Every device sensor has a corresponding config section in `config.yaml`, these sections follow a similar structure and we'll use `PHONE_ACCELEROMETER` as an example to explain this structure.
- We recommend reading this page if you are using RAPIDS for the first time
- All computed sensor features are stored under `/data/processed/features` on files per sensor, per participant and per study (all participants).
- Every time you change any sensor parameters, provider parameters or provider features, all the necessary files will be updated as soon as you execute RAPIDS.
- In short, to extract features offered by a provider, you need to set its `[COMPUTE]` flag to `TRUE`, configure any of its parameters, and [execute](../../setup/execution) RAPIDS.
