+# Multilingual Dataset Index
+
+A curated list of multilingual text datasets available on Huggingface, designed to help users easily find datasets by language—including those for low-resource languages.
+
+### Purpose
+
+This index aims to make it easier to find datasets by language, addressing the common issue of inconsistent or unclear language codes across different datasets.
+
+### Format
+
+The index is provided as a CSV file with the following columns:
+
+* `language`: The English name of the language, as listed in the dataset configuration.
+* `dataset`: The Huggingface identifier for the dataset.
+* `config`: The specific configuration name within the dataset that corresponds to the language.
+* `language_code`: A language code inferred from the config name, standardized to the ISO 639-3 format.
+
+### Limitations
+
+* Different dialects or varieties of the same language may be listed separately (for example, Arabic, Standard Arabic, Egyptian Arabic, Moroccan Arabic).  
+* Some languages with multiple scripts are grouped under the same language code, such as:  
+  * Hindi in Devanagari script vs. Romanized Hindi (Hinglish)  
+  * Simplified vs. Traditional Chinese  
+* Users should review the configuration names carefully to choose the right variant for their needs.  
+* Automatic language detection may be inaccurate, particularly for low-resource languages. As a result, the actual number of high-quality languages in some datasets may be lower than it appears.  
+* This index includes only multilingual datasets (those that cover more than one language) and does not include datasets focused solely on a single language.
