 This project is published on [crates.io](https://crates.io/crates/httpget), and can be installed using `cargo` with the command `cargo install httpget`. This will **not** produce a statically-linked binary: for that, you must ensure that you've installed the correct `*-unknown-linux-musl` target.
 
 You can also clone this repository and run `cargo install --path .` to install through Cargo

+There are two supported ways to pass an endpoint to `httpget`. The first is to pass it explicitly (e.g. `httpget http://example.com/`). The second is to specify the endpoint in the `HTTPGET_ENDPOINT` environment variable, and call `httpget` with no arguments.
