+## Dataset Description
+
+- **Home:** [Flores](https://github.com/facebookresearch/flores)
+- **Repository:** [Github](https://github.com/facebookresearch/flores)
+
+### Dataset Summary
+
+FLORES is a benchmark dataset for machine translation between English and low-resource languages.
+
+>The creation of FLORES-200 doubles the existing language coverage of FLORES-101. 
+Given the nature of the new languages, which have less standardization and require 
+more specialized professional translations, the verification process became more complex. 
+This required modifications to the translation workflow. FLORES-200 has several languages 
+which were not translated from English. Specifically, several languages were translated 
+from Spanish, French, Russian and Modern Standard Arabic. Moreover, FLORES-200 also 
+includes two script alternatives for four languages. FLORES-200 consists of translations 
+from 842 distinct web articles, totaling 3001 sentences. These sentences are divided 
+into three splits: dev, devtest, and test (hidden). On average, sentences are approximately 
+21 words long.
+
+**Disclaimer**: *The Flores-200 dataset is hosted by the Facebook and licensed under the [Creative Commons Attribution-ShareAlike 4.0 International License](https://creativecommons.org/licenses/by-sa/4.0/).
+### Supported Tasks and Leaderboards
+#### Multilingual Machine Translation
+Refer to the [Dynabench leaderboard](https://dynabench.org/flores/Flores%20MT%20Evaluation%20(FULL)) for additional details on model evaluation on FLORES-101 in the context of the WMT2021 shared task on [Large-Scale Multilingual Machine Translation](http://www.statmt.org/wmt21/large-scale-multilingual-translation-task.html). Flores 200 is an extention of this.
+
+### Languages
+The dataset contains parallel sentences for 200 languages, as mentioned in the original [Github](https://github.com/facebookresearch/flores/blob/master/README.md) page for the project. Languages are identified with the ISO 639-3 code (e.g. `eng`, `fra`, `rus`) plus an additional code describing the script (e.g., "eng_Latn", "ukr_Cyrl"). See [the webpage for code descriptions](https://github.com/facebookresearch/flores/blob/main/flores200/README.md).
+
+Use the configuration `all` to access the full set of parallel sentences for all the available languages in a single command. 
+
+Use a hyphenated pairing to get two langauges in one datapoint (e.g., "eng_Latn-ukr_Cyrl" will provide sentences in the format below).
+
+## Dataset Structure
+### Data Instances
+A sample from the `dev` split for the Ukrainian language (`ukr_Cyrl` config) is provided below. All configurations have the same structure, and all sentences are aligned across configurations and splits.
+```python
+{
+	'id': 1,
+	'sentence': 'У понеділок, науковці зі Школи медицини Стенфордського університету оголосили про винайдення нового діагностичного інструменту, що може сортувати клітини за їх видами: це малесенький друкований чіп, який можна виготовити за допомогою стандартних променевих принтерів десь по одному центу США за штуку.',
+	'URL': 'https://en.wikinews.org/wiki/Scientists_say_new_medical_diagnostic_chip_can_sort_cells_anywhere_with_an_inkjet',
+	'domain': 'wikinews',
+	'topic': 'health',
+	'has_image': 0,
+	'has_hyperlink': 0
+}
+```
+When using a hyphenated pairing or using the `all` function, data will be presented as follows:
+
+```python
+{
+    'id': 1, 
+    'URL': 'https://en.wikinews.org/wiki/Scientists_say_new_medical_diagnostic_chip_can_sort_cells_anywhere_with_an_inkjet', 
+    'domain': 'wikinews', 
+    'topic': 'health', 
+    'has_image': 0, 
+    'has_hyperlink': 0, 
+    'sentence_eng_Latn': 'On Monday, scientists from the Stanford University School of Medicine announced the invention of a new diagnostic tool that can sort cells by type: a tiny printable chip that can be manufactured using standard inkjet printers for possibly about one U.S. cent each.', 
+    'sentence_ukr_Cyrl': 'У понеділок, науковці зі Школи медицини Стенфордського університету оголосили про винайдення нового діагностичного інструменту, що може сортувати клітини за їх видами: це малесенький друкований чіп, який можна виготовити за допомогою стандартних променевих принтерів десь по одному центу США за штуку.'
+}
+```
+
+
+The text is provided as-in the original dataset, without further preprocessing or tokenization.
+### Data Fields
+- `id`: Row number for the data entry, starting at 1.
+- `sentence`: The full sentence in the specific language (may have _lang for pairings)
+- `URL`: The URL for the English article from which the sentence was extracted.
+- `domain`: The domain of the sentence.
+- `topic`: The topic of the sentence.
+- `has_image`: Whether the  original article contains an image.
+- `has_hyperlink`: Whether the  sentence contains a hyperlink.
+### Data Splits
+|            config| `dev`| `devtest`|
