 # Migrating from LDLib SyncData
 
+### Simple example
+
+This simple example covers the majority of use cases when adding sync/save fields to a standard machine, machine trait or cover.
+
+#### With LDLib:
+```java
+class CustomMachine extends SimpleTieredMachine {
+    protected static final ManagedFieldHolder MANAGED_FIELD_HOLDER = new ManagedFieldHolder(CustomMachine.class,
+            SimpleTieredMachine.MANAGED_FIELD_HOLDER);
+
+    @Override
+    public ManagedFieldHolder getFieldHolder() {
+        return MANAGED_FIELD_HOLDER;
+    }
+
+    @Getter 
+    @Persisted
+    @DescSynced
+    @RequireRerender
+    protected int customIntValue;
+    
+    @Persisted(key = "customNBTKey")
+    protected String customStringValue;
+
+    public void setCustomIntValue(int newValue) {
+        this.customIntValue = newValue;
+    }
+}
+```
+
+#### New System:
+```java
+class CustomMachine extends SimpleTieredMachine {
+    @Getter 
+    @SaveField
+    @SyncToClient
+    protected int customIntValue;
+    
+    @SaveField(nbtKey = "customNBTKey")
+    protected String customStringValue;
+    
+    public void setCustomIntValue(int newValue) {
+        this.customIntValue = newValue;
+        ////// IMPORTANT: markClientSyncFieldDirty must be called to update client synced fields.
+        getSyncDataHolder().markClientSyncFieldDirty("customIntValue");
+    }
+}
+
+```
+
 ### General migration guidelines
 
 - Remove all `ManagedFieldHolder` fields.

+## Machine Trait Refactor
+
+A new system for attaching traits and custom behaviour to machines has been added, and many machine interfaces and traits now use this new system.
+
+### New System Example
+
+Example of the new `AutoOutputTrait`
+
+```java
+public class CustomDrumMachine extends MetaMachine {
+
+  protected final NotifiableFluidTank tank;
+  public final AutoOutputTrait autoOutput;
+
+  public DrumMachine(BlockEntityCreationInfo info, int capacity) {

+    
+    // Registers an auto output trait that provides fluid output behaviour for the given fluid tank.
+    this.autoOutput = AutoOutputTrait.ofFluids(this, tank);
+    
+    autoOutput.setFluidOutputDirection(Direction.DOWN);
+    autoOutput.setFluidOutputDirectionValidator(d -> d == Direction.DOWN);
+  }
+  
+  // Any code can query traits from a machine 
+  public static void queryTraits(MetaMachine machine) {
+      
+      // Returns a trait with the given type, or null.
+      AutoOutputTrait autoOutputTrait = machine.getTraitHolder().getTrait(AutoOutputTrait.TYPE);
+
+      Optional<RecipeLogic> recipeLogicOptional = machine.getTraitHolder().getTrait(RecipeLogic.TYPE);
+      
+      // Gets all traits with the specified type.
+      List<NotifiableItemStackHandler> allItemStackHandlers = machine.getTraitHolder().getTraits(NotifiableItemStackHandler.TYPE);
+      
+  }
+}
+```
+
+### Removed interfaces
+
+A large number of machine feature interfaces have been removed, and have had their functionality merged into the standard MetaMachine class, or now use the new machine trait system:
+
+- `ITurbineMachine` Use the `LargeTurbineMachine` class directly.
+- `IRotorHolderMachine` Use the `RotorHolderMachine` class directly.
+- `IMultiController` Use the `MultiblockControllerMachine` class directly.
+- `IMufflerMachine` Use the `MufflerMachine` class directly.
+- `IMachineLife` Override the `MetaMachine::onMachinePlaced` and `MetaMachine::onMachineDestroyed`.
+- `IMachineModifyDrops` Override `MetaMachine::modifyDrops`.
+- `IInteractedMachine` Override `MetaMachine::onUse` and `MetaMachine::onLeftClick`.
+- `ICleanroomReceiver` & `ICleanroomProvider` - Use `CleanroomReceiverTrait` and `CleanroomProviderTrait`.
+- `IAutoOutputBoth`, `IAutoOutputFluid`, `IAutoOutputItem` - Use `AutoOutputTrait`.
+- `IExplosionMachine` - Use `EnvironmentalExplosionTrait`, `GTUtil::doExplosion`, and `GTUtil::setOnFire`
+- `IEnvironmentalHazardCleaner` Use `EnvironmentalHazardCleanerTrait`
+- `ILocalizedHazardEmitter` - Use `LocalizedHazardEmitterTrait`
+- `IExhaustVentMachine` - Use `ExhaustVentMachineTrait`
+- `IHPCAComponentHatch` - Use `HPCAComponentTrait`
+- `IHPCAComputationProvider` - Use `HPCAComputationProviderTrait`
+- `IHPCACoolantProvider` - Use `HPCACoolantProviderTrait`
