+# Ingest to Parquet
+
+Please see the set of
+[transform project conventions](../../../README.md)
+for details on general project conventions, transform configuration,
+testing and IDE set up.
+
+## Summary
+This module is designed to convert raw data files, particularly ZIP files, into Parquet format.Each file contained within the ZIP is transformed into a distinct row within the Parquet dataset, adhering to the below schema.
+
+**title:** (string)
+
+- **Description:** Path to the file within the ZIP archive.
+- **Example:** `"title": "data/file.txt"`
+
+**document:** (string)
+
+- **Description:** Name of the ZIP file containing the current file.
+- **Example:** `"document": "example.zip"`
+
+**contents:** (string)
+
+- **Description:** Content of the file, converted to a string.
+- **Example:** `"contents": "This is the content of the file."`
+
+**document_id:** (string)
+
+- **Description:** Unique identifier generated for each file.
+- **Example:** `"document_id": "b1e4a879-41c5-4a6d-a4a8-0d7a53ec7e8f"`
+
+**ext:** (string)
+
+- **Description:** File extension extracted from the file path.
+- **Example:** `"ext": ".txt"`
+
+**hash:** (string)
+
+- **Description:** sha256 hash value computed from the file content string.
+- **Example:** `"hash": "a1b2c3d4"`
+
+**size:** (int64)
+
+- **Description:** Size of the file content in bytes.
+- **Example:** `"size": 1024`
+
+**date_acquired:** (string)
+
+- **Description:** Timestamp indicating when the file was processed.
+- **Example:** `"date_acquired": "2024-03-25T12:00:00"`
+
+**snapshot:** (string)(optional)
+
+- **Description:** Name indicating which dataset it belong to.
+- **Example:** `"snapshot": "github"`
+
+**programming_language:** (string)(optional)
+
+- **Description:** Programming language detected using the file extension.
+- **Example:** `"programming_language": "Java"`
+
+**domain:** (string)(optional)
+
+- **Description:** Name indicating which domain it belong to, whether code, natural language etc..
+- **Example:** `"domain": "code"`
+
+## Running
+
+### Launched Command Line Options 
+When running the transform with the Ray launcher (i.e. TransformLauncher),
+the following command line arguments are available in addition to 
+the options provided by the [ray launcher](../../../../data-processing-lib/doc/ray-launcher-options.md)
+and the [python launcher](../../../../data-processing-lib/doc/python-launcher-options.md).
+
+```
+  --ingest_detect_programming_lang_key 
+                        generate programming language from the file extension
+  --ingest_snapshot_key 
+                        Name the dataset
+  --ingest_domain_key 
+                        To identify whether data is code or natural language
+  --ingest_supported_langs_file_key
+                        Specify the path to the JSON file that maps programming languages to their respective file extensions. In this file, each key represents a programming language, and the corresponding value is a list of its extensions. You can find the file at ray/test-data/languages/lang_extensions.json for reference.
+
+```
+
+### Running the samples
+To run the samples, use the following `make` targets
+
+* `run-cli-ray-sample` - runs src/ingest_2_parquet_transform_ray.py using command line args
+* `run-local-sample` - runs src/ingest_2_parquet_local.py
+* `run-local-ray-sample` - runs src/ingest_2_parquet_local_ray.py
+* `run-s3-ray-sample`- runs src/ingest_2_parquet_s3_ray.py
+
+These targets will activate the virtual environment and set up any configuration needed.
+Use the `-n` option of `make` to see the detail of what is done to run the sample.
+
+For example, 
+```shell
+make run-cli-ray-sample
+...
+```
+Then 
+```shell
+ls output
+```
+To see results of the transform.
