 ⚛️ **[Components](https://docs.haystack.deepset.ai/v2.0/docs/components):** Each Component achieves one thing. Such as preprocessing documents, retrieving documents, using specific language models to answer questions, and so on. Components can `.connect()` to each other to form a complete pipeline.
 
-🏃‍♀️ **[Pipelines](https://docs.haystack.deepset.ai/v2.0/docs/pipelines):** This is the standard Haystack structure that builds on top of your data to perform various NLP tasks such as retrieval augmented generation, question answering and more. Pipelines in Haystack are Directed Multigraphs composed of components. Components can receive inputs from other components and produce outputs that can be forwarded to other components.

Haystack DocumentStores are available with ElasticSearch, Opensearch, Weaviate, Pinecone, FAISS and more. For a full list of available DocumentStores, check out our [documentation](https://docs.haystack.deepset.ai/docs/document_store).

+## 📏 Telemetry
+
+Haystack collects **anonymous** usage statistics of pipeline components. We receive an event every time these components are initialized. This way, we know which components are most relevant to our community.
