## 1. Overview
Welcome to the Leo programming language.
Leo provides a high-level language that abstracts low-level cryptographic concepts and makes it easy to
integrate private applications into your stack. Leo compiles to circuits making zero-knowledge proofs practical.
The syntax of Leo is influenced by traditional programming languages like JavaScript, Scala, and Rust, with a strong emphasis on readability and ease-of-use.
Leo offers developers with tools to sanity check circuits including unit tests, integration tests, and console functions.
Leo is one part of a greater ecosystem for building private applications on [Aleo](https://aleo.org/).
The language is currently in an alpha stage and is subject to breaking changes.
## 2. Build Guide
### 2.1 Install Rust
We recommend installing Rust using [rustup](https://www.rustup.rs/). You can install `rustup` as follows:
- macOS or Linux:
```bash
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
```
- Windows (64-bit):
Download the [Windows 64-bit executable](https://win.rustup.rs/x86_64) and follow the on-screen instructions.
- Windows (32-bit):
Download the [Windows 32-bit executable](https://win.rustup.rs/i686) and follow the on-screen instructions.
### 2.2 Build from Source Code
We recommend installing Leo by building from the source code as follows:
```bash
# Download the source code
git clone https://github.com/AleoHQ/leo
cd leo
# Install 'leo'
$ cargo install --path .
```
Now to use leo, in your terminal, run:
```bash
leo
```
## 3. Quick Start
Use the Leo CLI to create a new project
```bash
# create a new `hello-world` Leo project
leo new helloworld
cd helloworld
# build & setup & prove & verify
leo run
```
The `leo new` command creates a new Leo project with a given name.
The `leo run` command will compile the program into Aleo instructions and run it.
Congratulations! You've just run your first Leo program.
