Fix paper link, add project page and sample usage

This PR improves the model card of EvoEmbedding by:
- Fixing the broken/empty paper link and linking it to the arXiv paper.
- Adding the official project page link.
- Adding a "Quick Start" section with sample usage code snippets demonstrating how to use the model as an embedding model and as a reranker, as described in the official GitHub repository.

 **EvoEmbedding** is a novel embedding model designed for long-context and dynamic retrieval scenarios. Unlike static embedding models that chunk text in isolation, EvoEmbedding maintains a continuously updated **Latent Memory Queue**. This allows it to capture temporal dynamics and generate *context-aware, evolvable embeddings* for precise retrieval in agentic workflows and long-conversations.
 
+## 🚀 Quick Start
+
+To use EvoEmbedding, please clone the [GitHub Repository](https://github.com/MiG-NJU/EvoEmbedding) and install the environment.
+
+### As an Embedding Model
+
+```python
+from model.client import EvoEmbeddingClient
+
+client = EvoEmbeddingClient()
+
+messages = [
+    {"role": "user", "content": "I visited Paris in April."},
+    {"role": "assistant", "content": "Noted."},
+    {"role": "user", "content": "I bought a new laptop yesterday."},
+    {"role": "assistant", "content": "Got it."},
+    {"role": "user", "content": "Where did I travel in spring?"},
+]
+
+embeddings = client.encode_messages(messages)
+```
+
+The `messages` input preserves the original dialogue order. `encode_messages` returns normalized embeddings for the history turns and the final query.
+
+### As a Reranker
+
+```python
+candidates = [
+    "I visited Paris in April.",
+    "I bought a new laptop yesterday.",
+    "The meeting was moved to Friday.",
+]
+query = "Where did I travel in spring?"
+
+ranked_candidates, ranked_indices = client.rerank(
+    query,
+    candidates,
+    top_k=1,
+    return_indices=True,
+)
+```
+
+The reranker takes a direct list of candidate strings and returns them in relevance order.
