### 5.1.2. `build/`

This directory contains user configuration files and the output generated by the OpenEmbedded build system in its standard configuration where the source tree is combined with the output. The Build Directory is created initially when you `source` the OpenEmbedded build environment setup script `oe-init-build-env`.

It is also possible to place output and configuration files in a directory separate from the Source Directory by providing a directory name when you `source` the setup script. For information on separating output from your local Source Directory files, see oe-init-build-env.
