# Cleanup

So you've made all your SSDTs but now there's one thing left: Adding them to Opencore

The 2 main locations:

* EFI/OC/ACPI (Only **.aml** files, reminder to [compile your SSDTs](/Manual/compile.md))
* config.plist -> ACPI -> Add

You can save yourself some work with the config.plist by running Cmd/Ctrl+R in ProperTree. **Reminder do not add your DSDT.aml to your EFI**

Users of `FixHPET` will also need to merge oc_patches.plist into their config.plist

Steps to do this:

* Open both files,
* Delete the `ACPI -> Patch` section from config.plist
* Copy the `ACPI -> Patch` section from patches.plist
* Paste into where old patches were in config.plist
