 # Custom environment

-This repository contains the settings of my environment for development and everyday tasks.
-## Configs
-- `nvim`
-- `kitty`
-- `starship`
-- `hyperland` & `hyperpaper` & `hyperlock`
-- `waybar`
+
+My personal development environment and dotfiles. The repository contains the
+configuration I use to keep the terminal, editor, shell history, and Git
+workflow consistent across machines.
+
+## Toolset
+
+| Tool | Purpose |
+| --- | --- |
+| [Kitty](https://sw.kovidgoyal.net/kitty/) | Terminal emulator |
+| [Neovim](https://neovim.io/) | Editor and development environment |
+| [Starship](https://starship.rs/) | Fast, minimal shell prompt |
+| [direnv](https://direnv.net/) | Per-project environment variables |
+| [zoxide](https://github.com/ajeetdsouza/zoxide) | Smarter directory navigation |
+| [Atuin](https://atuin.sh/) | Searchable shell history |
+| [fzf](https://github.com/junegunn/fzf) | Fuzzy finding from the command line |
+| [eza](https://github.com/eza-community/eza) | Modern replacement for `ls` |
+| [GitUI](https://github.com/gitui-org/gitui) | Terminal UI for Git |
+
+The shell configuration also includes shortcuts for Meson and Ninja builds,
+sanitizer-assisted test runs, `perf`, FlameGraph, and systemd user scopes.
+
+## Repository layout

+├── .bashrc               # Bash environment, aliases, and helper functions
+├── atuin/                # Atuin configuration
+├── gitui/                # GitUI key bindings

+```
+
+Starship, direnv, zoxide, fzf, and eza do not currently have dedicated
+configuration directories tracked in this repository.
+
+## Installation
+
+Clone the repository, install the tools listed above using your system package
+manager, and link the configuration files into their expected locations. For
+example:
+
+```bash
+git clone git@github.com:Claucdan/Custom-environment.git
+cd Custom-environment
+
+ln -sfn "$PWD/nvim" "$HOME/.config/nvim"
+ln -sfn "$PWD/kitty" "$HOME/.config/kitty"
+ln -sfn "$PWD/atuin" "$HOME/.config/atuin"
+ln -sfn "$PWD/gitui" "$HOME/.config/gitui"
+```
+
+Review `.bashrc` before sourcing or linking it: some aliases, paths, and helper
+functions are tailored to my local development setup.
+
+## Notes
+
+- A [Nerd Font](https://www.nerdfonts.com/) is recommended for Kitty,
+  Starship, and terminal icons.
+- Neovim plugins are managed with
+  [lazy.nvim](https://github.com/folke/lazy.nvim); open Neovim after linking the
+  configuration to install them.
+- This is a personal setup rather than a universal bootstrap script. Feel free
+  to copy or adapt any part of it.
