+## Learn about Prow
+
+[Prow](https://github.com/kubernetes/test-infra/blob/master/prow/README.md) is
+the Kubernetes-based CI/CD system that runs jobs against pull requests (PRs). Prow
+enables chatbot-style commands to handle GitHub actions across the Kubernetes
+organization. You can perform a variety of actions such as [adding and removing
+labels](#add-and-remove-labels), closing issues, and assigning an approver. Type
+the Prow command into a comment field using the `/<command-name>` format. Some common
+commands are:
+
+- `/lgtm` (looks good to me): adds the `lgtm` label, signalling that a reviewer has finished reviewing the PR
+- `/approve`: approves a PR so it can merge (approver use only)
+- `/assign`: assigns a person to review or approve a PR
+- `/close`: closes an issue or PR
+- `/hold`: adds the `do-not-merge/hold` label, indicating the PR cannot be automatically merged
+- `/hold cancel`: removes the `do-not-merge/hold` label
+
+{{% note %}}
+Not all commands are available to every user. The Prow bot will tell you if you
+try to execute a command beyond your authorization level.
+{{% /note %}}
+
+Familiarize yourself with the [list of Prow
+commands](https://prow.k8s.io/command-help) before you review PRs or triage issues.

 ## Triage and categorize issues

 People in SIG Docs are responsible only for triaging and categorizing
 documentation issues. General website issues are also filed in the
 `kubernetes/website` repository.
 
 When you triage an issue, you:

+### Add and remove labels
+
+To add a label, leave a comment like `/<label-to-add>` or `/<label-category> <label-to-add>`. The label must
+already exist. If you try to add a label that does not exist, the command is
+silently ignored.
+
+Examples:
+
+- `/triage needs-information`
+- `/priority important-soon`
+- `/language ja`
+- `/help`
+- `/good-first-issue`
+- `/lifecycle frozen`
+
+To remove a label, leave a comment like `/remove-<label-to-remove>` or `/remove-<label-category> <label-to-remove>`.
+
+Examples:
+
+- `/remove-triage needs-information`
+- `/remove-priority important-soon`
+- `/remove-language ja`
+- `/remove-help`
+- `/remove-good-first-issue`
+- `/remove-lifecycle frozen`
+
+The list of all the labels used across Kubernetes is
+[here](https://github.com/kubernetes/kubernetes/labels). Not all labels
+are used by SIG Docs.
 
 ### More about labels
 
-These guidelines are not set in stone and are subject to change.
-
 - An issue can have multiple labels.
 - Some labels use slash notation for grouping, which can be thought of like
   "sub-labels". For instance, many `sig/` labels exist, such as `sig/cli` and
-  `sig/api-machinery`.
+  `sig/api-machinery` ([full list](https://github.com/kubernetes/website/labels?utf8=%E2%9C%93&q=sig%2F)).
 - Some labels are automatically added based on metadata in the files involved
   in the issue, slash commands used in the comments of the issue, or
   information in the issue text.
-- Some labels are manually added by the person triaging the issue (or the person

-  - `Actionable`: There seems to be enough information for the issue to be fixed
+  - `kind/bug`, `kind/feature`, and `kind/documentation`: A bug is a problem with existing content or
-    or acted upon.
-  - `good first issue`: Someone with limited Kubernetes or SIG Docs experience
-    might be able to tackle this issue.
-  - `kind/bug`, `kind/feature`, and `kind/documentation`: If the person who
-    filed the issue did not fill out the template correctly, these labels may
-    not be assigned automatically. A bug is a problem with existing content or
     functionality, and a feature is a request for new content or functionality.

+### Issue lifecycle
+
+Issues are generally opened and closed within a relatively short time span.
+However, sometimes an issue may not have associated activity after it is
+created. Other times, an issue may need to remain open for longer than 90 days.
+
+`lifecycle/stale`: after 90 days with no activity, an issue is automatically
+labeled as stale. The issue will be automatically closed if the lifecycle is not
+manually reverted using the `/remove-lifecycle stale` command.
+
+`lifecycle/frozen`: an issue with this label will not become stale after 90 days
+of inactivity. A user manually adds this label to issues that need to remain
+open for much longer than 90 days, such as those with a
+`priority/important-longterm` label.
