+Dynamic Web TWAIN's main feature is interacting with imaging devices like scanners and cameras via different scanning APIs like TWAIN, ICA, SANE and DirectShow. As long as the scanner is supported by these APIs, Dynamic Web TWAIN can use them.
+
+In this section, we'll look at these APIs.

-`TWAIN Scanners` refer to image scanners and document scanners that have drivers following the TWAIN standard.
-
-### Facts about TWAIN
-
 * TWAIN is an application programming interface (API) and communication protocol that regulate communication between software and digital imaging devices, such as image scanners and digital cameras. 
 
-* TWAIN is supported on Microsoft Windows, Linux, and macOS X. However, based on our experience and the experience of many customers, TWAIN only works well on Windows. On Linux, [SANE](#sane-scanners) is the better and preferred alternative; on macOS, [ICA](#ica-scanners) is the better and preferred alternative.

 * TWAIN is actively maintained by the non-profit [TWAIN Working Group](https://www.twain.org/). Members of the group consist of scanner vendors and imaging software vendors, including FUJITSU, Panasonic, Epson, HP, ExactCODE, LEADTOOLS, and of course, Dynamsoft.
 
 * TWAIN is [the most commonly used protocol](https://www.twain.org/why-twain/) for image capturing and processing. Almost all scanners on the market come with a TWAIN driver and are supported by TWAIN applications like `Dynamic Web TWAIN`.

-`ICA Scanners` refer to image scanners that have drivers designed in accordance with the [ImageCaptureCore Framework](https://developer.apple.com/documentation/imagecapturecore).
-
-### Facts about ICA
-
-* ICA is a framework from Apple designed to "Browse for media devices and control them programmatically from your app."

-`SANE Scanners` refer to image scanners that have drivers designed in accordance with the [SANE API](http://www.sane-project.org/).
-
-### Facts about SANE
-
-* SANE stands for "Scanner Access Now Easy" and is an application programming interface (API) that provides standardized access to any raster image scanner hardware.
+* [SANE](http://www.sane-project.org/) stands for "Scanner Access Now Easy" and is an application programming interface (API) that provides standardized access to any raster image scanner hardware.
 
 * SANE is supported on multiple Linux distributions.
 
 * As of version 16.1.1, `Dynamic Web TWAIN` supports SANE v1.0.25.
