+This repository contains the models used in the gr-nlp-toolkit project (https://github.com/nlpaueb/gr-nlp-toolkit).
+-
+The toolkit includes the following models, all designed specifically for processing the Greek language:
+- Named Entity Recognition (NER): Identifies and classifies named entities in Greek text,
+  such as names of people, organizations, and locations.
+- Dependency Parsing (DP): Analyzes the grammatical structure of Greek sentences by identifying relationships between words and their dependencies.
+- Part Of Speech tagging (POS): Tags each word in Greek text with its corresponding part of speech (e.g., noun, verb, adjective), along with its morphological features.
 
+**Note:**
+  These models cannot be used as standalone tools; they are integrated into the gr-nlp-toolkit and can only be utilized through it.
