## Preparations
# make sure that no other files under VCS control are changed (even in different change lists) prior to applying the patch
# apply the patch via `arc patch D240` command (usual stuff)
# ensure, that `/tools/build/build.properties` file is present (see [[ preparing-build-environment | Preparing Build Environment ]])
# open `/tools/build/targets/common.xml` file for editing in IDE
* search for `<arg value="--extensions=php"/>`
* after each found line add this line `<arg value="--sniffs=CodingStandard.Commenting.TypeComment"/>`
* save changes
## Plan
* run `phing -f tools/build/build_all.xml phpcs` command
* confirm, that no errors/warnings were found (the above command searches for them)
* run `phing -f tools/build/build_all.xml lint` command
* confirm, that no PHP files contain syntax errors (the above command searches for them)
* look at made changes (in Phabricator)
* confirm, that only type comments are fixed
* confirm, that nothing else is changed/fixed
