-# Forge - A Home-Manager Like Tool for Fedora
+# curator - A Home-Manager Like Tool for Universal Blue builds
 
-A lightweight configuration management tool for Fedora that provides COPR repository management, dotfile management and package installation functionality through a centralized TOML configuration.
+A lightweight CLI that provides repository and dotfile management and package installation functionality through a centralized TOML configuration. Ported and expanded from [forge](https://github.com/ijadux2/forge) and inspired by [home-manager](https://github.com/nix-community/home-manager/).
 
 ## Overview
 
-Forge is a bash script that helps you manage your Fedora system configuration by:
+curator is a Python CLI that helps you manage your Fedora system configuration by:
 - Managing COPR repositories (enable/disable automatically)
-- Installing and managing system packages via dnf
+- Installing and managing system packages via `dnf` or `rpm-ostree`
+- Installing and managing userspace packages via `brew`, `flatpak`, or `nix`
 - Managing dotfiles through symlinks to actual files
-- Centralized configuration via a single `forge.toml` file
-- User-level configuration similar to home-manager/nixos
+- Centralized configuration via a single `inventory.toml` file
+- Declarative user-level configuration similar to `home-manager`/`nixos`
 - Automatic backup of existing files before replacement
 
 ## Installation
 
-1. Clone or download this repository
-2. Make the script executable:
+Install the CLI directly from GitHub with [uv](https://github.com/astral-sh/uv): 
+
 ```bash
-   chmod +x forge
-   ```
-3. Optionally, move it to a directory in your PATH:
-   ```bash
-   sudo mv forge /usr/local/bin/forge
+uv tool install --from git+https://codeberg.org/randogoth/curator/ curator
 ```
 
 ## Quick Start
 
 ```bash
 # Initialize the configuration structure
-./forge init
+curator init
 
 # Edit the configuration file to add packages and dotfiles
-nano ~/.config/forge/forge.toml
+nano ~/.config/curator/inventory.toml
 
 # Apply configuration
-./forge switch
+curator switch
 
 # Check status
-./forge status

+Initialize the configuration structure and create `inventory.toml`.
 
 ```bash
-./forge init

 ```bash
-./forge switch
+curator switch
+# or ./curator switch
+# rollback to the previous inventory.toml and apply it
+curator switch --rollback
 ```
 
 This command:
-1. Enables all COPR repositories listed in `forge.toml`
+1. Enables all COPR repositories listed in `inventory.toml`
 2. Disables COPR repositories that are no longer configured
-3. Installs all packages listed in `forge.toml`
+3. Installs all packages listed in `inventory.toml`
 4. Creates symlinks for all configured dotfiles
-5. Creates backups of existing files before replacing them
-6. Updates the last switch timestamp
+5. Applies environment variables to `~/.config/environment.d/20-curator.conf` and imports them into the user session
+6. Creates backups of existing files before replacing them
+7. Updates the last switch timestamp
 
 ### `status`
 Show current configuration status and information.
 
 ```bash
-./forge status

 Show help message with all available commands.
 
 ```bash

 ```
 
+### `from`
+Import currently installed packages/repos for a manager into `inventory.toml` so curator can manage them.
+
+```bash
+curator from dnf
+curator from brew
+curator from flatpak
+curator from rpm-ostree
+curator from nix
+curator from copr
+```
+
+### `add` / `remove`
+Add or remove entries directly in `inventory.toml` using `section:value` pairs. Supports `dnf`, `brew`, `flatpak`, `rpm-ostree`, `nix`, and `copr`.
+
+```bash
+curator add dnf:uv nix:micro
+curator remove dnf:curl flatpak:org.mozilla.firefox
+```
+
+### `reset`
+Remove the rollback snapshot (`inventory.toml.rollback`).
+
+```bash
+curator reset
+```
+
+### `env`
+Apply environment variables defined in `[variables]` and propagate them to systemd/DBus. For your current shell, run:
+
+```bash
+curator env
+# then, to update this shell:
+eval "$(curator env --eval-only)"
+```
+
+Use `curator env --eval-only` in shell init files if you want each shell to export the current `[variables]` values without touching `environment.d` or systemd/DBus.

-## How It Works
-
-### COPR Repository Management
-COPR repositories are managed through the `[copr]` section in `forge.toml`:
-- **Add COPR repo**: Simply add the repository name on a new line
-- **Remove COPR repo**: Delete the line containing the repository name
-- **Automatic cleanup**: Forge automatically disables COPR repos that are removed from configuration
-- **No flags needed**: Just presence/absence of the repository name matters
-
-### Package Management
-Packages are managed through the `[packages]` section in `forge.toml`:
-- **Add package**: Simply add the package name on a new line
-- **Remove package**: Delete the line containing the package name
-- **No flags needed**: Just presence/absence of the package name matters
-
-### Dotfile Management
-Forge uses symlinks to manage dotfiles:
-1. Your actual dotfiles are stored in `~/.config/forge/dotfiles/`
-2. Symlinks are created from your home directory to these files
-3. This allows you to version control your dotfiles in one place
-4. Changes to the source files are immediately reflected in your home directory
-
-### Backup System
-Before creating symlinks, Forge:
-1. Checks if the target file exists and is not a symlink
-2. Creates a timestamped backup in the backup directory
-3. Removes the original file
-4. Creates the symlink to your managed dotfile
-
-## Examples
-
-### Basic Setup
-```bash
-# Initialize forge
-./forge init
-
-# Edit forge.toml to add COPR repos and packages
-nano ~/.config/forge/forge.toml
-
-# Add to [copr] section:
-copr.fedorainfracloud.org/username/cool-repo
-
-# Add to [packages] section:
-git
-vim
-curl
-
-# Create your dotfiles directory and add files
-mkdir -p ~/.config/forge/dotfiles
-echo "export EDITOR=vim" > ~/.config/forge/dotfiles/.bashrc
-
-# Add to [dotfiles] section:
-".bashrc" = "dotfiles/.bashrc"
-
-# Apply configuration
-./forge switch
-```
-
-### Managing Application Configurations
-```bash
-# Add alacritty configuration
-mkdir -p ~/.config/forge/dotfiles/.config/alacritty
-cp ~/.config/alacritty/alacritty.yml ~/.config/forge/dotfiles/.config/alacritty/
-
-# Edit forge.toml
-nano ~/.config/forge/forge.toml
-
-# Add to [dotfiles] section:
-".config/alacritty/alacritty.yml" = "dotfiles/.config/alacritty/alacritty.yml"
-
-# Apply changes
-./forge switch
-```
-
-### COPR Repository Management Examples
-```toml
-[copr]
-# Development tools COPR
-copr.fedorainfracloud.org/development/tools
-copr.fedorainfracloud.org/user/neovim-nightly
-
-# To remove a COPR repo, just delete the line
-# Forge will automatically disable it during the next switch
-```
-
-### Package Management Examples
-```toml
-[packages]
-# Development tools
-git
-vim
-nodejs
-npm
-
-# System utilities
-curl
-wget
-tree
-htop
-
-# To remove a package, just delete the line
-# For example, to remove htop, delete the "htop" line
-```
-
-### Version Control Your Configuration
-```bash
-# Initialize git repository in forge directory
-cd ~/.config/forge
-git init
-git add .
-git commit -m "Initial configuration"
-
-# Now you can version control your entire system configuration
-git add forge.toml dotfiles/
-git commit -m "Updated vim configuration"
-```
-
 ## Environment Variables
 
-- `FORGE_DIR`: Override the default configuration directory (default: `~/.config/forge`)
-
-## Dependencies
-
-- `dnf` - Fedora package manager
-- `dnf-plugins-core` - For COPR repository management
-- `sed` - For updating configuration file (usually pre-installed)
-
-## Migration from Previous Version
-
-If you were using the old version of forge with `git = true` format:
-
-1. Your existing configuration will not be automatically migrated
-2. Run `./forge init` to create the new `forge.toml` structure
-3. Convert your package configuration from:
-   ```toml
-   # Old format
-   git = true
-   vim = true
-   ```
-   to:
-   ```toml
-   # New format
-   git
-   vim
-   ```
-4. Move your existing dotfiles from the old directory to `~/.config/forge/dotfiles/`

- FILES:
-      $FORGE_DIR/              Main configuration directory
-      $FORGE_TOML              Configuration file for COPR, packages and dotfiles
-
- EXAMPLES:
-      forge init
-      # Edit $FORGE_TOML to add COPR repos, packages and dotfiles
-      forge switch
-      forge status
