# Getting started
## Intro
To start, open Quickstart page [localhost:8020](http://localhost:8020/) for quick access to all the tools
From the quicklaunch page you can open workspace tools, such as code editor or terminal
Demo: Workspace UI
The main code editor of this workspace is [Code-server](https://github.com/cdr/code-server)
Demo: Code-server
Workspace has full-size browser-base terminal
## Hello world
Check Rust version
```
rustc --version
```
Create new project folder
```
cargo new my_example
cd my_example
```
The new project is created together, with hello-world app in `src` sub-folder
```
cat src/main.rs
```
Compile it
```
cargo build
```
And then run it
```
./target/debug/my_example
```
We can also compile and then run it, all in one step
```
cargo run
```
## Rustup
A toolchain is a specific version of the collection of programs needed to compile a Rust application. It includes, but is not limited to:
- The compiler, rustc
- The dependency manager and build tool, cargo
- The documentation generator, rustdoc
Rustup provides ways to install, remove, update, select and otherwise manage these toolchains and their associated pieces.
Install specific version of Rust toolchain
```
rustup install 1.30.0
```
Show toolchains
```
rustup show
```
Change default toolchain
```
rustup default 1.30.0
```
## Project with dependencies
Cargo is also the Rust package manager. It is a tool that allows Rust packages to declare their various dependencies and ensure that you’ll always get a repeatable build.
Clone example repo
```
git clone https://github.com/rdesarz/rust-http-server.git
cd rust-http-server
```
Build and start the server
```
cd example
cargo run --package http-server --bin http-server 0.0.0.0:8030
```
You will see that before cargo builds the package, it installs all the dependencies from the file `Cargo.toml`.
Open in your browser [0.0.0.0:8030/hello.html](http://0.0.0.0:8030/hello.html) to see a simple page.
