+![GitHub Workflow Status](https://img.shields.io/github/actions/workflow/status/nekowinston/dotfiles/check.yml?label=flake%20check&logo=nixos&logoColor=%23fff&style=flat-square)
+
+Welcome to my cross-platform dots. Focused on improving productivity, and reducing the pain of switching between operating systems. Minimal rice, with a focus on getting the annoying stuff out of the way.
+
+> **Note**
+> I've recently switched to **[Nix](https://nixos.org)** & **[Home-Manager](https://github.com/nix-community/home-manager)** for my dotfile management.\
+> Since the chezmoi version of my dots was somewhat popular, I have [tagged them](https://github.com/nekowinston/dotfiles/tree/chezmoi) if you want to use them for reference.
+
+### Overview
+
+Here's what you can find:
+
+- **[WezTerm](https://wezfurlong.org/wezterm/)** as my terminal, with tmux-like keybindings
+- **[Neovim](https://neovim.io)** as my tui editor & my JetBrains IdeaVim config
+- **[Neomutt](http://www.neomutt.org)** as my mail client
+- **[Taskwarrior](https://taskwarrior.org)** for task management
+- **[Starship](https://starship.rs)** as my prompt
+- **Firefox** with privacy-centered settings
+- My **PGP** & **[Sops.nix](https://github.com/Mic92/sops-nix)** settings
+- Other random bits of config tools I've collected over the years
+- The **[Catppuccin](https://github.com/catppuccin)** theme, wherever possible
+- macOS:
+  - **[Yabai](https://github.com/koekeishiya/yabai)** as my wm
+- Linux:
+  - **[i3](https://i3wm.org)** as my wm
+
+### Todos from my previous chezmoi setup:
+
+These are things I used to have with chezmoi, but are currently missing in this config:
+
+- **[bugwarrior](https://github.com/ralphbean/bugwarrior)** for ticket integration
+- **[taskwiki](https://github.com/tools-life/taskwiki)** for task management in neovim
