+## Basic usage
+
+Include this [library](https://crates.io/crates/gp2y0e02b) as a dependency in your `Cargo.toml`:
+
+```rust
+[dependencies.gp2y0e02b]
+version = "<version>"
+```
+
+Use [embedded-hal](https://github.com/rust-embedded/embedded-hal) implementation to get I2C handle and then create gp2y0e02b handle.
+
+```rust
+extern crate gp2y0e02b;
+```
