+The CA-DE Parallel Corpus is a Catalan-German dataset of **9.530.709** parallel sentences. The dataset was created to support Catalan in NLP tasks, specifically 
 Machine Translation.
 
 ### Supported Tasks and Leaderboards
 
-The dataset can be used to train a model for Multilingual Machine Translation. Success on this task is typically measured by achieving a high BLEU score.
+The dataset can be used to train Bilingual Machine Translation models between German and Catalan in any direction, 
+as well as Multilingual Machine Translation models.
 
 ### Languages
 
-The texts in the dataset are in Catalan and German.
+The sentences included in the dataset are in Catalan (CA) and German (DE).

 ### Social Impact of Dataset
 
-The purpose of this dataset is to help develop Machine Translation tasks for mid-resource languages such as Catalan.
+By providing this resource, we intend to promote the use of Catalan across NLP tasks, thereby improving the accessibility and visibility of the Catalan language.
 
 ### Discussion of Biases
 
-We are aware that since part of the data comes from unreliable web pages and non-curated texts, some biases may be present in the dataset.
-Nonetheless, we have not applied any steps to reduce their impact.
+No specific bias mitigation strategies were applied to this dataset.
