# Explanation These documents explain the design decisions behind cogpy. They help you understand *why* the library works the way it does, not *how* to use it (see {doc}`/tutorials/index` and {doc}`/howto/index` for that). For formal specifications and schema definitions, see {doc}`/reference/index`. ```{toctree} :maxdepth: 1 architecture data-model spectral-conventions detection-framework preprocessing-pipeline primitives package-map preprocess/channel_feature plot/ieeg-toolkit plot/topomap ```
