+# Azure DevOps Pipelines Fundamentals
+
+Azure Pipelines automates builds, tests, and deployments with YAML pipelines.
+
+## Core Concepts
+
+- `Pipeline`: End-to-end CI/CD definition.
+- `Stage`: Environment-level boundary.
+- `Job`: Unit running on an agent.
+- `Task`: Built-in operation in a job.
+- `Service Connection`: Secure integration to cloud/tools.
+
+## Best Practices
+
+- Use multi-stage YAML for environment promotion.
+- Protect branches and require PR validation.
+- Use variable groups and key vault integration.
+- Separate infra and application deployment concerns.

+# CircleCI Fundamentals
+
+CircleCI executes pipelines from `.circleci/config.yml`.
+
+## Core Concepts
+
+- `Workflow`: Pipeline orchestration.
+- `Job`: Task bundle with steps.
+- `Executor`: Runtime (Docker, machine, macOS).
+- `Orbs`: Reusable CircleCI packages.
+- `Contexts`: Shared secure environment variables.
+
+## Best Practices
+
+- Reuse commands/executors for consistency.
+- Cache dependencies with stable keys.
+- Keep jobs parallel where possible.
+- Scope contexts by environment and team.
