# Vectors
### Actively Managed Index Portfolios
Vectors are actively managed Teragon Indices.
They are groups of assets that have common ground with each other. Major Layer 1 blockchains grouped into an index may include BTC, ETH, AVAX, FTM, MATIC, for example.
The exact breakdown of their contributions towards the total index is based on things like marketcap and TVL.
They are a foundational layer of the Teragon Protocol

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://teragon.gitbook.io/teragon/teragons-three-pillars/vectors.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
