 Environment support for your PHP project
+
+An .env will be created for you when the system runs for the first
+time. If you specify an environment variable on your OS called ENVIRONMENT then .env.ENVIRONMENT will be loaded instead.
+
+```bash
+[Section]           <-- Group section
+MY_VAR=Test         <-- Example declaration, no quotes required or escaping, quotes will be treated as part of the variable
+# A commment        <-- This is a comment
+[Another Section]
+VERSION=1.0.0
