MEAT is just a kitchen sink modpack with tons of magic mods and a little bit of immersive/low tech mods and alot of exploration
i will try to integrate HQM but i guess it will more be a guidline through the mods rather than real questing.
to start with you need to download the .zip file or pull the repos
this should then download once downloaded you can put it anywhere i will use my desktop for this example
then extract the files. the easiest way to do this is to right click and use extract to
now you should have a file named the same as the .zip from earlier now we need to build the version we do this by using the commands below you can use shift right click to open a comand prompt in the folder
Terminal/Command Prompt:
./gradlew buildAll
Windows syntax:
gradlew buildAll
Other possible parameters: buildAll, buildServer, buildClient
and done
