-Data Prep Lab is a cloud native [Ray](https://docs.ray.io/en/latest/index.html)
-based toolkit that allows a user to quickly prepare their data for building LLM applications using a set of available transforms.
-This toolkit gives the user flexibility to run data prep from laptop-scale to cluster-scale, 
-and provides automation via [KFP pipelines](https://www.kubeflow.org/docs/components/pipelines/v1/introduction/). Moreover, a user can add in their own data prep module and scale it 
-using Ray without having to worry about Ray internals. 
+Data Prep Lab is community project to democratize and accelerate unstructured data preparation for LLM app developers. 
+With the explosive growth of LLM-enabled use cases, developers are faced with the enormous challenge of preparing use case specific unstructured data to fine-tune or instruct-tune the LLMs.
+As the variety of use cases grows, so does the need to support:
+- New modalities of data (code, language, speech, visual) 
+- New ways of transforming the data to optimize the performance of the resulting LLMs for each specific use case.
+- Large variety in the scale of data to be processed, laptop-scale to datacenter-scale
+
+Data Prep Lab offers implementations of commonly needed data transformations, called *modules*, for both Code and Language modalities.
+The goal is to offer high-level APIs for developers to quickly get started in working with their data, without needing expertise in the underlying runtimes and frameworks.

+Data Prep Lab is a toolkit for streamlining data preparation for developers looking to build LLM-enabled applications via fine-tuning or instruction-tuning.
+Data Prep Lab contributes a set of modules that the developer can get started with to easily build data pipelines suitable for their use case.
+These modules have been tested in producing pre-training datasets for the [Granite](https://huggingface.co/instructlab/granite-7b-lab) open models. 
 
-Data Prep LAB is an toolkit that enables users to prepare their data for building LLM applications.
-This toolkit comes with a set of available modules (known as transforms) that the user can get started 
-with to easily build customized data pipelines.
-This set of transforms is built on a framework, known as the data processing library, 
-that allows a user to quickly build in their own new transforms and then scale them as needed.
-Users can incorporate their logic for custom data transformation and then use the included Ray-based
-distributed computing framework to scalably apply the transform to their data. 
+The modules are built on common frameworks (for Spark and Ray), called the *data processing library* that allows the developers to build new custom modules that readily scale across a variety of runtimes.
+Eventually, Data Prep Lab will offer consistent APIs and configurations across the following underlying runtimes.
+1. Python runtime
+2. Ray runtime (local and distributed)
+3. Spark runtime (local and distributed)
+4. [No-code pipelines with KFP](https://www.kubeflow.org/docs/components/pipelines/v1/introduction/) (local and distributed, wrapping Ray)
+
+Current matrix for the combination of modules and supported runtimes is shown in the table below. 
+Contributors are welcome to add new modules as well as add runtime support for existing modules!

 #### Transform design: 
-A transform can follow one of the two patterns: filter or annotator pattern.
-In the annotator design pattern, a transform adds information during the processing by adding one more column to the parquet file.

+- **Annotator** An anotator transform adds information during the processing by adding one more column to the parquet file.
 The annotator design also allows a user to verify the results of the processing before actual filtering of the data.
-When a transform acts as a filter, it processes the data and outputs the transformed data (example exact deduplication).

 #### Scaling of transforms: 
-The distributed infrastructure, based on [Ray](https://docs.ray.io/en/latest/index.html), is used to scale out the transformation process.
+To enable processing large volumes of data leveraging multi-mode clusters, [Ray](https://docs.ray.io/en/latest/index.html) and [Spark](https://spark.apache.org) wrappers are provided, to readily scale-out the Python implementations.
