 https://periph.io/x/host/v3/ftdi (or later) instead.
 
@@ -14,3 +11,34 @@ But if you really want, here it goes:
 
 This Go package includes third party software. See
 [third_party/README.md](third_party/README.md).
+
+## Configuration
+
+See https://periph.io/device/ftdi/ to configure the host to be able to use this
+driver.
+
+## Availability
+
+On darwin_amd64, linux_amd64 linux_arm (v6, v7 compatible) and linux_arm64 (v8),
+cgo is required. If cgo is disabled (via `CGO_ENABLED=0`), all functions in this
+driver return error [NoCGO](https://periph.io/x/d2xx#NoCGO).
+
+On Windows, cgo is not required. If the dynamic library is not found at runtime,
+[Missing](https://periph.io/x/d2xx#Missing) is returned.
+
+## bcm2385
+
+On linux_arm (v6), hard-float is required. For cross compilation, this
+means arm-linux-gnueabihf-gcc is preferred to arm-linux-gnueabi-gcc. Using
+hardfloat causes a segfault on Raspberry Pi 1, Zero and Zero Wireless. It is
+recommended to disable this driver if targeting these hosts, see below.
+
+## Disabling
+
+To disable this driver, build with tag `no_d2xx`, e.g.
+
+```
+go install -tags no_d2xx periph.io/x/cmd/gpio-list@latest
+```
+
+This will behave has if cgo was disabled, even on Windows.
