 ### Installation  
-Download a binary for your platform, and place it in your PATH.  
+Download a binary for your platform, and place it in your `$PATH`.  
 Currently, only Windows (x86_64, gnu/msvc) and Linux (x86_64/aarch64, gnu/musl) have binaries available. If you want a binary for another platform, you will have to follow the instructions to build from source.
 
 ### Dependencies 
 #### Build/Install
-To build Oxidefetch, you need Cargo. You can use Cargo to automatically build and install it like so:
-`cargo install --git https://github.com/shibedrill/oxidefetch`. (Alternatively, you can get it from the Crates repos, using `cargo install oxidefetch`. But it might be slightly out of date.) From there, it *should* be in your `$PATH`. If not, add `source ~/.cargo/env` to your profile, or add `~/.cargo/bin` to your `$PATH`. If you do not already have Cargo installed on your system, you can do so by installing Rustup- either via the [instructions on their website](https://doc.rust-lang.org/cargo/getting-started/installation.html "instructions on their website") or via your system package manager. You will also probably need a C compiler and a build system- most likely CMake or GNU Make. You will be prompted to install these if they're not found during compilation.

 ### How you can help with the project
-I need to verify the output of the OS information detection libraries I'm pulling in. To do this, I need the help of people with varying types of systems. I've tested a few, but there's some I'm unable to test. To help, you can kindly clone this repo, and inside the folder, run `cargo test -- --nocapture`, and send the resultant `test_output.txt` file to my noreply email address, or directly to me on Discord at `@shibedrill`. This program does NOT collect information regarding your real name, IP, location, hardware serial numbers, etc. You can look at the file it generates to be sure- it's all plaintext, babey.
