Site: how-tos and the FAQ (phase 3)

Eight how-to recipes and a FAQ page with a list of its questions, from the
README, the milestone documents and the Apps' source. The guide templates
become generic (the parent section gives the eyebrow, title and pager).

+1. **Add the network first.** In **Settings → Wi-Fi**, choose **Add a network**, pick it and type the password. (A hidden network has its own entry, which asks for the name first.)
+2. **Open the network's page:** <kbd>Enter</kbd> on it in the list of saved networks.
+3. **Set *IP address* to *Fixed*.** The address, the prefix and the gateway start from what the network is giving the device at that moment, so you only change what is wrong.
+   - **Address:** four numbers, like `10.39.39.13`.
+   - **Prefix:** 1 to 30. 24 is 255.255.255.0.
+   - **Gateway:** optional; empty means none.
+4. **Leave the page.** The setting is checked and applied then; a bad address is refused with the reason.
+5. **Check it.** Back in **Settings → Wi-Fi**, <kbd>Enter</kbd> on **Status** shows the address, the mask, the gateway, the DNS and NTP servers, and where each came from.
+
+## DNS and time
+
+**DNS and NTP** on the Wi-Fi page holds two DNS servers (9.9.9.9 and 1.1.1.1 by default) and two NTP servers (pool.ntp.org and time.cloudflare.com). They are used on Fixed networks, or on every network if **Always use my DNS** is on. Leave a second server empty if you only have one. IPv4 only.
+
+To go back, set *IP address* to *Automatic*. **Forget this network** is at the bottom of the same page.
