\n\n```bash\npip install chromadb # python client\n# for javascript, npm install chromadb!\n# for client-server mode, chroma run --path /chroma_db_path\n```\n\n## Chroma Cloud\n\nOur hosted service, Chroma Cloud, powers serverless vector, hybrid, and full-text search. It's extremely fast, cost-effective, scalable and painless. Create a DB and try it out in under 30 seconds with $5 of free credits.\n\n[Get started with Chroma Cloud](https://trychroma.com/signup)\n\n## API\n\nThe core API is only 4 functions (run our [💡 Google Colab](https://colab.research.google.com/drive/1QEzFyqnoFxq7LUGyP1vzR4iLt9PpCDXv?usp=sharing)):\n\n```python\nimport chromadb\n# setup Chroma in-memory, for easy prototyping. Can add persistence easily!\nclient = chromadb.Client()\n\n# Create collection. get_collection, get_or_create_collection, delete_collection also available!\ncollection = client.create_collection(\"all-my-documents\")\n\n# Add docs to the collection. Can also update and delete. Row-based API coming soon!\ncollection.add(\n documents=[\"This is document1\", \"This is document2\"], # we handle tokenization, embedding, and indexing automatically. You can skip that and add your own embeddings as well\n metadatas=[{\"source\": \"notion\"}, {\"source\": \"google-docs\"}], # filter on these!\n ids=[\"doc1\", \"doc2\"], # unique for each doc\n)\n\n# Query/search 2 most similar results. You can also .get by id\nresults = collection.query(\n query_texts=[\"This is a query document\"],\n n_results=2,\n # where={\"metadata_field\": \"is_equal_to_this\"}, # optional filter\n # where_document={\"$contains\":\"search_string\"} # optional filter\n)\n```\n\nLearn about all features on our [Docs](https://docs.trychroma.com)\n\n## Get involved\n\nChroma is a rapidly developing project.
