Like it was correctly mentioned above, each of the add-on's package contains a README.txt
file which you should follow
for the proper installation.
Also, for making the life easier, we have the Compiler
tool, which does the compilation job for you in a few seconds. But again, after getting a compiled version, you should follow the README.txt attached to this package, to install everything properly.
For those not advanced technically, we are also providing Premium Services
of installation, customization and compilation jobs.
