 ## Overview
 
-OpenHarmony project handles contributions as [merge requests](https://docs.gitlab.com/ee/user/project/merge_requests/) to relevant repositories part of the OpenHarmony [GitLab instance](https://git.ostc-eu.org/OSTC/OHOS). The flow for handling that is classic: fork-based merge requests. This means that once you have an account, you can fork any repository, create a branch with proposed changes and raise a merge request against the forked repository. More generic information you can find on the Gitlab's documentation as part of ["Merge requests workflow"](https://docs.gitlab.com/ee/development/contributing/merge_request_workflow.html).

 This layer builds a subset of the ACTS (Application Compatibility Test Suite)
-for Open Harmony OS. Some tests are not ported yet. Some tests are excluded
+for All Scenarios OS. Some tests are not ported yet. Some tests are excluded
 because they are duplicated in the greater bitbake ecosystem (e.g. LTP). Some
 tests are hardware or kernel specific and are not considered in this phase yet.
