+Allocator
+---------
+
+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.
+
+To force compiling against libc malloc, use:
+
+    % make MALLOC=libc
+
+To compile against jemalloc on Mac OS X systems, use:
+
+    % make MALLOC=jemalloc
+
+Verbose build
+-------------

+Redis will build with a user friendly colorized output by default.
+If you want to see a more verbose output use the following:

+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!
