 **fhEVM-go** is an open-source library used to easily integrate the [fhEVM](https://docs.zama.ai/fhevm) into an EVM-compatible blockchain.
 
-
 ## Main features
 
 fhEVM-go gives your EVM the ability to compute on encrypted data using fully homomorphic encryption by:
+
 - a collection of operations on encrypted data via precompiled contracts
 - various additional EVM components that support encrypted computation
 
-
 ## Getting started
 
 In order to use the library, you need to clone the repository and build it. This is required because the library depends on the `tfhe-rs` library that needs to be built from source (for now), and Go doesn't support such a build.
+
 ```bash
 $ git clone https://github.com/zama-ai/fhevm-go
 $ cd fhevm-go
 $ make build
 ```
 
 That's it! You can now use it in your project by adding it to `go.mod`, and adding a `replace` to point to your local build. An example using `fhevm-go` v1.0.0:
