+## Update Guide
+
+- consider the new Base Git Tag from the official repo onto which we'll rebase our changes
+
+  > **NOTE** For simplicity, let's consider `2.11.2` is the tag we want to rebase onto.
+  
+- sync our fork to include that Git Tag. On local, after cloning UiPath/FreeRdp, execute the following:
+
+  ```pwsh
+  git fetch --tags --all   # this will fetch all tags from all upstreams, including from FreeRdp/FreeRdp
+  git push --tags          # this will push the new tags to UiPath/FreeRdp
+  ```
+- checkout the `uipath` branch
+- ‼️ create a new branch to backup the current state (i.e. `support/before_update_to_2_11_2`)
+- create **and checkout** a new branch that will be used as a work branch (i.e. `feat/update_to_2_11_2`)
+
+- identify the Commit Hash, which is the parent of our 1st customization Commit
+
+  > **NOTE** At the time of writing, our 1st customization Commit's message's 1st line is `Add uipath changes from previous version (2.0.0-rc3)`
+
+- Make sure you've checked out the work branch (i.e. `feat/update_to_2_11_2), and run **git rebase --onto**, so that all UiPath customization commits are replayed onto the new Base Git Tag:
+
+  ```pwsh
+  git rebase --onto <NEW BASE Git Tag> <Our 1st customization Commit's Hash> <The work branch>
+  ```
+
