+### Environment Variables
+
+ConfigLib can be interacted with using environment variables with two functions
+
+ - Import a YAML file
+ - Override configuration values
+
+#### Importing a YAML file
+
+You can tell ConfigLib to load a YAML file by setting the `CONFIGLIB_<CONFIG_NAME>` environment variable with the path
+to the YAML file as the value, for example:
+
+```bash
+export CONFIGLIB_MYCONFIG=/path/to/myconfig.yaml
+```
+
+#### Overriding configuration values
+
+If loading an entire YAML file is too much, you can override specific configuration values by setting the environment
+variable `CONFIGLIB_<CONFIG_NAME>_<PROPERTY_NAME>` with the value you want to set, for example:
+
+```bash
+export CONFIGLIB_MYCONFIG_DATABASE_USERNAME=root
+```
+
+This would override the `database.username` property in the `myconfig` configuration file even if the property is
+already set, the environment variable will take precedence.
