 ## Usage
 
+### ED Template
+
+1. **Initialize a new project:**
+   ```bash
+   nix flake init -t github:dwinkler1/np#ed
+   ```
+
+2. **Enter development environment:**
+   ```bash
+   nix develop

+   echo "use flake" > .envrc && direnv allow
+   ```
+
+3. **Start editing:**
+   ```bash
+   vv              # Launch Neovim
+   updateR         # Update R packages (when R is enabled)
+   cowsay "Hello!" # Fun utility included
+   ```
+
+4. **Enable languages:**
+   Edit `flake.nix` and change `false` to `true` in the `cats` section:
+   ```nix
+   cats = {
+     python = true;  # Enable Python support
+     r = true;       # Enable R support
+     julia = true;   # Enable Julia support

-# Project Editor
+# ED Template - Simple Editor Environment
 
-A per-project Neovim wrapper built with [nix-wrapper-modules](https://birdeehub.github.io/nix-wrapper-modules/) and [nvimConfig](https://github.com/dwinkler1/nvimConfig).
+A lightweight, customizable Neovim-based development environment with optional language support for Python, R, Julia, and Nix.
 
-## Setup
+## Features
 
-The flake provides two entry points:
+- ✨ **Lightweight**: Minimal configuration, fast startup
+- 🔧 **Configurable**: Enable only the languages you need
+- 📦 **Reproducible**: Nix-based environment management
+- 🎨 **Themed**: Beautiful Kanagawa colorscheme (customizable)
+- 🔔 **Notifications**: Mini-notify plugin for user feedback
 
-| Command | What you get |
+## Quick Start
-|---|---|
-| `direnv allow` / `nix develop` | **(Recommended)** A shell with `nv` and all enabled language toolchains (R, Python, Julia, Quarto) on `PATH`. |
-| `nix run` | Launches only the `nv` editor. Language toolchains (R, Python, etc.) are **not** on `PATH`. |
-
-### With direnv (recommended)
 
 ```bash
-direnv allow   # enter the devShell automatically
+# Initialize a new project with the ED template
-nv             # launch the pre-configured Neovim
+nix flake init -t github:dwinkler1/np#ed
-R              # R REPL is available (if enabled in flake.nix)
+
+# Enter the development environment
+nix develop
+
+# Launch Neovim
+vv
 ```
 
-### Without direnv
-
-```bash
-nix develop    # enter the devShell manually
-nv             # launch Neovim
-R              # R REPL is available (if enabled in flake.nix)
-```
-
-> **Why `nix run` only gives the editor:** The flake's `packages.default` is the wrapped Neovim binary. Language toolchains (R, radian, quarto, etc.) live in `devShells.default`. Use `nix develop` (or `direnv allow`) to get the full environment.
-
 ## Configuration
 
-The `flake.nix` is the single source of truth. Key knobs:
+The ED template uses a centralized configuration structure at the top of `flake.nix`:
 
-| Option | What it controls |
-|---|---|
-| `cats` | Toggle language support (nix, r, python, julia, etc.) |
-| `settings.lang_packages.<lang>` | Language-specific packages installed in the wrapper |
-| `settings.colorscheme` | Neovim colorscheme |
-| `settings.background` | `"dark"` or `"light"` |
-| `settings.wrapRc` | When `true`, init.lua is embedded (rebuild to change); when `false`, init.lua is external (reload without rebuild) |
-| `binName` | The wrapper binary name (`nv` by default) |
-| `env` | Environment variables set in the wrapper |
-| `extraPackages` | Extra system packages available in the wrapper's PATH |
-| `specs.extraLua` | Inject lazy.nvim plugin specs |
-
-### Adding packages without editing flake.nix
-
-Create any of these optional files in the project root to add dependencies without modifying `flake.nix`:
-
-- **`python-packages.nix`** — receives `python3Packages`, return a list of packages:
 ```nix
-  p: with p; [ numpy scipy ]
+cats = {
+  clickhouse = false;
+  gitPlugins = false;
+  julia = false;
+  lua = false;
+  markdown = false;
+  nix = true;        # Enabled by default
+  optional = false;
+  python = false;
+  r = false;
+};
 ```
 
-- **`r-packages.nix`** — receives `rpkgs` (includes `rPackages`), return a list:
+### Enabling Languages
+
+To enable support for a specific language, edit `flake.nix` and set the corresponding cat to `true`:
+
+#### Python
 ```nix
-  p: with p.rPackages; [ ggplot2 data.table ]
+cats = {
+  python = true;
+  # ... other settings
+};
 ```
 
-- **`julia-packages.nix`** — no arguments, return a list of package name strings:
+Includes: Python 3, duckdb, polars packages by default
+
+#### R
 ```nix
-  [ "DataFrames" "Plots" ]
+cats = {
+  r = true;
+  # ... other settings
+};
 ```
 
-## Formatting
+Includes: fixest package by default
+
+#### Julia
+```nix
+cats = {
+  julia = true;
+  # ... other settings
+};
+```
+
+Includes: StatsBase package by default
+
+### Custom Package Files
+
+You can specify additional packages by creating these files in your project:
+
+- `python-packages.nix` - Additional Python packages
+  ```nix
+  p: with p; [
+    numpy
+    pandas
+    # ... more packages
+  ]
+  ```
+
+- `r-packages.nix` - Additional R packages
+  ```nix
+  p: with p.rPackages; [
+    ggplot2
+    dplyr
+    # ... more packages
+  ]
+  ```
+
+- `julia-packages.nix` - Additional Julia packages
+  ```nix
+  [
+    "DataFrames"
+    "Plots"
+    # ... more packages
+  ]
+  ```
+
+## Available Commands
+
+### Neovim
+- `vv` - Launch Neovim (custom binary name)
+- `vv --headless` - Run Neovim in headless mode for scripting
+
+### Utilities
+- `updateR` - Update R package snapshots from rstats-on-nix
+- `cowsay` - Fun ASCII art text formatter (included as example)
+
+## Customization
+
+### Binary Name
+
+The default binary name is `vv`. To change it, edit the `binName` in `flake.nix`:
+
+```nix
+binName = "myeditor";  # Changes command from 'vv' to 'myeditor'
+```
+
+### Colorscheme
+
+Change the colorscheme in the settings section:
+
+```nix
+settings = {
+  colorscheme = "kanagawa";  # or "gruvbox", "tokyonight", etc.
+  background = "dark";        # or "light"
+  # ...
+};
+```
+
+### Extra Packages
+
+Add more system packages in the `extraPackages` section:
+
+```nix
+extraPackages = with pkgs; [
+  cowsay
+  ripgrep
+  fd
+  # ... more packages
+];
+```
+
+### Welcome Message
+
+The template includes a welcome notification. Customize it in the `specs.extraLua` section:
+
+```nix
+config = ''
+  require("mini.notify").setup()
+  vim.notify = MiniNotify.make_notify()
+  vim.notify("Welcome to ${name}!")
+'';
+```
+
+## Environment Variables
+
+The template sets the following environment variables:
+
+- `IS_PROJECT_EDITOR=1` - Indicates you're in the project editor environment
+- `R_LIBS_USER=./.nvimcom` - Project-local R package directory
+
+## Language Package Management
+
+### Replace vs Merge
+
+By default, language packages are **replaced** rather than merged with base packages. This is controlled by:
+
+```nix
+let
+  replace = pkgs.lib.mkForce;
+in {
+  lang_packages = {
+    python = replace ([...]);  # Replaces base packages
+    r = replace ([...]);       # Replaces base packages
+    julia = replace ([...]);   # Replaces base packages
+  };
+}
+```
+
+To **merge** with base packages instead, remove the `replace` wrapper:
+
+```nix
+lang_packages = {
+  python = (with pkgs.python3Packages; [...]);
+  # ...
+};
+```
+
+## Development Shell
+
+The development shell provides access to the Neovim package plus additional utilities:
 
 ```bash
-nix fmt
+nix develop  # Enter the dev shell
 ```
 
-Uses `nixfmt-rfc-style` pinned via the flake's `formatter` output.
+Available in dev shell:
+- `vv` - The configured Neovim
+- `updateR` - Update R packages (when R support is enabled)
+- All packages listed in `extraPackages`
+
+## Testing
+
+The ED template has comprehensive CI/CD tests:
+
+### Automated Tests (`.github/workflows/check_ed.yml`)
+
+1. **Basic Tests** (Ubuntu)
+   - Build verification
+   - Flake check
+   - Dev shell entry
+   - Neovim launch and version check
+   - Utility commands availability
+
+2. **Language-Specific Tests**
+   - Python configuration: Package imports, code execution
+   - R configuration: Package loading, code execution
+   - Julia configuration: Version check, code execution
+   - Multi-language: All languages enabled together
+
+3. **macOS Tests** (`.github/workflows/check_macos.yml`)
+   - Build verification on macOS
+   - Basic functionality tests
+
+## Tips
+
+1. **Use direnv for automatic environment loading:**
+   ```bash
+   echo "use flake" > .envrc
+   direnv allow
+   ```
+
+2. **Pin specific package versions** by editing `flake.lock`:
+   ```bash
+   nix flake update  # Update all inputs
+   nix flake lock --update-input nixpkgs  # Update specific input
+   ```
+
+3. **Check what's included in your build:**
+   ```bash
+   nix path-info -Sh ./result
+   ```
+
+4. **Build for different platforms:**
+   ```bash
+   nix build .#packages.x86_64-linux.default
+   nix build .#packages.aarch64-darwin.default
+   ```
+
+## Comparison with RDE Template
+
+| Feature | ED Template | RDE Template |
+|---------|-------------|--------------|
+| **Complexity** | Lightweight | Comprehensive |
+| **Binary Name** | `vv` | `p` |
+| **Project Structure** | Manual | `p-initProject` command |
+| **Language Support** | Optional (Python, R, Julia, Nix) | Built-in (R default, Python/Julia optional) |
+| **Research Tools** | None | Quarto, Marimo, Pluto.jl |
+| **Package Management** | updateR | p-updateDeps (comprehensive) |
+| **Use Case** | Simple editing, lightweight projects | Research, data science, complex projects |
+
