Hi, I had the same question yesterday lol.

Ok, so you've downloaded rsbot, and a script you want to use :laugh:
If you received a big text in the forum, copy past it in a txt file, then save the txt file with the name you think it got to have ex: if its a auto flax spinner, just name it autoFlax.java don't forgot the JAVA!!!Take the java type file you've download( the script) it looks like a txt file.
take it and paste it to rsbot/scripts ( to the scripts folders)
If you followed a certain number of guides you got to have java jdk javatools or something. then when you put the file in the folder, go back, and press the compile file, if you see an error and it says something weird, read it, there should be a name
ex: LumbFlaxSpinner.
Then the file in the scripts folder, you got to rename it to the name you saw before ( for me i would rename the file to: LumbFlaxSpinner) if you have other files that you downloaded and dont renamed them, the compile file will not finish. when you renamed all your download files, press compile, it will make another file that has the same name as the downloaded file from before but it will be a class file. Then go to rsbot, go to bot (top left corner) and run script then search your script in the list. voila!

I hope i helped.
