+Design
+------
+
+I made the site as inclusive as possible. Tested using multiple screen readers (Orca, TalkBack, Apple VoiceOver, Windows Narrator, NVDA), and I regularly test with the following browsers/engines. Testing in a browser does not imply any sort of endorsement; I just want to meet people where they're at.
+
+Desktop:
+
+- Gecko: Nightly, Stable, ESR, and sometimes Pale Moon
+- the Tor Browser
+- Blink: latest Chromium snapshot, stable, and QtWebEngine
+- WebKit: Webkit2GTK3
+- NetSurf
+- SerenityOS Browser
+- Very old WebKit via rekonq (Qt4 QtWebKit)
+- KHTML
+- Servo
+- Trident, if I have access to a Windows machine that has Edge with "IE Mode".
+
+For all the above options, I test "reading mode" whenever it's available.
+
+Mobile:
+
+- Android: Blink, Gecko, Tor Browser
+- iOS WebKit: latest stable version, iOS 12, iOS 10 on an iPhone 5. Also test Reader Mode.
+- TODO: try a KaiOS device.
+
+Smart watches:
+
+- Borrowed an Apple Watch to try the embedded browser.
+- TODO: test on a Tizen or Wear OS device's browser.
+
+Everything works well in all the above browsers.
