 # Project Readme Hints
 
-This is the initial readme hints file.
+## UI Components
+Always check dees-catalog for available elements before implementing custom solutions:
+- Documentation: https://code.foss.global/design.estate/dees-catalog
+- Key components: `dees-modal`, `dees-button`, `dees-input-*`, `dees-form`, etc.
+
+### dees-input-* Event Pattern
+All dees-input components use **RxJS Subjects** for value changes, NOT DOM events:
+```typescript
+// Subscribe to value changes in firstUpdated():
+const inputElement = this.shadowRoot.querySelector('dees-input-text');
+inputElement.changeSubject.subscribe((element) => {
+  const value = element.value;
+  // handle value change
+});
+```
+- Do NOT use `@changeValue` or similar DOM events - they don't exist
+- The Subject emits the element itself, access value via `element.value`
+
+## Project Structure
+- `ts_web/elements/account/` - Account dashboard components
+- `ts_web/states/` - State management (accountstate, idp.state)
