 ### UMD Bundle (Global Variable)
 
+If you use the legacy UMD bundle (`solid-ui.js` / `solid-ui.min.js`), `rdflib` must define `window.$rdf` before `solid-ui` loads. If `rdflib` is missing, `solid-ui` will throw `ReferenceError: $rdf is not defined`.

 Load via `<script>` tags and access through global variables `window.$rdf`, `window.SolidLogic`, and `window.UI`.

-### Development new components
+## Web Components
+
+solid-ui ships self-contained Lit-based custom elements as subpath exports. Each component is independently importable, registers its custom element on import, and ships its own styles encapsulated in a Shadow DOM.
+
+> Component UMD bundles do not export a shared global like `window.UI`. They only register the custom element on import, while the legacy main bundle still provides the `UI` global.
+
+### solid-ui-header
+
+A header bar with branding, auth state (logged-out / logged-in), an account dropdown, and a desktop-only help menu.
+
+**Subpath export:** `solid-ui/components/header`
+
+```typescript
+import { Header } from 'solid-ui/components/header'
+import type { HeaderMenuItem, HeaderAccountMenuItem, HeaderAuthState } from 'solid-ui/components/header'
+```
+
+```html
+<solid-ui-header theme="dark" layout="desktop" brand-link="/">
+  <a slot="help-menu" href="/help">Help</a>
+</solid-ui-header>
+```
+
+Importing this module automatically registers `<solid-ui-header>` as a custom element.
+
+### solid-ui-login-button
+
+A standalone login button that encapsulates the Solid OIDC login flow and emits `login-success` when authentication succeeds.
+
+**Subpath export:** `solid-ui/components/login-button`
+
+```typescript
+import { LoginButton } from 'solid-ui/components/login-button'
+```
+
+```html
+<solid-ui-login-button label="Log in" issuer-url="https://solidcommunity.net"></solid-ui-login-button>
+```
+
+```typescript
+const loginButton = document.querySelector('solid-ui-login-button') as LoginButton
+loginButton.addEventListener('login-success', (event: CustomEvent) => {
+  console.log('Logged in as', event.detail.webId)
+})
+```
+
+### solid-ui-signup-button
+
+A standalone sign-up button that opens a signup URL in a new browser tab.
+
+**Subpath export:** `solid-ui/components/signup-button`
+
+```typescript
+import { SignupButton } from 'solid-ui/components/signup-button'
+```
+
+```html
+<solid-ui-signup-button label="Get a Pod" signup-url="https://solidproject.org/get_a_pod"></solid-ui-signup-button>
+```
+
+### Component build pipeline
+
+Web components use a two-stage build to produce a clean public runtime layout while keeping internal TypeScript artifacts separate:
+
+1. **webpack** (`npm run build-dist`) bundles each component entrypoint and emits the runtime files to `dist/components/<name>/index.js` and `dist/components/<name>/index.esm.js`.
+2. **tsc** (`npm run build-js`) emits internal declaration and JS artifacts mirroring the source tree under `dist/v2/components/<name>/`.
+3. **`scripts/build-component-dts.mjs`** (runs automatically after tsc as part of `postbuild-js`) writes thin public declaration wrappers at `dist/components/<name>/index.d.ts`, re-exporting from the internal `dist/v2/components/<name>/` output.
+
+This keeps the `package.json` subpath export fully aligned while exposing only the public `dist/components/...` layout:
+
+```json
+"./components/header": {
+  "types":   "./dist/components/header/index.d.ts",
+  "import":  "./dist/components/header/index.esm.js",
+  "require": "./dist/components/header/index.js"
+}
+```
+
+Consumers never import from `dist/v2/components/...`; that path is an internal build artifact only.

+## Generative AI usage
+The SolidOS team is using GitHub Copilot integrated in Visual Studio Code. 
+We have added comments in the code to make it explicit which parts are 100% written by AI. 
+
+### Prompt usage history:
+
+* Raptor mini: If I want to make the header a web component with a self contained CSS which only consumes CSS variables from a theme, how would I do this? 
+
+* Raptor mini: Go ahead and create a header web component, for backward compatibility keep the current code too.
+In the new header component I need to be flexible and receive from consumer - the layout (mobile or desktop) and the theme (light or dark) and its according CSS variables for light to dark.
+
+* Raptor mini: Propose code. how about webpack config for distribution?
+
+* Raptor mini: pls add a readme in the component documenting it usage and test and all
+
+* Raptor mini: the helpMenuList should be menu items inside the help icon drop down menu
+
+* Raptor mini: When I am not logged in I want the header to display: Log in button and Sign Up button.
+When the user is logged in, there is only one button, a drop down button called Accounts. The icon of the button is the avatar of the profile and it displays a list of available accounts of the user.
+I want this all to be presented flexible in the component.
+
+* Claude Sonnet 4.6: create a LitElement also for the signupButton in the SignupButton.ts based on the signup.js code and wire it into the header like you did the loginButton.
+
+* Raptor mini: when we are on layout mobile we do not want to display the help menu at all.
