 #### 介绍
 This is a systemd unit generator that enables swap on zram.
-
+(With zram, there is no physical swap device. Part of the available RAM
-#### 软件架构
+is used to store compressed pages, essentially trading CPU cycles for memory.)
-软件架构说明
+To activate, install zram-generator-defaults subpackage.
 
 
 #### 安装教程
 
-1.  xxxx
+Install zram-generator rpm package:
-2.  xxxx
+
-3.  xxxx
+yum install zram-generator
+
+To install directly from sources, execute make build && sudo make install NOBUILD=true:
+
+-zram-generator binary is installed in the systemd system generator directory (usually /usr/lib/systemd/system-generators/)
+-zram-generator(8) and zram-generator.conf(5) manpages are installed into /usr/share/man/manN/, this requires ronn.
+-units/systemd-zram-setup@.service is copied into the systemd system unit directory (usually /usr/lib/systemd/system/)
+-zram-generator.conf.example is copied into /usr/share/doc/zram-generator/ You need though create your own config file at one of the locations listed above.
 
 #### 使用说明
 
-1.  xxxx
+A default config file may be located in /usr. This generator checks the following locations:
-2.  xxxx
+
-3.  xxxx
+-/run/systemd/zram-generator.conf
+-/etc/systemd/zram-generator.conf
+-/usr/local/lib/systemd/zram-generator.conf
+-/usr/lib/systemd/zram-generator.conf
+… and the first file found in that list wins.
+
+In addition, "drop-ins" will be loaded from .conf files in /etc/systemd/zram-generator.conf.d/, /usr/lib/systemd/zram-generator.conf.d/, etc.
+
+The main configuration file is read before any of the drop-ins and has the lowest precedence; entries in the drop-in files override entries in the main configuration file.
+
+See systemd.unit(5) for a detailed description of this logic.
+
+See zram-generator.conf.example for a list of available settings.
