# First Welcome from Islamabad this is a demo rust library published on crates.io to use this library you have to add following line in dependency section of cargo.toml `islamabad = "0.1.0"` your cargo.toml file should look like this: ``` [package] name = "hello_world" version = "0.1.0" authors = ["imran82ali "] edition = "2018" [dependencies] islamabad = "0.1.0" ``` In `src/main.rs` you can use like this: ``` use islamabad; fn main() { println!("Hello, world!"); islamabad::welcome(); } ``` following will also work: ``` use islamabad::welcome; fn main() { println!("Hello, world!"); welcome(); } ``` now `cargo run` for results
