+
+## 🚀 Quick Start
+
+### Installation
+
+```bash
+pip install transformers torch
+```
+
+### Usage
+
+```python
+from transformers import pipeline
+
+# Load the model and tokenizer
+# Model: https://huggingface.co/OpenMed/OpenMed-NER-PharmaDetect-MultiMed-335M
+model_name = "OpenMed/OpenMed-NER-PharmaDetect-MultiMed-335M"
+
+# Create a pipeline
+medical_ner_pipeline = pipeline(
+    model=model_name,
+    aggregation_strategy="simple"
+)
+
+# Example usage
+text = "Administration of metformin reduced glucose levels significantly."
+entities = medical_ner_pipeline(text)
+
+print(entities)
+
+token = entities[0]
+print(text[token["start"] : token["end"]])
+```
+
+NOTE: The `aggregation_strategy` parameter defines how token predictions are grouped into entities. For a detailed explanation, please refer to the [Hugging Face documentation](https://huggingface.co/docs/transformers/en/main_classes/pipelines#transformers.TokenClassificationPipeline.aggregation_strategy).
+
+Here is a summary of the available strategies:
+- **`none`**: Returns raw token predictions without any aggregation.
+- **`simple`**: Groups adjacent tokens with the same entity type (e.g., `B-LOC` followed by `I-LOC`).
+- **`first`**: For word-based models, if tokens within a word have different entity tags, the tag of the first token is assigned to the entire word.
+- **`average`**: For word-based models, this strategy averages the scores of tokens within a word and applies the label with the highest resulting score.
+- **`max`**: For word-based models, the entity label from the token with the highest score within a word is assigned to the entire word.
+
+### Batch Processing
+
+For efficient processing of large datasets, use proper batching with the `batch_size` parameter:
+
+```python
+texts = [
+    "Administration of metformin reduced glucose levels significantly.",
+    "The study evaluated the efficacy of cisplatin in cancer treatment.",
+    "Patients received ibuprofen for inflammation management.",
+    "The patient's medication was switched to tamoxifen to prevent breast cancer recurrence.",
+    "Lithium carbonate is often prescribed for the management of bipolar disorder.",
+]
+
+# Efficient batch processing with optimized batch size
+# Adjust batch_size based on your GPU memory (typically 8, 16, 32, or 64)
+results = medical_ner_pipeline(texts, batch_size=8)
+
+for i, entities in enumerate(results):
+    print(f"Text {i+1} entities:")
+    for entity in entities:
+        print(f"  - {entity['word']} ({entity['entity_group']}): {entity['score']:.4f}")
+```
+
+### Large Dataset Processing
+
+For processing large datasets efficiently:
+
+```python
+from transformers.pipelines.pt_utils import KeyDataset
+from datasets import Dataset
+import pandas as pd
+
+# Load your data
+# Load a medical dataset from Hugging Face
+from datasets import load_dataset
+
+# Load a public medical dataset (using a subset for testing)
+medical_dataset = load_dataset("BI55/MedText", split="train[:100]")  # Load first 100 examples
+data = pd.DataFrame({"text": medical_dataset["Completion"]})
+dataset = Dataset.from_pandas(data)
+
+# Process with optimal batching for your hardware
+batch_size = 16  # Tune this based on your GPU memory
+results = []
+
+for out in medical_ner_pipeline(KeyDataset(dataset, "text"), batch_size=batch_size):
+    results.extend(out)
+
+print(f"Processed {len(results)} texts with batching")
+
+```
+
+### Performance Optimization
+
+**Batch Size Guidelines:**
+- **CPU**: Start with batch_size=1-4
+- **Single GPU**: Try batch_size=8-32 depending on GPU memory
+- **High-end GPU**: Can handle batch_size=64 or higher
+- **Monitor GPU utilization** to find the optimal batch size for your hardware
+
+**Memory Considerations:**
+```python
+# For limited GPU memory, use smaller batches
+medical_ner_pipeline = pipeline(
+    model=model_name,
+    aggregation_strategy="simple",
+    device=0  # Specify GPU device
+)
+
+# Process with memory-efficient batching
+for batch_start in range(0, len(texts), batch_size):
+    batch = texts[batch_start:batch_start + batch_size]
+    batch_results = medical_ner_pipeline(batch, batch_size=len(batch))
+    results.extend(batch_results)
+```
