	### Dataset Summary

	The Multi_Legal_Pile is a large-scale multilingual legal dataset suited for pretraining language models.
	It spans over 24 languages and five legal text types.

	### Supported Tasks and Leaderboards

	The dataset supports the tasks of fill-mask.

	### Languages

	The following languages are supported: bg, cs, da, de, el, en, es, et, fi, fr, ga, hr, hu, it, lt, lv, mt, nl, pl, pt,
	ro, sk, sl, sv

	## Dataset Structure

	It is structured in the following format:
	type -> language -> jurisdiction.jsonl.xz

	type is one of the following:

	- caselaw
	- contracts
	- legislation
	- other
	- legal_mc4

	`legal_mc4` is a subset of the other type but is listed separately so it can be easily excluded since it is less
	permissively licensed than the other types.

	Use the dataset like this:

	```python
	from datasets import load_dataset

	config = 'en_contracts' # {language}_{type}
	dataset = load_dataset('joelito/Multi_Legal_Pile', config, split='train', streaming=True)
	```

	'config' is a combination of language and text_type, e.g. 'en_contracts' or 'de_caselaw'.
	To load all the languages or all the text_types, use 'all' instead of the language or text_type (e.g., '
	all_legislation').

	### Data Instances

	The file format is jsonl.xz and there is one split available ("train").

	The complete dataset (689GB) consists of four large subsets:

	- Native Multi Legal Pile (112GB)
	- Eurlex Resources (179GB)
	- Legal MC4 (106GB)
	- Pile of Law (292GB)
