 # DESCRIPTION--------------------------------------------------------------------------
-# This configuration defines three main CI trigger patterns:
-# 1. Pull Request Validation: Validation performed on PR basis
-# 2. Nightly Development: Test set run nightly (validates most important test cases)
-# 3. Weekly Full Validation: Test set run weekly (validates all test cases to prevent any surprises)
-# Each pattern represents different balance between validation depth, execution time and CI resource usage

 # Pull Request:
-# This test validates Standards, Package tests, Project tests and Desktop standalone tests to ensure that main platforms are covered
-# Triggers on PRs to develop, develop, and release branches
-# Focuses on critical validation paths that we should validate before merging PRs
-# Cancels previous runs on new commits
-# Excludes draft PRs
+  # This test validates Standards, Package tests, Project tests and Desktop standalone tests to ensure that main platforms are covered
+  # Focuses on critical validation paths that we should validate before merging PRs. It also cancels previous runs on new commits
+  # By default it's triggered if
+    # 1) PR targets develop, develop-2.0.0 or release branches
+    # 2) PR is not a draft
+    # 3) PR changes files in package or testproject folders (doesn't run on for example DOCS only changes)
+
+  # Note that in other cases you can trigger it by writing a comment "/ci ngo" in the PR thread
 
 # Nightly:
-# This test validates same subset as pull_request_trigger with addition of mobile/console tests and webgl builds
-# Runs daily on develop (local configuration)
-# Includes all test types but only on trunk.

 # Weekly:
-# This test validates same subset as develop_nightly but runs per all supported editors as well as executes code coverage test and runs project standards per project

 # CONFIGURATION STRUCTURE--------------------------------------------------------------
-# Jobs configurations are generated by ensuring that all dependencies are successful.
-# The dependencies are taken from _run-all.yml file where we can gather multiple tests into proper sets

 # QUALITY CONSIDERATIONS---------------------------------------------------------------
-# It's important to ensure that all dependencies exist (this can be verified in Yamato) since a modification in parameters may result in a given job not being generated, and thus we will not be able to run such erroneous job.

 # Run all relevant tasks when a pull request targeting the develop or release branch is created or updated.
 # In order to have better coverage we run desktop standalone tests with different configurations which allows to mostly cover for different platforms, scripting backends and editor versions.
 # This job will FIRST run "run_quick_checks" jobs (defined in _run-all.yml) since it's the dependency of project pack jobs which is on the lowest dependency tier. This runs the fastest checks (like PVP or code standards) and ONLY IF those pass it will run the rest of the tests.
