+# **Pull Requests (PRs)**
+
+We use GitHub labels to categorize PRs. Before a PR can be merged, it must be assigned one of the following **kind/** labels:
+
+- **kind/bugfix** - For PRs that fix bugs.
+- **kind/dependencies** - For PRs that update dependencies or related components.
+- **kind/enhancement** - For PRs that introduce new features or improve existing functionality. This label also applies to improvements in documentation, testing, and similar areas. Any changes must be backward-compatible.
+- **kind/refactor** - For PRs that restructure or remove code without adding new functionality. This label also applies to changes that affect user-facing APIs.
+
+---
+
+# **Issues**
+
+Issues are categorized using the following three **GitHub types** (not GitHub labels):
+
+- **bug** - Reports an unexpected problem or incorrect behavior.
+- **design** - Relates to design considerations or decisions.
+- **enhancement** - Suggests a new feature, improvement, or idea.
+
+To track the lifecycle of issues, we also use GitHub labels:
+
+- **lifecycle/needs-review** - A temporary label indicating that the issue has not yet been reviewed.
+- **lifecycle/confirmed** - Confirms the issue’s validity:
+  - If the issue type is **bug**, the bug has been verified.
+  - If the issue type is **enhancement**, the proposal is considered reasonable but does not guarantee implementation.
+  - This label does not indicate when or if the fix or enhancement will be implemented.
+- **lifecycle/needs-info** - The issue requires additional information from the original poster (OP).
+- **lifecycle/blocked** - The issue is blocked by another issue or external factor.
+
+The following labels should be applied to issues prior to closing, indicating the resolution status of the issue:
+
+- **lifecycle/duplicate** - The issue is a duplicate of another issue.
+- **lifecycle/fixed** - The issue has been resolved.
+- **lifecycle/not-a-bug** - The issue is not considered a bug, and no further action is needed.
+- **lifecycle/wont-fix** - The issue will not be fixed.
+
+In addition to lifecycle labels, we use the following labels to further categorize issues:
+
+- **good-first-issue** - The issue is suitable for new contributors or those looking for a simple task to start with.
+- **help-wanted** - The issue is a request for help or assistance.
+- **question** - The issue is a question or request for information.
+
+---
+
+# **Issues & PRs**
+
+In addition to **kind/*** labels, we use optional **area/*** labels to specify the focus of a PR or issue. These labels are purely for categorization, and are not mandatory.
+
+- **area/API** - Related to the API or public interface.
+- **area/dependencies** - Concerns dependencies or related components. This label is different from **kind/dependencies**, which should only used for PRs.
+- **area/documentation** - Related to documentation updates or improvements.
+- **area/infrastructure** - Concerns infrastructure rather than core functionality.
+- **area/performance** - Addresses performance.
+- **area/security** - Involves security-related changes or fixes.
+- **area/testing** - Related to tests or testing infrastructure.
