+### Full Model Architecture
+
+```
+SentenceTransformer(
+  (0): Transformer({'transformer_task': 'feature-extraction', 'modality_config': {'text': {'method': 'forward', 'method_output_name': 'last_hidden_state'}}, 'module_output_name': 'token_embeddings', 'architecture': 'MPNetModel'})

+```
+
+## Usage
+
+### Direct Usage (Sentence Transformers)
+
+First install the Sentence Transformers library:
+
+```bash
+pip install -U sentence-transformers
+```
+Then you can load this model and run inference.
+```python
+from sentence_transformers import SentenceTransformer
+
+# Download from the 🤗 Hub
+model = SentenceTransformer("razsarusi/plottwist-embedder-ft")
+# Run inference
+sentences = [
+    'Boy discovers treasure map in attic, embarks on grand adventure to find lost kingdoms.',
+    "A boy finds an ancient map to a legendary kingdom hidden in his grandfather's attic, leading him on a quest to reunite lost treasures.",
+    'Private investigator Leo Stone faces corruption within his own agency when a high-profile murder case spirals out of control.',
+]
+embeddings = model.encode(sentences)
+print(embeddings.shape)
+# [3, 768]
+
+# Get the similarity scores for the embeddings
+similarities = model.similarity(embeddings, embeddings)
+print(similarities)
+# tensor([[ 1.0000,  0.8125, -0.0376],
+#         [ 0.8125,  1.0000, -0.0777],
+#         [-0.0376, -0.0777,  1.0000]])
