Please note I am new to simba(as with a lot of us) so help from the long time simba users on sythe would be nice.
1.Create a account on villavu.com you need to do this to access scripts on Villavu
2.Download simba
here
3.Install It
4. Click view<extensions Click associate.sex, enable it. Click extension.sex and enable it. Click msi.sex and enable it. Click paster.sex and enable it. Click srl.sex and enable it.
5.Update all of the extensions.
6.Then click tools>update and restart Simba
7.Download Smart
here. Smart allows you to bot without it using your mouse!
After you download it extract the content from smart binaries, and copy it. Then put it in the plugin folder under simba replacing everything
When you open Simba back up test if everything is working using this script.
Code:
program new;
{$i srl/srl/misc/smart.scar}
{$i srl/srl.simba}
begin
SetupSRL;
end.
Thanks to Shuttleu on Villavu for this code.
Then click the green arrow
This should appear in the debug box
Code:
Runescape is loading, Please Wait.
Then something called smart should pop up(after a few seconds)
Then click disable smart and set your settings to these(you only need to do this once)

How to actually get botting.
Look for a script that fits your purposes in the Public Scripts section located
here
Then download the latest version of the script via the link at the bottom of the original post(It's open sourced so it's safe)
Now to fill in the set up.
Code:
Players[0].Name := ''; Put in your username/email in the ''
Players[0].Pass := ''; Put in your pass in the ''
Players[0].Pin := ''; Put you bank pin in the '' (if you don't have one leave it blank)
For each script they have differing set ups so follow the instructions in the scripts thread and in the script.
