1. Install the LlamaIndex library using pip.
2. Import necessary components and choose a data connector for your source.
3. Create an index, ingest your data, and then use a query engine to ask questions.

Use a SynaBot assistant to produce the thinking, then move the output into LlamaIndex for execution. Every SynaBot assistant is free to try on the Lite plan.

• Content Creator (ZARA) — drafts the copy, captions and campaign angles you'll run through LlamaIndex.
• Business Planner (VIKRAM) — decides whether LlamaIndex belongs in your stack and what it should replace.
• Project Manager (PACE) — turns the rollout of LlamaIndex into owned, dated tasks.
