+1. Find out to which upstream version you want to roll, and change the value of `playwrightCliVersion` in the **run.go** to the new version.
+1. Apply patch `bash scripts/apply-patch.sh`
+1. Fix merge conflicts if any, otherwise ignore this step. Once you are happy you can commit the changes `cd playwright; git commit -am "apply patch" && cd ..`
+1. Regenerate a new patch `bash scripts/update-patch.sh`
+1. Generate go code `go generate ./...`

+To adapt to the new version of Playwright's protocol and feature updates, you may need to modify the patch. Refer to the following steps:
+
+1. Apply patch `bash scripts/apply-patch.sh`
 1. `cd playwright`
-1. `reset HEAD~1` this reverts the custom patches
-1. `git stash`
-1. checkout new new sha `git checkout <sha>`
-1. apply the patch again `git stash pop` (and fix merge conflicts)
-1. once you are happy you can commit the changes `git commit -am "apply patch"`
-1. regenerate a new patch `bash scripts/update-patch.sh`
+1. Revert the patch`git reset HEAD~1`
+1. Modify the files under `docs/src/api`, etc. as needed. Available references:
+    - Protocol `packages/protocol/src/protocol.yml`, prior to v1.27.0 are available in `packages/playwright-core/src/protocol/protocol.yml`
+    - [Playwright python](https://github.com/microsoft/playwright-python)
+1. Commit the changes `git commit -am "apply patch"`
+1. Regenerate a new patch `bash scripts/update-patch.sh`
+1. Generate go code `go generate ./...`. If you updated `scripts/data/interfaces.json`, do this step again.
