 ## Tutorial: From Local Testing to Production
 
 This section walks you through a complete example, from running Paskia locally to protecting a real site in production.
 
-### Step 1: Local Testing
+### Step 1: Production Configuration
-
-For development and testing, run Paskia without any arguments:
-
-```fish
-paskia
-```
-
-This starts the server on [localhost:4401](http://localhost:4401) with passkeys bound to `localhost`. On first run, Paskia prints a registration link for the Master Admin—click it to register your first passkey.
-
-### Step 2: Production Configuration
 
 For a real deployment, configure Paskia with your domain name (rp-id). This enables SSO setup for that domain and any subdomains.
 
-```fish
+```sh
-paskia --rp-id=example.com --rp-name="Example Corp" --save
+uvx paskia --rp-id=example.com --rp-name="Example Corp"
 ```
 
-This binds passkeys to the rp-id, allowing them to be used there or on any subdomain of it. The `--rp-name` is the branding shown in UI and registered with passkeys for everything on your domain (rp id). The `--save` option stores these settings in the database, so future runs only need `paskia --rp-id example.com`, of which we will make use of with the systemd config later on.
+This binds passkeys to the rp-id, allowing them to be used there or on any subdomain of it.

 ### Optional: Dedicated Authentication Site
 
-By default, Paskia serves login dialogs and admin interface at the `/auth/` path on each protected site. For a cleaner setup, you can use a dedicated authentication subdomain instead. We assume you have your DNS setup for that domain or a wildcard of all subdomains to current machine.
-

 The JSON variants set headers automatically, with body and response in JSON.
 
+### Timeout Settings
+
+Paskia exports a mutable settings object for defaults used by fetch/auth/session validation timers. Default values shown below.
+
+```js
+import { settings } from 'paskia'
+
+// General fetch timeout used by apiFetch/apiJson/fetchJson when no timeout is passed
+settings.fetch_ms = 10000
+
+// Fetch timeout used by SessionValidator (/auth/api/validate is fast)
+settings.auth_ms = 1000
+
+// SessionValidator polling and idle timers
+settings.poll_ms = 60000
+settings.idle_ms = 300000
+```
+
+You can still override timeout per request:
+
+```js
+await apiJson('/api/upload', { method: 'POST', body: data, timeout: 30000 })
+```
+
 ### Authentication Overlay
 
 Normally you use apiJson/apiFetch and they handle this automatically. If you need to wire it yourself, on a 401/403 response that includes `auth.iframe`, call `showAuthIframe(...)` and then retry the original request.
