+## Glossary
+
+- **Woodpecker**: An open-source tool that executes pipelines on your code.
+- **Pipeline**: A sequence of workflows that are executed on the code. Pipelines are triggered by events.
+- **Workflow**: A sequence of steps and services that are executed as part of a pipeline. Workflows are represented by YAML files. Each workflow has its own isolated network.
+- **Steps**: Individual commands, actions or tasks within a workflow.
+- **Code**: Refers to the files tracked by the version control system used by the forge.
+- **Repos**: Short for repositories, these are storage locations where code is stored.
+- **Forge**: The hosting platform or service where the repositories are hosted.
+- **Workspace**: A separate environment or area where a workflow is executed in isolation.
+- **Event**: Triggers the execution of a pipeline, such as a forge event, manual interaction in the user interface, cron job, or command-line interface.
+- **Commit**: A defined state of the code, usually associated with a version control system like Git.
+- **Matrix**: A configuration option that allows the execution of workflows for each value in the matrix.
+- **Service**: A service is a step that is executed from the start of a workflow until its end. It can be accessed by name via the network from other steps within the same workflow.
+- **Plugins**: Plugins are extensions that provide pre-defined actions or commands for a step in a workflow. They can be configured via settings.
+- **Container**: A lightweight and isolated environment where commands are executed in.
+- **YAML File**: A file format used to define and configure workflows.
+- **Dependency**: Workflows can depend on each other, and if possible, they are executed in parallel.
+- **Status**: Status refers to the outcome of a step or workflow after it has been executed, determined by the internal command exit code.
+
+## Terms
+
+Sometimes there exist multiple terms that can be used for a thing, we try to define it here once and stick to it.
+
+- env var `*_LINK` should be `*_URL` also in code, use `URL()` instead of `Link` [[Vote](https://framadate.org/jVSQHwIGfJYy82IL)]
+- Builds are Pipelines
+- In old code there were `Jobs` witch revere to `Steps`
