# Bottlerocket Out of Tree Builds
---
### What is it?
* Enable the experience of easily customizing your own Bottlerocket Build
* Maintain a separate repo with only your changes, plus some config files
**Issue**: "Enable out-of-tree Bottlerocket Variants"
https://github.com/bottlerocket-os/bottlerocket/issues/2669
---
### Goals:
* Simple to reason about updating to latest upstream Bottlerocket code
* Ability to add customize packages and supported settings
---
### New Build Tool
* Currently called `sodapop`
* Tooling for managing "out-of-tree" variants
* Allows adding custom packages
* Handles dependency interaction with Bottlerocket SDK and Core image
* Performs image builds
---
### Modular Settings
* Settings will be owned by settings "handlers"
* Handlers are binaries on the filesystem
* Handlers implement migrations, rendering configuration templates, etc for the settings that they own
