 **NEVER run git commands.** This repo uses Jujutsu (`jj`). Use `jj status`, `jj diff`, `jj commit`, etc.
 
 ## Build Commands
+
+### Local Development
 ```bash
 nix run .#build               # Build current host config
 nix run .#build -- <hostname> # Build specific host (chidi, jason, michael, mindy, tahani)
 nix run .#apply               # Build and apply locally (darwin-rebuild/nixos-rebuild switch)
 nix flake check               # Validate flake
+```
 
-# Remote NixOS deployment (colmena)
+### Remote Deployment (NixOS only)
+```bash
 colmena build                 # Build all NixOS hosts
 colmena apply --on <host>     # Deploy to specific NixOS host (michael, mindy, tahani)
 colmena apply                 # Deploy to all NixOS hosts
 ```
 
-## Code Style
+### Formatting
-- **Formatter**: Alejandra with tabs (run `alejandra .` to format)
+```bash
-- **Function args**: Destructure on separate lines `{inputs, pkgs, ...}:`
+alejandra .                   # Format all Nix files
-- **Imports**: Use relative paths from file location (`../../profiles/foo.nix`)
+```
-- **Attribute sets**: One attribute per line, trailing semicolons
-- **Lists**: `with pkgs; [...]` for packages, one item per line for long lists
 
-## Structure
+## Code Style
-- `hosts/<name>/` - Per-machine configs (darwin: chidi, jason | nixos: michael, mindy, tahani)
+
-- `profiles/` - Reusable program/service configs (imported by hosts)
+### Formatter
-- `modules/` - Custom NixOS/darwin modules
+- **Tool**: Alejandra
-- `lib/` - Shared constants and utilities
+- **Config**: `alejandra.toml` specifies tabs for indentation
-- `secrets/` - SOPS-encrypted secrets (`.sops.yaml` for config)
+- **Command**: Run `alejandra .` before committing
+
+### File Structure
+- **Hosts**: `hosts/<hostname>/` - Per-machine configurations
+  - Darwin: `chidi`, `jason`
+  - NixOS: `michael`, `tahani`
+- **Profiles**: `profiles/` - Reusable program/service configurations (imported by hosts)
+- **Modules**: `modules/` - Custom NixOS/darwin modules
+- **Lib**: `lib/` - Shared constants and utilities
+- **Secrets**: `secrets/` - SOPS-encrypted secrets (`.sops.yaml` for config)
+
+### Nix Language Conventions
+
+**Function Arguments**:
+```nix
+{inputs, pkgs, lib, ...}:
+```
+Destructure arguments on separate lines. Use `...` to capture remaining args.
+
+**Imports**:
+```nix
+../../profiles/foo.nix
+```
+Use relative paths from file location, not absolute paths.
+
+**Attribute Sets**:
+```nix
+options.my.gitea = {
+  enable = lib.mkEnableOption "Gitea git hosting service";
+  bucket = lib.mkOption {
+    type = lib.types.str;
+    description = "S3 bucket name";
+  };
+};
+```
+One attribute per line with trailing semicolons.
+
+**Lists with Packages**:
+```nix
+with pkgs;
+[
+  age
+  alejandra
+  ast-grep
+]
+```
+Use `with pkgs;` for package lists, one item per line.
+
+**Modules**:
+```nix
+{
+  config,
+  lib,
+  pkgs,
+  ...
+}:
+with lib; let
+  cfg = config.my.feature;
+in {
+  options.my.feature = {
+    enable = mkEnableOption "Feature description";
+  };
+  config = mkIf cfg.enable {
+    # configuration
+  };
+}
+```
+- Destructure args on separate lines
+- Use `with lib;` for brevity with NixOS lib functions
+- Define `cfg` for config options
+- Use `mkIf`, `mkForce`, `mkDefault` appropriately
+
+**Conditional Platform-Specific Code**:
+```nix
+++ lib.optionals stdenv.isDarwin [
+  _1password-gui
+  dockutil
+]
+++ lib.optionals stdenv.isLinux [
+  lm_sensors
+]
+```
+
+### Naming Conventions
+- **Option names**: `my.<feature>.<option>` for custom modules
+- **Hostnames**: Lowercase, descriptive (e.g., `michael`, `tahani`)
+- **Profile files**: Descriptive, lowercase with hyphens (e.g., `homebrew.nix`)
+
+### Secrets Management
+- Use SOPS for secrets (see `.sops.yaml`)
+- Never commit unencrypted secrets
+- Secrets files in `hosts/<host>/secrets.nix` import SOPS-generated files
+
+### Imports Pattern
+Host configs import:
+1. System modules (`modulesPath + "/..."`)
+2. Host-specific files (`./disk-config.nix`, `./hardware-configuration.nix`)
+3. SOPS secrets (`./secrets.nix`)
+4. Custom modules (`../../modules/*.nix`)
+5. Base profiles (`../../profiles/*.nix`)
+6. Input modules (`inputs.<module>.xxxModules.module`)
+
+Home-manager users import profiles in a similar manner.
