 While this tool might seem limited in scope and purpose, that is by design.
 
 By default, `gfold` looks at every Git repository via traversal from the current working directory.
-However, if you would like to target another directory, you can pass that path (relative or absolute) as the first argument or change the default path in the config file.
+If you would like to target another directory, you can pass its path (relative or absolute) as the first argument or change the default path in the config file.
 
-## Installation
+After traversal, `gfold` leverages [rayon](https://github.com/rayon-rs/rayon) to perform concurrent, read-only analysis of all Git repositories detected.
+Analysis is performed with the `git` CLI rather than [libgit2](https://github.com/rust-lang/git2-rs) to reduce binary size.
 
-[![Packaging status](https://repology.org/badge/vertical-allrepos/gfold.svg)](https://repology.org/project/gfold/versions)
+## Usage
 
-**macOS users:** you can use [Homebrew](https://brew.sh) to install the [tap](https://github.com/nickgerace/homebrew-nickgerace/blob/main/Formula/gfold.rb).
+Pass in `--help` flag to see all the options for using this application.
 
 ```bash
-brew install nickgerace/nickgerace/gfold
+gfold
+gfold ..
+gfold $HOME
+gfold ~/
+gfold /this/is/an/absolute/path
+gfold ../../this/is/a/relative/path
 ```
 
-_Note:_ the tap may not work with [Linuxbrew](https://docs.brew.sh/Homebrew-on-Linux).
+### Config File
 
-**Arch Linux users:** you can use [pacman](https://wiki.archlinux.org/title/Pacman) to install `gfold` from the [community repository](https://archlinux.org/packages/community/x86_64/gfold/):
+Upon execution, `gfold` will look for a config file at the following path on macOS, Linux and similar operating systems:
 
 ```bash
-pacman -S gfold
+$HOME/.config/gfold/gfold.json
 ```
 
-[Development (VCS) package](https://aur.archlinux.org/packages/gfold-git/) can be installed from the AUR:
+On Windows, the config file is located at the following path:
 
-```bash
-paru -S gfold-git
+```powershell
+{FOLDERID_Profile}\.config\gfold\gfold.json
 ```
 
-_Note:_ the above example uses [paru](https://github.com/Morganamilo/paru), which is an [AUR helper](https://wiki.archlinux.org/index.php/AUR_helpers) used to install packages from the AUR.
+Creating and using the config file is entirely optional, and you can ignore your config file at any time using the `-i` flag.
 
-**Rust developers and Cargo users:** you can use [cargo](https://crates.io) to install the [crate](https://crates.io/crates/gfold) on almost any platform.
+Here is an example creation workflow for a config file:
 
 ```bash
-cargo install gfold
+gfold --classic ~/ --print > $HOME/.config/gfold/gfold.json
 ```
 
-Keeping the crate up to date is easy with [cargo-update](https://crates.io/crates/cargo-update).
+This config file will default to the classic display mode and set the default path to `$HOME`, rather than the current working directory.
 
-```bash
-cargo install cargo-update
-cargo install-update -a
+Here are the contents of the resulting config file:
+
+```json
+{
+  "path": "/home/neloth",
+  "display_mode": "Classic",
+  "git_path": null
+}
 ```
 
-**Install from source:** if you want to install from source, and not from [crates.io](https://crates.io/crates/gfold), you can clone the repository and build `gfold`.
+You can back up a config file and track its history with `git`.
+On macOS, Linux, and most systems, you can link the file back to a `git` repository.
 
 ```bash
-git clone https://github.com/nickgerace/gfold.git
-cd gfold
-make install
+ln -s path/to/repository/gfold.json $HOME/.config/gfold/gfold.json
 ```
 
-**Download a binary:** if you do not want to use one of the above installation methods, you can download a binary from the [releases](https://github.com/nickgerace/gfold/releases) page.
+Now, you can update the config file within your repository and include the linking as part of your environment setup workflow.
 
-```bash
-curl -s https://raw.githubusercontent.com/nickgerace/gfold/main/scripts/install.sh | bash
-```
+## Installation
 
-_Note:_ the installation convenience script _does not verify the binary with a checksum_.
-Discretion is advised, including downloading and reading the script before execution.
+[![Packaging status](https://repology.org/badge/vertical-allrepos/gfold.svg)](https://repology.org/project/gfold/versions)
 
-To uninstall `gfold` fully, after using this installation method, execute the following script:
+**macOS users:** you can use [Homebrew](https://brew.sh) to install the [tap](https://github.com/nickgerace/homebrew-nickgerace/blob/main/Formula/gfold.rb).
 
 ```bash
-curl -s https://raw.githubusercontent.com/nickgerace/gfold/main/scripts/uninstall.sh | bash
+brew install nickgerace/nickgerace/gfold
 ```
 
-The uninstall script can also be used for cleanup in the event of a failed install.
+_Note:_ the tap may not work with [Linuxbrew](https://docs.brew.sh/Homebrew-on-Linux).
