+# Planning Evaluator
+
+## Purpose
+
+This package provides a node to convert `diagnostic_msgs::msg::DiagnosticArray` messages
+into `tier4_simulation_msgs::msg::UserDefinedValue` messages.
+
+## Inner-workings / Algorithms
+
+The node subscribes to all topics listed in the parameters and assumes they publish
+`DiagnosticArray` messages.
+Each time such message is received,
+it is converted into as many `UserDefinedValue` messages as the number of `KeyValue` objects.
+The format of the output topic is detailed in the _output_ section.
+
+## Inputs / Outputs
+
+### Inputs
+
+The node listens to `DiagnosticArray` messages on the topics specified in the parameters.
+
+### Outputs
+
+The node outputs `UserDefinedValue` messages that are converted from the received `DiagnosticArray`.
+
+The name of the output topics are generated from the corresponding input topic, the name of the diagnostic status, and the key of the diagnostic.
+For example, we might listen to topic `/diagnostic_topic` and receive a `DiagnosticArray` with 2 status:
+
+- Status with `name: "x"`.
+  - Key: `a`.
+  - Key: `b`.
+- Status with `name: "y"`.
+  - Key: `a`.
+  - Key: `c`.
+
+The resulting topics to publish the `UserDefinedValue` are as follows:
+
+- `/metrics_x_a`.
+- `/metrics_x_b`.
+- `/metrics_y_a`.
+- `/metrics_y_c`.
+
+## Parameters
+
+| Name                | Type             | Description                                                   |
+| :------------------ | :--------------- | :------------------------------------------------------------ |
+| `diagnostic_topics` | list of `string` | list of DiagnosticArray topics to convert to UserDefinedValue |
+
+## Assumptions / Known limits
+
+Values in the `KeyValue` objects of a `DiagnosticStatus` are assumed to be of type `double`.
+
+## Future extensions / Unimplemented parts
