+# Groups
+
+Groups are curated sets of packages exposed as flake outputs. Each group has two forms:
+
+- **`homeManagerModules.<group>`** — full home-manager module (packages + files + systemd units)
+- **`packages.<group>`** — standalone environment for `nix shell` (packages only)
+
+## Available groups
+
+- dev (go, bun, air, ...)
+- cybersecurity (nmap, john, dirb, ffuf, ...)
+
+For the Cybersecurity group, the home-manager module also sets up:
+
+- `~/Cyber/wordlists/` with SecLists, fuzz4bounty, and hashcat rules
+- `~/Cyber/tmp/` as a temporary workspace
+
+## Use in another flake
+
+Add this repo as an input:
+
+```nix
+inputs.nixy.url = "github:anotherhadi/nixy";
+```
+
+Import the home-manager module in your home configuration:
+
+```nix
+{ inputs, ... }: {
+  imports = [
+    inputs.nixy.homeManagerModules.cybersecurity
+    # inputs.nixy.homeManagerModules.dev
+  ];
+}
+```
+
+## Quick shell without installing
+
+```sh
+nix shell github:anotherhadi/nixy#cybersecurity
+nix shell github:anotherhadi/nixy#dev
+```
+
+This drops you into a shell with all tools in `PATH`. No home-manager required, no wordlists or systemd units.

+# Neovim
+
+The Neovim configuration is built with [nvf](https://github.com/notashelf/nvf) and exposed as a standalone flake output.
+It can be used in three ways: run it directly, import it into another flake's home-manager setup, or use it as part of this config.
+
+## Run directly
+
+No installation needed:
+
+```sh
+nix run github:anotherhadi/nixy#nvim
+```
+
+## Use in another flake
+
+Add this repo as an input:
+
+```nix
+inputs.nixy.url = "github:anotherhadi/nixy";
+```
+
+Then import the home-manager module in your home configuration:
+
+```nix
+{ inputs, ... }: {
+  imports = [
+    inputs.nixy.inputs.nvf.homeManagerModules.default
+    inputs.nixy.homeManagerModules.nvim
+  ];
+}
+```
+
+> [!NOTE]
+> The `nvf` home-manager module is required. It is re-exported via `inputs.nixy.inputs.nvf` so you don't need to declare it separately in your own flake.
+
+## What's included
+
+| File            | Description                                                            |

+| `languages.nix` | LSP, treesitter, formatters, diagnostics, and per-language config      |
+| `keymaps.nix`   | All key mappings (leader: `space`)                                     |
+| `picker.nix`    | Snacks picker + oil.nvim                                               |
+| `snacks.nix`    | Snacks extras: image preview, zen mode, git signs, statuscolumn        |
+| `utils.nix`     | Bufferline, lualine, copilot, lazygit, toggleterm, autocomplete        |
+| `mini.nix`      | Mini.nvim suite: pairs, comment, icons, indentscope, diff, git         |
