+# Preliminary
+
+## Preliminary Financial Time Series Dataset
+
+> ⚠️ **Warning:** This dataset is preliminary and intended for development, testing, and feedback purposes only.  
+> A stable, production-ready version will be released later as a separate dataset.
+
+## Overview
+
+This dataset contains **parquet files** with time series data for various financial instruments, collected through an early-stage version of our data pipeline. The data is already usable, but the structure and naming conventions are **still subject to change**.
+
+Each instrument currently has:
+- One file with **daily candles** covering multiple years
+- One file with **minute candles** covering a much shorter, but more detailed recent period
+
+This dual-resolution format is intended to enable models that can reason across both long-term and short-term patterns.
+
+## Purpose
+
+This preliminary dataset exists to:
+- Make early access to usable data possible
+- Facilitate testing and iteration
+- Gather feedback before finalizing a stable format
+
+## Expected Changes
+
+The internal structure of the parquet files will remain stable. However, the following may change:
+- File naming conventions
+- Organization into folders or shards (e.g., by year or month)
+- Dataset split logic
+
+The final version will be released separately to ensure compatibility and stability for users who rely on long-term consistency.
+
+### License & Usage
+
+This dataset is not licensed under a standard open data license.
+
+See the `LICENSE` file for usage permissions. The dataset is intended for **solely for research and educational purposes**.  
+Data is aggregated from publicly available sources such as [Yahoo Finance](https://finance.yahoo.com) via `yfinance`.
+
+Redistribution may be restricted. Please respect the terms of the original data providers.
