 Building Redis
 --------------
 
+Redis can be compiled and used on Linux, OSX, OpenBSD, NetBSD, FreeBSD.
+We support big endian and little endian architectures.
+
+It may compile on Solaris derived systems (for instance SmartOS) but our
+support for this platform is "best effort" and Redis is not guaranteed to
+work as well as in Linux, OSX, and *BSD there.

 It is as simple as:
 
     % make
 
-Redis is just a single binary, but if you want to install it you can use
-the "make install" target that will copy the binary in /usr/local/bin
-for default. You can also use "make PREFIX=/some/other/directory install"
-if you wish to use a different destination.

 You can run a 32 bit Redis binary using:
 
     % make 32bit

+Selecting a non-default memory allocator when building Redis is done by setting
+the `MALLOC` environment variable. Redis is compiled and linked against libc
+malloc by default, with the exception of jemalloc being the default on Linux
+systems. This default was picked because jemalloc has proven to have fewer
+fragmentation problems than libc malloc.

+Installing Redis
+-----------------
+
+In order to install Redis binaries into /usr/local/bin just use:
+
+    % make install
+
+You can use "make PREFIX=/some/other/directory install" if you wish to use a
+different destination.
+
+Make install will just install binaries in your system, but will not configure
+init scripts and configuration files in the appropriate place. This is not
+needed if you want just to play a bit with Redis, but if you are installing
+it the proper way for a production system, we have a script doing this
+for Ubuntu and Debian systems:
+
+    % cd utils
+    % ./install_server
+
+The script will ask you a few questions and will setup everything you need
+to run Redis properly as a background daemon that will start again on
+system reboots.
+
+You'll be able to stop and start Redis using the script named
+/etc/init.d/redis_<portnumber>, for instance /etc/init.d/redis_6379.

 Enjoy!
