-Do a high quality implementation of workplan KEY-WP-0001-keycape-implementation.md as follows:
-
-Requirements and Boundaries
-- Keep the scope of the workplan
-- Use documents in spec/ and wiki/ folder to understand the big picture
-- Document important architecture decisions as ADRs in the architecture/ folder
-- Save relevant parts of documentation you need to grab online to the research/ folder
-- Keep the state-hub up to date with task completions
-- If stuck and when running out of iterations document what went wrong in problems/ folder
-
-WHILE TDD-Loop for all tasks:
-1) RED: write test → run → fail
-2) GREEN:  implement minimal code → run → pass
-3) REFACTOR: refactor → run → pass
-REPEAT
-
-Success Criteria:
-- No linter errors
-- All tasks and requirements of workplan implemented
-- Documentation updated showing how the application works
-- Check Workstream DoD from the state-hub policies
-
-Refine until all succes-criteria have been met, otherwise 
-output <promise>HEUREKA</promise> when done!

 ## Architecture
 
@@ -37,6 +30,153 @@ elia
 
 **Expanded mode:** Replace KeyCape with Keycloak. Same profile, same tests pass.
 
+## Quick Start
+
+```bash
+# Start the dev stack (KeyCape + LLDAP + Authelia + privacyIDEA)
+make dev
+
+# Build the server binary
+make build
+
+# Run all tests
+make test
+```
+
+## Configuration
+
+KeyCape uses a YAML config file. See `config/dev-config.yaml` for a full example.
+
+```yaml
+issuer: "https://auth.netkingdom.local"
+port: 8080
+tokenLifetime: "15m"
+privateKeyPem: "/etc/keycape/key.pem"
+environment: "production"
+
+lldap:
+  url: "ldap://lldap:389"
+  bindDN: "cn=admin,dc=netkingdom,dc=local"
+  bindPW: "secret"
+  baseDN: "dc=netkingdom,dc=local"
+
+authelia:
+  baseURL: "https://authelia.local"
+  clientId: "keycape"
+  clientSecret: "secret"
+  redirectURI: "https://auth.netkingdom.local/authorize/callback"
+
+privacyidea:
+  baseURL: "https://privacyidea.local"
+  adminToken: "secret"
+  realm: "netkingdom"
+
+clients:
+  - clientId: "my-app"
+    displayName: "My Application"
+    redirectUris: ["https://myapp.local/callback"]
+    allowedScopes: ["openid", "profile", "email", "groups"]
+    grantTypes: ["authorization_code"]
+    clientType: "public"
+```
+
+Config is validated at startup — the server exits 1 with validation errors if config is invalid.
+
+## Endpoints
+
+| Endpoint | Description |
+|---|---|
+| `GET /.well-known/openid-configuration` | OIDC discovery document |
+| `GET /jwks` | RS256 public key in JWK Set format |
+| `GET /authorize` | Authorization endpoint (PKCE required) |
+| `GET /authorize/callback` | Authelia callback handler |
+| `POST /token` | Token exchange (authorization_code only) |
+| `GET /userinfo` | Userinfo endpoint (Bearer token required) |
+| `GET /healthz` | Health check → `{"status":"ok","version":"0.1.0"}` |
+
+## Profile Constraints
+
+KeyCape enforces the NetKingdom IAM Profile. Violations return structured errors:
+
+| Error type | Meaning |
+|---|---|
+| `feature_not_supported_by_profile` | Feature is outside the profile entirely |
+| `available_in_keycloak_mode_only` | Available in expanded mode, not lightweight |
+| `rejected_for_profile_safety` | Would weaken security guarantees |
+| `invalid_profile_usage` | Supported feature used incorrectly |
+
+Enforced boundaries: no implicit flow, no wildcard redirect URIs, no dynamic client
+registration, no identity brokering, PKCE S256 required.
+
+## Migration Tools
+
+KeyCape ships migration tools for the two orthogonal migration dimensions:
+
+**IAM migration (KeyCape → Keycloak):**
+```bash
+# Export canonical data from LLDAP
+./lldap-export --url ldap://lldap:389 --bind-dn cn=admin,... --output canonical-export.yaml
+
+# Transform to Keycloak realm import
+./keycape-to-keycloak --input canonical-export.yaml --realm netkingdom --output keycloak-realm-import.json
+```
+
+**Directory migration (LLDAP → OpenLDAP / 389DS / AD):**
+```bash
+./lldap-to-ldap --input canonical-export.yaml --target openldap --base-dn dc=netkingdom,dc=local --output migration.ldif
+```
+
+Both migrations are independent. Perform either or both without affecting privacyIDEA MFA enrollment.
+
+## LDAP Schema Validator
+
+```bash
+# Validate in CI mode (strict)
+./validator --mode ci --input directory-snapshot.yaml
+
+# Validate before provisioning
+./validator --mode provisioning --input users.yaml
+```
+
+Validates: DN structure, required attributes, no unknown attributes, user references,
+no cyclic groups, username uniqueness, email format.
