# About Configuring DocsFab

> Choose a guide for changing the model, selecting an installed composition, or connecting a local NIM.

DocsFab model configuration binds the provider, model ID, API, endpoint, and credential used by model-backed commands. Complete [installation and setup](/docsfab/get-started/installation#set-up-docsfab) before choosing a configuration task.

## Models and Routes

Choose the task that matches the change you need:

| Task | Guide |
| --- | --- |
| Change the provider, model, API, or endpoint. | [Configure the Model](/docsfab/configure/model) |
| Select a model and endpoint from the installed registry. | [Select an Installed Composition](/docsfab/configure/installed-compositions) |
| Change model settings for one run or future runs. | [Override Model Settings](/docsfab/configure/override-model-settings) |
| Connect a local NVIDIA NIM container. | [Use a Local NIM](/docsfab/configure/local-nim) |
| Measure an exact serving route before drafting a record. | [Probe a Model Route](/docsfab/configure/probe-model-route) |
| Prepare a registry change from a measured verdict. | [Draft a Composition Record](/docsfab/configure/draft-composition) |

Setup validates local configuration without making a model request. A live probe sends requests only with `--live`.

## Output and Private Storage

To declare host paths that can appear in output, follow [Configure Public Output Roots](/docsfab/configure/public-output-roots). To locate saved configuration or replace a key, follow [Manage Local Configuration and Credentials](/docsfab/manage/local-configuration).
