+
+### Dataset Summary
+
+Carolina is an Open Corpus for Linguistics and Artificial Intelligence with a
+robust volume of texts of varied typology in contemporary Brazilian Portuguese
+(1970-2021). This corpus contains documents and texts extracted from the web
+and includes information (metadata) about its provenance and tipology.
+
+The documents are clustered into taxonomies and the corpus can be loaded in complete or taxonomy modes. To load a single taxonomy, it is possible to pass a code as a parameter to the loading script (see the example bellow). Codes are 3-letters string and possible values are:
+
+- `dat` : datasets and other corpora;
+- `jud` : judicial branch;
+- `leg` : legislative branch;
+- `pub` : public domain works;
+- `soc` : social media;
+- `uni` : university domains;
+- `wik` : wikis.
+
+**Example:**
+
+```python
+from datasets import load_script
+
+# to load all taxonomies
+corpus_carolina = load_scrip("carolina-c4ai/corpus-carolina")
+
+# to load social media documents
+social_media = load_scrip("carolina-c4ai/corpus-carolina", taxonomy="soc")
+```
+
+### Supported Tasks
+
+Carolina corpus was compiled for academic purposes,
+namely linguistic and computational analysis.
+
+
+### Languages
+
+Contemporary Brazilian Portuguese (1970-2021).
+
+## Dataset Structure
+
+Files are stored inside `corpus` folder with a subfolder
+for each taxonomy. Every file folows a XML structure
+(TEI P5) and contains multiple extracted documents. For
+each document, the text and metadata are exposed as
+`text` and `meta` features, respectively.
+
+### Data Instances
+
+Every instance have the following structure.
+
+```
+{
+    "meta": datasets.Value("string"),
+    "text": datasets.Value("string")
+}
+```
+
+| Code | Taxonomy                   | Instances |  Size  |
+|:----:|:---------------------------|----------:|-------:|
+|      | **Total**                  |   1745187 | 7.3 GB |
+| dat  | Datasets and other Corpora |   1098717 | 3.3 GB |
+| wik  | Wikis                      |    603968 | 2.6 GB |
+| jud  | Judicial Branch            |     38068 | 1.4 GB |
+| leg  | Legislative Branch         |        14 |  20 MB |
+| soc  | Social Media               |      3449 |  15 MB |
+| uni  | University Domains         |       945 | 9.4 MB |
+| pub  | Public Domain Works        |        26 | 3.6 MB |

+
+
+### Data Fields
+
+- `meta`: a XML string with a TEI conformant `teiHeader` tag. It is exposed as text and needs to be parsed in order to access the actual metada;
+- `text`: a string containing the extracted document.
+
+### Data Splits
+
+As a general corpus, Carolina does not have splits. In order to load the dataset, it is used `corpus` as its single split.
+
+
+## Additional Information
+
+
+### Dataset Curators
+
+The Corpus Carolina is developed by a multidisciplinary
+team of linguists and computer scientists, members of the
+Virtual Laboratory of Digital Humanities - LaViHD and the Artificial Intelligence Center of the University of São Paulo - C4AI.
+
+
+### Licensing Information

+compiled for academic purposes, namely linguistic and computational analysis.
+It is composed of texts assembled in various digital repositories, whose
