+### File replacements by Angular build configuration
+
+This note summarizes current file replacements defined in `angular.json` and the simplified approach using a centralized brand config.
+
+#### Current simplified replacements
+
+- **me**
+  - `src/app/brand.config.ts` → `src/app/brand.config.me.ts`
+- **ma** (default)
+  - `src/app/brand.config.ts` → `src/app/brand.config.ma.ts`
+- **dc**
+  - `src/app/brand.config.ts` → `src/app/brand.config.dc.ts`
+- **me-production**
+  - `src/environments/environment.ts` → `src/environments/environment.prod.ts`
+  - `src/app/brand.config.ts` → `src/app/brand.config.me.ts`
+- **ma-production**
+  - `src/environments/environment.ts` → `src/environments/environment.prod.ts`
+  - `src/app/brand.config.ts` → `src/app/brand.config.ma.ts`
+- **dc-production**
+  - `src/environments/environment.ts` → `src/environments/environment.prod.ts`
+  - `src/app/brand.config.ts` → `src/app/brand.config.dc.ts`
+
+#### Using configuration flags
+
+Build commands select replacements via `--configuration`:
+
+- `ng serve --configuration=me`
+- `ng build --configuration=me`
+- `ng serve --configuration=dc`
+- `ng build --configuration=me-production`
+- `ng build --configuration=dc-production`
+
+#### Brand configuration files
+
+Each brand has its own config file that exports the same `BRAND_CONFIG` constant:
+
+**`src/app/brand.config.ts`** (default - MA)
+
+```typescript
+export const BRAND_CONFIG: BrandConfig = {
+  logoPath: 'assets/images/mhc_logo.svg',
+  faviconPath: 'assets/images/favicon.png',
+  rosterTemplatePath: 'assets/roster_upload_template.xlsx',
+  zipCodeDataPath: 'data/zipCode.json',
+};
+```
+
+**`src/app/brand.config.me.ts`** (Maine)
+
+```typescript
+export const BRAND_CONFIG: BrandConfig = {
+  logoPath: 'assets/images/logo_me.svg',
+  faviconPath: 'assets/images/favicon_me.png',
+  rosterTemplatePath: 'assets/roster_upload_template_me.xlsx',
+  zipCodeDataPath: 'data/zipCodeME.json',
+};
+```
+
+**`src/app/brand.config.dc.ts`** (District of Columbia)
+
+```typescript
+export const BRAND_CONFIG: BrandConfig = {
+  logoPath: 'assets/images/mhc_logo.svg', // Keep default for now
+  faviconPath: 'assets/images/favicon.png', // Keep default for now
+  rosterTemplatePath: 'assets/roster_upload_template.xlsx', // Keep default for now
+  zipCodeDataPath: 'data/zipCode.json', // Keep default for now
+};
+```
+
+#### Implementation
+
+Components now reference `BRAND_CONFIG` instead of hardcoded paths:
+
+- `HeaderComponent` uses `BRAND_CONFIG.logoPath`
+- `EmployerDetailsComponent` exposes `brand = BRAND_CONFIG`
+- Template binds roster template link to `brand.rosterTemplatePath`
+
+#### Benefits of this approach
+
+- **Single file replacement**: Only swap `brand.config.ts` per brand
+- **No code changes needed**: Components automatically use the correct paths
+- **Easy maintenance**: Update paths in one place per brand
+- **Production builds**: Combine brand config + environment swap
+- **Future expansion**: Add new brand-specific assets by updating config files
+
+#### Example npm scripts
+
+```json
+{
+  "scripts": {
+    "start:me": "ng serve --configuration=me",
+    "build:me": "ng build --configuration=me",
+    "build:me:prod": "ng build --configuration=me-production",
+    "start:dc": "ng serve --configuration=dc",
+    "build:dc:prod": "ng build --configuration=dc-production"
+  }
+}
+```
+
+#### Next steps
+
+1. Add brand-specific assets (logos, favicons, templates, zip code data)
+2. Update brand config files with correct paths
+3. Test builds with `--configuration` flags
+4. Consider adding brand-specific SCSS variables for theming
