### Agent

#### Command-line reference

- [pipeline](https://buildkite.com/docs/agent/cli/reference/pipeline.md): CLI reference for buildkite-agent pipeline upload: dynamically adding or replacing build steps from YAML/JSON.

### Configure pipelines

- [Defining steps](https://buildkite.com/docs/pipelines/configure/defining-steps.md): How to define pipeline steps in YAML, set up webhooks, configure step defaults, and manage pipeline.yml files.

#### 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.
- [Writing build scripts](https://buildkite.com/docs/pipelines/configure/writing-build-scripts.md): Guidelines for writing shell scripts for builds, including Bash options, debugging, and exit status handling.
- [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.
- [Environment variables](https://buildkite.com/docs/pipelines/configure/environment-variables.md): Complete reference of Buildkite environment variables available in build steps, hooks, and plugins.
- [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.
