 ## Environment Configuration
 
-Uses `companies.json` for multi-account configuration. Each company entry contains `keyID`, `issuerID`, and `privateKeyPath`.
+Three config methods (checked in priority order):
+1. `--companies /path/to/companies.json` (CLI argument)
+2. `ASC_MCP_COMPANIES` env var → path to JSON file
+3. Default JSON: `~/.config/asc-mcp/companies.json`
+4. `ASC_COMPANY_1_KEY_ID`, `ASC_COMPANY_2_KEY_ID`... (multi-company env vars)
+5. `ASC_KEY_ID` + `ASC_ISSUER_ID` + `ASC_PRIVATE_KEY_PATH` (single company env vars)
+
+Each company needs: `keyID`, `issuerID`, `privateKeyPath` (path to `.p8` file).

 ## Testing
 
-Test mode (`--test` flag) performs:
-1. Lists app versions to find editable one
-2. If found, updates What's New field
-3. Verifies the update succeeded
+### Unit Tests (Swift Testing)
+
+```bash
+swift test    # Run all 345 tests across 28 suites
+```
+
+Test categories:
+- **Worker tests** (`Tests/ASCMCPTests/Workers/`):
+  - `WorkerToolDefinitionsTests` — tool count and name correctness per worker
+  - `WorkerRoutingTests` — unknown tool throws `MCPError.methodNotFound`
+  - `ParameterValidationTests` — missing required params returns `isError`
+- **Model tests** (`Tests/ASCMCPTests/Models/`) — decode, roundtrip, edge cases
+- **Service tests** (`Tests/ASCMCPTests/Services/`) — JWT generation
+- **Helper tests** (`Tests/ASCMCPTests/HelperTests/`) — JSON formatting, pagination
+- **Core tests** (`Tests/ASCMCPTests/Core/`) — ASCError, config models
+
+Test infrastructure: `TestFactory` (`Tests/ASCMCPTests/Helpers/TestHelpers.swift`) — creates mock HTTPClient, JWTService, loads fixtures.
+
+### Integration Test Mode
+
+```bash
+./.build/debug/asc-mcp --test              # Test company switching
+./.build/debug/asc-mcp --test-metadata      # Test metadata update
+```
 
 ## Common Tasks
 
-### Adding New Tool
+### Adding New Tool to Existing Worker
+
+1. Implement handler in `Worker+Handlers.swift`
+2. Add tool definition in `Worker+ToolDefinitions.swift`
+3. Register in worker's `getTools()` array
+4. Add case to worker's `handleTool()` switch
+5. No changes needed in WorkerManager — it automatically routes by prefix
+
+### Adding New Worker
 
-1. Implement method in appropriate Worker (e.g., `AppsWorker+Handlers.swift`)
-2. Add tool definition method in Worker's tool definitions file (e.g., `AppsWorker+ToolDefinitions.swift`)
-3. Register the tool in Worker's `getTools()` method
-4. Add case to Worker's `handleTool()` switch
-5. No changes needed in WorkerManager - it automatically routes by prefix
+1. Create directory `Workers/MyWorker/` with 3 files:
+   - `MyWorker.swift` — class, `getTools()`, `handleTool()` switch
+   - `MyWorker+ToolDefinitions.swift` — tool schemas
+   - `MyWorker+Handlers.swift` — handler implementations
+2. Create models in `Models/MyDomain/MyModels.swift`
+3. Register in `WorkerManager.swift`: property, init, `registerWorkers()` (ListTools + CallTool), `reinitializeWorkers()`, getter method
+4. Add worker name to `EntryPoint.swift` → `validWorkers` set
+5. Add prefix description to `Application.swift` → server instructions
+6. Update tests: `WorkerToolDefinitionsTests`, `WorkerRoutingTests`, `ParameterValidationTests`
