-Buliding using tcmalloc
------------------------
+NOTE: if after building Redis with a 32 bit target you need to rebuild it
+      with a 64 bit target you need to perform a "make clean" in the root
+      directory of the Redis distribution.

+---------
 
-tcmalloc is a fast and space efficient implementation (for little objects)
-of malloc(). Compiling Redis with it can improve performance and memory
-usage. You can read more about it here:
+By default Redis compiles and links against jemalloc under Linux, since
+glibc malloc() has memory fragmentation problems.
 
-http://goog-perftools.sourceforge.net/doc/tcmalloc.html
+To force a libc malloc() build use:
 
-In order to compile Redis with tcmalloc support, install tcmalloc on your system
-and then use:
+    % make FORCE_LIBC_MALLOC=yes
 
-    % make USE_TCMALLOC=yes
+In all the other non Linux systems the libc malloc() is used by default.
 
-Note that you can pass any other target to make, as long as you append
-USE_TCMALLOC=yes at the end.
+On Mac OS X you can force a jemalloc based build using the following:
+
+    % make USE_JEMALLOC=yes
+
+Verbose build

+Redis will build with a user friendly colorized output by default.

+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!
