+# Scanning
+
+SANE (Scanner Access Now Easy) may be used to acquire images from scanners.
+
+As a prerequisite, install the `sane` package. To list discovered scanners:
+
+```
+$ scanimage -L
+```
+
+For additional options, consult
+[scanimage(1)](https://man.voidlinux.org/scanimage.1).
+
+## Scanner Drivers
+
+If the scanner is not discovered by `scanimage -L`, it may require a driver.
+
+### Driverless scanning
+
+Many different models of scanner support "driverless" scanning via the AirScan
+or WSD protocols. The `sane-airscan` driver may be utilized in these cases. This
+should cover the vast majority of modern scanner hardware.
+
+Applications acting as frontends to SANE will also use the `sane-airscan` driver
+if present, but do not depend on it, so it's recommended to install this and
+have it available.
+
+### Other scanner drivers
+
+If the scanner is not detected with `sane-airscan`, a manufacturer-specific
+driver may be required.
