You'll probably need to search for some tuts on the net to know what you need to export (3 files). And how to compile those files to make an mdl that will be usable by the source engine.
you need to learn how to use it more efficiently . google can use operations such as quotations to match exact phrase minus sign to remove results from a ceratain keyword and the plus sign to add stuff from other keyword if u typed
"mdl decompiler" +hl2
im sure u would have found it.
