+# Module 1: Beginner
+
+<br>
+
+
+### Rust is an ahead-of-time compiled language
+
+* The `main` function in Rust is always the first code that runs in every executable Rust program.
+
+* In any directory, compile and run a Rust program with:
+
+
+```sh
+rustc main.rs
+./main
+```
+
+
+<br>
+
+---
+
+### Cargo
+
+* Cargo is a dependency manager and build tool, which makes adding, compiling, and managing dependencies painless and consistent across the Rust ecosystem.
+
+* A crate is a collection of Rust source code files. Cargo coordinates external crates in the `Cargo.toml` file. You can add a new crate with `cargo add <crate name>` and update with `cargo update <crate name>`.
+
+
+#### Creating a new project
+
+```sh
+cargo new gm_world
+```
+
+* This command creates a cargo TOML file and a placeholder for `main.rs`:
+
+```sh
+.
+├── Cargo.toml
+└── src
+    └── main.rs
+```
+
+
+#### Building and running with Cargo
+
+* Alternatively, in any directory, compile and run a Rust program with:
+
+
+```sh
+cargo build
+```
+
+* This command creates a file named `Cargo.lock` (which keeps track of the versions for all dependencies), and an executable inside `target/debug/` that can be ran. 
+
+* If you are building for release or benchmarking, add the flag `--release` to compile it with optimizations (and the target will be `release`).
+
+* Additionally, you can build and run with:
+
+```sh
+cargo run
+```
+
+* Finally, to make sure your code compile in a fast manner without executing it, you can run:
+
+```sh
+cargo check
+```
+
+
+
+<br>
+
+---
+
+### Rustfmt
+
+* A formatting tool ensuring a consistent coding style across developers.
+
+<br>
+
+---
+
+### Macros
+
+* A `!` (as in `println!`) calls a Rust macro.
+
+<br>
+
+---
+
+### Variables
+
+* Variables and references are immutable by default.
+* Constants are declared with `const` and always immutable.
+
+<br>
+
+----
+
+### Results
+
+* Rust handles potential failure with `Result`, which is an `enumeration` (`enum`, a type that can be in one of multiple possible states or variant).
