# Buildkite Monorepo Documentation

> Buildkite documentation for building and managing monorepo CI/CD pipelines, including change detection, dynamic pipelines, and best practices.

## Pipelines

### Best practices

- [Working with monorepos](https://buildkite.com/docs/pipelines/best-practices/working-with-monorepos.md): Static and dynamic approaches for running monorepo pipelines with change detection using if_changed and diff plugins.

### Tutorials

- [Dynamic pipelines and annotations using Bazel](https://buildkite.com/docs/pipelines/tutorials/dynamic-pipelines-and-annotations-using-bazel.md): Tutorial for creating dynamic pipelines and build annotations using Bazel with a monorepo example project.

### Configure pipelines

#### Step types

- [Trigger step](https://buildkite.com/docs/pipelines/configure/step-types/trigger-step.md): Reference for trigger steps that create builds on other pipelines, with permissions, async mode, and attribute details.

#### Dynamic pipelines

- [Overview](https://buildkite.com/docs/pipelines/configure/dynamic-pipelines.md): Generating pipeline steps at runtime using scripts that output YAML/JSON and pipe to buildkite-agent pipeline upload.
- [Using if_changed](https://buildkite.com/docs/pipelines/configure/dynamic-pipelines/if-changed.md): Using the if_changed step attribute to skip steps based on Git diff file changes, with glob patterns, monorepo workflows, and comparison strategies.
- [Buildkite SDK](https://buildkite.com/docs/pipelines/configure/dynamic-pipelines/sdk.md): Multi-language SDK (JS, Python, Go, Ruby, C#) for programmatically generating dynamic pipeline steps.
- [Using conditionals](https://buildkite.com/docs/pipelines/configure/conditionals.md): Using if/unless expressions with C-like syntax to conditionally run steps or filter pipeline builds from webhooks.
- [Glob pattern syntax](https://buildkite.com/docs/pipelines/configure/glob-pattern-syntax.md): Syntax reference for glob patterns used in artifact uploads and if_changed step conditions.
