+# Kibana / Buildkite
+
+## Directory Structure
+
+- `hooks` - special directory used by Buildkite agents for [hooks](https://buildkite.com/docs/agent/v3/hooks)
+- `pipelines` - contains pipeline definitions
+- `scripts/common` - scripts that get `source`d by other scripts to set environment variables or import shared functions
+- `scripts/lifecycle` - general scripts for tasks that run before or after individual steps or the entire build
+- `scripts/steps` - scripts that define something that will run for a step defined in a pipeline
+- `scripts/*` - all other scripts are building blocks that make up the tasks in pipelines. They may be run by other scripts, but should not be `source`d
