 # How to service a library
 
-This document provides the steps necessary after modifying a library in a servicing branch (where "servicing branch" refers to any branch whose name begins with `release/`).
+This document provides the steps necessary after modifying a library in a servicing branch.
+
+Servicing branches represent shipped versions of .NET, and their name is in the format `release/X.0-staging`. Examples:
+
+- `release/7.0-staging`
+- `release/6.0-staging`
 
 ## Check if a package is generated
 
 If a library is packable (check for the `<IsPackable>true</IsPackable>` property) you'll need to set `<GeneratePackageOnBuild>true</GeneratePackageOnBuild>` in the source project. That is necessary as packages aren't generated by default in servicing releases.
 
+Additionally, if the library is listed among the project references of [Microsoft.Windows.Compatibility.csproj](https://github.com/dotnet/runtime/blob/43bb5993d4f983e9d575f52b691ecdc9b9e257ef/src/libraries/Microsoft.Windows.Compatibility/src/Microsoft.Windows.Compatibility.csproj#L15-L48), please make sure to bump the value of `ServicingVersion` for `Microsoft.Windows.Compatibility.csproj` and also set its `GeneratePackageOnBuild` property value to `true`. The version number must only be bumped once per servicing release, even if multiple dependencies get modified.
+
 ## Determine ServiceVersion
 
 When you make a change to a library & ship it during the servicing release, the `ServicingVersion` must be bumped. This property is found in the library's source project. It's also possible that the property is not in that file, in which case you'll need to add it to the library's source project and set it to 1. If the property is already present in your library's source project, just increment the servicing version by 1.

 ## Approval Process
 
-All the servicing change must go through an approval process. Please create your PR using [this template](https://raw.githubusercontent.com/dotnet/runtime/main/.github/PULL_REQUEST_TEMPLATE/servicing_pull_request_template.md). You should also add `servicing-consider` label to the pull request and bring it to the attention of the engineering lead responsible for the area.
+All the servicing change must go through an approval process. You have two ways to submit your PR:
+
+- By manually creating your PR using [this template](https://raw.githubusercontent.com/dotnet/runtime/main/.github/PULL_REQUEST_TEMPLATE/servicing_pull_request_template.md).
+- Or by asking the bot to automatically create the servicing PR for you using a merged `main` PR as source. This method requires typing an AzDO backport command as a comment of your merged PR using the format `/backport to release/X.0-staging`. Examples:
+-
+  - `/backport to release/7.0-staging`
+  - `/backport to release/6.0-staging`
+
+For both cases, you must:
+
+- Fill out the template of the PR description.
+- Add the `servicing-consider` label.
+- Bring it to the attention of the engineering lead responsible for the area, so they consider the fix for servicing.
