+# How to use
+
+## Intro
+
+The `@PLUGIN@` plugin allows defining owners (individual accounts or groups)
+of directories, sub-directories and files that require approval when changes
+modify them.
+
+The rules defining which user/group needs to approve which file are specified
+in the `OWNERS` file and are covered in the
+[@PLUGIN@ configuration](config.html) guide.
+
+## Context
+
+The owners plugin can be used in three different modes:
+1. Prolog rules only(deprecated since Gerrit 3.6).
+2. With plugin-provided submit requirements.
+3. With user defined custom submit requirements.
+
+When using the plugin in mode 1. the functionality is limited to the generation
+of a Prolog-based submit rule with no extra UI features.
+
+On top of providing significantly better and more predictable performances,
+using the plugin in either mode 2. or 3. provides extra capabilities like:
+- A REST-api that exposes the owners approval status with single file granularity.
+- Enhanced UI experience with much clearer explanation of who owns what files,
+  as explained below.
+
+## <a id="ownerStatus">Owner status on change page
+
+### <a id="ownerStatus.submitRequirements">Owners status for submit requirements
+
+When either `has:approval_owners` predicate is used in a submit requirement or
+[enableSubmitRequirement](config.html#owners.enableSubmitRequirement) is enabled for a
+project or any of its parents and, if applicable, owners status is displayed in two ways:
+
+* As an icon prepending the submit requirement and as a text next to it
+\
+![submit requirement](./submit-requirement.png "Submit requirement")
+
+Which then displays more detail information in a tooltip when hovered over.
+
+![submit requirement hover](./submit-requirement-hover.png "Submit requirement hover")
+
+* Next to all owned files, even if they are owned by someone else, (when the
+newest patchset is selected)
+\
+![files owners status](./files-owners-status.png "Files owners status")
+
+#### <a id="ownersStatus.submitRequirement.files">Per file owners statuses
+
+The @PLUGIN@ plugin also shows the owners statuses per file in the file list.
+For each file, the owners status is shown as an icon. One can **hover over
+the icon** to get additional information displayed as a tooltip.
+
+- **Needs Owners' Approval**\
+  A file owner either has not voted or voted negatively or not with sufficient
+  score.
+\
+![status not ready hover](./files-owners-status-not-ready-hover.png "Status not ready hover")
+
+
+    > **Notes:**
+    >
+    > The dialog contains up to **5** first file owners returned by the
+    > @PLUGIN@ plugin's REST API.
+    >
+    > Apart from the owner's name, their votes (if cast) and
+    > `Copy owner's email to clipboard` button are shown.
+    >
+    > Hovering over the owner's name results in their details being displayed
+
+
+    ![owner details hover](./owner-details.png "Owner details hover")
+
+- **Approved by Owners**\
+  A file owner has approved the change.
+\
+![status ready hover](./files-owners-status-ready-hover.png "Status ready hover")
+
+
+    > Note that again, apart from the owner's name, their vote and
+    > `Copy owner's email to clipboard` button are shown, and owner's details are
+    > displayed when one hovers over the name.
+
+### <a id="ownerStatus.submitRule">Owners status for submit rule
+
+ `OWNERS` file can still be evaluated (without a need for the prolog
+predicate being added to the project) by enabling the
+[default submit requirements](config.html#owners.enableSubmitRequirement).
+In this way, results of the `OWNERS` file evaluation are provided to
+Gerrit's change through submit rule (as
+[submit record](/Documentation/rest-api-changes.html#submit-record)) and, if
+applicable, owners status is displayed:
+
+* As an icon prepending the `Code Review from owners` submit requirement
+\
+![submit rule](./submit-rule.png "Submit rule")
+
+
+    > Note that in replacement mode, owner's votes are displayed next to the
+    > `Code Review from owners` submit requirement instead of its status.
+    > It is a Gerrit's core representation of submit rule.
+
+* Next to all owned files (when the newest patchset is selected)
+\
+![files owners status](./files-owners-status.png "Files owners status")
+
+
+    > There is no difference in this aspect between modes.
+
+#### <a id="ownersStatus.submitRule.owners">`Code Review from owners` submit requirement
+
+The `Code Review from owners` (that is available only in
+[replacement mode](config.html#owners.enableSubmitRequirement)) submit
+requirement provides general information if all owned files were approved
+(requirement is satisfied). When hovered, a detailed description is shown
+
+![submit rule hover](./submit-rule-hover.png "Submit rule hover")
+
+#### <a id="ownersStatus.submitRule.files">Per file owners statuses
+
+The owners status per file in replacement mode doesn't differ from
+[submit requirements mode](#ownersStatus.submitRequirement.files).
+
+### Files that are assigned to the current user based on the OWNERS
+
+When the current user is mentioned directly or indirectly via a group
+ownership as the owner of one or more files, the change screen displays
+an additional tab called _Owned Files_.
+
+![owned_files](./owned-files.png "Owned Files")
+
+The tab indicates whether the current user has review duties  based on the
+icon displayed on the right side of the tab. If the icon is an orange
+clock, the current user is required to review the files indicated in the
+tab; otherwise, if the icon is a green tick, then the current user review
+input is not strictly required for the change to be merged.
+
+The list of files included in the _Owned Files_ tab, a subset of the full
+list displayed in the _Files_ tab, are the ones assigned to the
+current user through the OWNERS file.
+
+> **NOTE**: When the `owners.config` has `owners.expandGroups = false`
+> then the association between files and the current user may not be
+> accurate or not available because of the lack of group expansion and
+> account resolution service on the backend. In this case, the
+> _Owned Files_ tab may be absent even if the current user is effectively
+> owner of one or more files in the change.
