# Beam guides

Working guides and notebooks for Beam, PredictHQ's relevancy engine. Run Beam before configuring features or building forecasts - the `analysis_id` it produces calibrates everything downstream.

Recommended order:

1. [Understanding demand variability and event contribution in Beam](/getting-started/guides/beam-guides/understanding-demand-variability-and-event-contribution-in-beam.md) - how to read what Beam tells you about your demand
2. [ML features by location notebook](https://github.com/predicthq/phq-data-science-docs/blob/master/demand-forecasting-with-events/identify-location-level-features-with-beam-api.ipynb) - from analysis to model-ready features, per location
3. [ML features by group notebook](https://github.com/predicthq/phq-data-science-docs/blob/master/demand-forecasting-with-events/identify-group-level-features-with-beam-api.ipynb) - one consistent feature set across many locations sharing a model
4. [Sample demand data](/getting-started/guides/beam-guides/sample-demand-data.md) - the demand data format Beam expects

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.predicthq.com/getting-started/guides/beam-guides.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
