The SPring-8 Angstrom Compact free-electron LAser (SACLA) has been open for user experiments since March 2012. SACLA is the world first compact XFEL facility aiming at a general-purpose machine spread widely, which was designed to make the facility size compact as much as possible with the state-of-the art technology. Success of SACLA actually stimulates lots of researchers who are eager to utilize XFEL for their experiments to build their own XFEL facilities. Construction of compact XFEL,

This article aims at providing basic knowledge on a SACLA system and toward which SACLA is going. For this purpose the article compares approaches to XFEL among three leading XFEL projects, LCLS, European XFEL and SACLA and then, describes features of SACLA in detail.
