 # dotenv: readEnvFile()
 
-A single function implementation of <https://github.com/vlucas/phpdotenv>
+A simple implementation of <https://github.com/vlucas/phpdotenv>
 
 This is not a functional replacement, but a very simple implementation of the basic functions.
 
 It is recommended to create a `.env.example` example file that is checked into the
 repository. The `.env` should *NEVER* be checked into anything
 
+## How to install
+
+`comoser require gullevek/dotEnv`
+
 ## How it works
 
 Put the function where it is needed or put it in a file and load it.
