 This repository is a work in progress, and still in early development.
 
 ## Installation
+
 To install `gtars`, you must have the rust toolchain installed. You can install it by following the instructions [here](https://www.rust-lang.org/tools/install).
 
 You may build the binary locally using `cargo build --release`. This will create a binary in `target/release/gtars`. You can then add this to your path, or run it directly.
 
 ## Usage
+
 `gtars` is very early in development, and as such, it does not have a lot of functionality yet. However, it does have a few useful tools. To see the available tools, run `gtars --help`. To see the help for a specific tool, run `gtars <tool> --help`.
 
 Alternatively, you can link `gtars` as a library in your rust project. To do so, add the following to your `Cargo.toml` file:
+
 ```toml
 [dependencies]
 gtars = { git = "https://github.com/databio/gtars" }
 ```
 
 ## Testing
+
 To run the tests, run `cargo test`.
 
 ## Contributing
+
 ### New internal library crate tools
+
 If you'd like to add a new tool, you can do so by creating a new module within the src folder.
 
 ### New public library crate tools
+
 If you want this to be available to users of `gtars`, you can add it to the `gtars` library crate as well. To do so, add the following to `src/lib.rs`:
 ```rust
 pub mod <tool_name>;
 ```
 
 ### New binary crate tools
+
 Finally, if you want to have command-line functionality, you can add it to the `gtars` binary crate. This requires two steps:
+
 1. Create a new `cli` using `clap` inside the `interfaces` module of `src/cli.rs`:
+
 ```rust
 pub fn make_new_tool_cli() -> Command {
 
 }
 ```
 
 2. Write your logic in a wrapper function. This will live inside the `functions` module of `src/cli.rs`:
+
 ```rust
 // top of file:
 use tool_name::{ ... }

 Please make sure you update the changelog and bump the version number in `Cargo.toml` when you add a new tool.
 
 ### VSCode users
+
 If you are using VSCode, make sure you link to the `Cargo.toml` inside the `.vscode` folder, so that `rust-analyzer` can link it all together:
