+# lNV
+
+lNV is a light-weight .eNV file read/write package.
+lNV isn't very feature-rich compared to dotENV, but for small projects like Discord bots, all you need is a read function, it's wasted space.
+This package also targets to become as easy-to-use as possible!
+
+The documentation will be available soon, at:
+https://lnv.robuxtrex.co.uk
+
+## Early Access
+
+As this is my first package, I would like to clarify that some versions may/will not work. Use at your own risk.
+Though, you can always help me on GitHub issues :D
