# nix3-derivation-add(1)

Add a store derivation

**Warning** \
 This program is **experimental** ⟨@docroot@/development/experimental-features.md#xp-feature-nix-command⟩ and its interface is subject to change.

## Name

`nix derivation add` - Add a store derivation

## Synopsis

`nix derivation add` \[*option*…\]

## Description

This command reads from standard input a JSON representation of a store derivation ⟨@docroot@/glossary.md#gloss-store-derivation⟩\\c .

Store derivations are used internally by Nix. They are store paths with extension `.drv` that represent the build-time dependency graph to which a Nix expression evaluates.

`nix derivation add` takes a single derivation in the following format:

{{#include ../../protocols/json/derivation.md}}
