-- **Node level config**
-
-  We have also introduced the concept of node-level config. This is designed for pluin configuration that might vary between components in the tree. For example, for each child in the tree you might wish to use the `regroup` feature to group the outputs according to a different set of keys.

 - **Defaults**
 
   We have also introduced the concept of `defaults`. This is a section in each component's definition that can be used to provide fallbacks for missing input data. For example, perhaps you have a value arriving from an external API that should be present in every observation in your inputs array, but for soem reason the API fails to deliver a value for some timestamps. In this case, IF would fallback to the value provided for that metric in the `defaults` section of the manifest for that component.

 Technically time-sync is not a new feature as it was present in IF before the refactor, but there are some tweaks to how the plugin is configured that are worth explaining here. Time sync snaps all input arrays across an entire graph to a common time grid.
 
-This means you have to define a global start time, end time and interval to use everywhere. There is also a boolean to toggle whether you should allow the time sync model to pad the start and end of your time series with zeroes. You should default to `true` unless you have a specific reason not to. In the refactored IF we expect this information to be provided in global config, as follows:

 ## Plugins
 
-The plugins themselves require some changes to keep them compatible with the refactored IF.
+Plugins require some modifications to remain compatible with the refactored IF interface.
 
-Instead of the old class-based model, plugins are now functions. They conform to the following interface:
+Each plugin follows the `PluginFactory` interface, which is a higher-order function that accepts a `params` object of type `PluginFactoryParams`. This function returns another function (the inner function), which handles the plugin’s `config`, `parametersMetadata`, and `mapping`.
 
 ```ts
-export type PluginInterface = {
-  execute: (
-    inputs: PluginParams[],
-    config?: Record<string, any>
-  ) => PluginParams[];
-  metadata: {
-    kind: string;
-  };
-  [key: string]: any;
-};
+export const PluginFactory =
+  (params: PluginFactoryParams) =>
+  (
+    config: ConfigParams = {},
+    parametersMetadata: PluginParametersMetadata,
+    mapping: MappingParams
+  ) => ({
+    metadata: {
+      inputs: {...params.metadata.inputs, ...parametersMetadata?.inputs},
+      outputs: parametersMetadata?.outputs || params.metadata.outputs,
+    },
+    execute: async (inputs: PluginParams[]) => {
+      // Generic plugin functionality goes here
+      // E.g., mapping, arithmetic operations, validation
+      // Process inputs and mapping logic
+    });
+  })
 ```
 
-The plugin still requires an execute function. This is where you implement the plugin logic.
+Inner Function Parameters:
+
+- `config`: This is of type `ConfigParams` and has a default value of an empty object ({}). This might hold configuration settings for the plugin.
+- `parametersMetadata`: A `PluginParametersMetadata` object that describes the metadata for the plugin’s parameters.
+- `mapping`: A `MappingParams` object, describing parameters are mapped.

+Implementation Function:
 
-Here's a minimal example for a plugin that sums some inputs defined in global config - see inline comments for some important notes:
+The plugin requires an `implementation` function, where the actual plugin logic is defined.
+Here’s a minimal example of a plugin that sums inputs as defined in the config. See the inline comments for further clarification.
