Welcome to the Starport.
However, keep searching (I could just tell you but that'd force us to go through ancient topics over and over again for every newcomer, so I hope you understand). It sure is here somewhere and more than once. You may want also to check our TLR archive.

There are dozens if not hundreds of those who did and I doubt every single one of them found out how to all on their own. The solution must be posted somewhere.
FYI on my second search up here on this site I found this.

There are things that about every modder does. I remember not knowing things like these myself and I know that asking politely will give you the answers quicker than any search up here, thanks to the very active community. However it is simpler for us to progress if those who are joining us are learning from our old and solid knowledge before dragging us to reveal it again. Next time, don't be lazy and search a second time if the solution doesn't get obvious with the first

Also, before you ask, the Resource Hacker is available in our downloads and probably there are some threads covering basic functions you'd need to know for this particular one and perhaps some other tasks.

As said before, Welcome to the Starport!
Regards
Gisteron
