# ❄️ My NixOS Configuration
This directory contains the declarative configuration for my user environment, managed by **Home Manager**.
## 🛠️ How it Works (The Nix Way)
In NixOS, configuration files are managed "declaratively" rather than manually.
1. **The Source of Truth**: Everything is defined in your `.nix` files.
2. **The Nix Store**: When you "switch," Nix builds your files and stores them in `/nix/store/`. These are **immutable** (read-only).
3. **Symlinking**: Home Manager creates symbolic links in your home directory (like `~/.pi/agents/settings.json`) that point back to that read-only store.
## ✍️ How to Make Changes
**Do not edit the files in your home directory.** They are read-only symlinks. To change settings:
1. **Edit your source code**: Open `home.nix` in `nvim`.
2. **Modify the Nix block**: Locate the `home.file` section for your agents.
3. **Apply changes**:
```bash
home-manager switch
```
## ❓ Why "sudo" doesn't work
The `/nix/store` is mounted as read-only at the system level. This ensures your system always matches your config and allows for instant **rollbacks** if something breaks.
