+## Usage Examples
+
+Here are some basic examples of how to use the library:
+
+```rust
+use ark_ff::Field;
+use ark_ec::Group;
+
+// Example 1: Working with finite fields
+use ark_test_curves::bls12_381::Fr;
+let a = Fr::from(2u64);
+let b = Fr::from(3u64);
+let c = a + b; // Field addition
+
+// Example 2: Working with elliptic curves
+use ark_test_curves::BLS12_381;
+let generator = BLS12_381::generator();
+let point = generator.double(); // Point doubling
+```
+
+For more examples, please check the `tests` directory in each crate.

+## Build Guide
 
 The library compiles on the `stable` toolchain of the Rust compiler (v 1.51+). To install the latest version of Rust, first install `rustup` by following the instructions [here](https://rustup.rs/), or via your platform's package manager. Once `rustup` is installed, install the Rust toolchain by invoking:

 Note that because inline assembly support in Rust is currently unstable, using this backend requires using the Nightly compiler at the moment.
