 Python library for Synthetic Data Generation
+
+## Introduction
+
+Synthetic Data Generation (SDG) is a process that creates an artificially generated dataset that mimics real data based on provided examples. SDG uses a YAML file containing question-and-answer pairs as input data.
+
+## Installing the SDG library
+
+Clone the library and navigate to the repo:
+
+```bash
+git clone https://github.com/instructlab/sdg
+cd sdg
+```
+
+Install the library:
+
+```bash
+pip install .
+```
+
+### Using the library
+
+You can import SDG into your Python files with the following items:
+
+```python
+ from instructlab.sdg.generate_data import generate_data
+ from instructlab.sdg.utils import GenerateException
+```
+
+## Pipelines
+
+There are four pipelines that are used in SDG. Each pipeline requires specific hardware specifications.
+<!--TODO: Add explanations of pipelines-->
+
+*Full* -
+
+This pipeline is targeted for running SDG on consumer grade accelerators (GPUs).
+
+*Simple* -
+
+This pipeline is targeted for running SDG on CPUs.
+
+### Pipeline architecture
+
+All the pipelines are written in YAML format.
