Asterisk realtime HowTo?

hi, sorry if this question is asked and answered already. but i can not find any info anywhere.
i m using asteriskNOW 1.5.0 distro and i want to use realtime in asterisk?
can some one point to right direction please???

Try here:
http://www.voip-info.org/wiki/view/Asterisk+RealTime

thanks for answer
but after this:
svn co http://svn.digium.com/svn/asterisk-addons/trunk asterisk-addons
i get readme file which says.
"README for Asterisk Addons

The modules that previously lived here are now in the addons directory of the
main Asterisk source tree.
"
and that is for 1.2 version.

The above posted link was just a suggestion where you could read about Asterisk RealTime.

Do NOT follow the instructions BEFORE you fully understand how Asterisk works.

If you don’t know how to download the correct asterisk-addons for your version of Asterisk you will get a lot of broken pieces to work with.

I will not post anything else here in this thread because the scope is not related to FreePBX.

if you just read about even title line
it says HowTo
and i have test system where i do what ever i want without going near to prod.
but thanks for your comments
