+# Yamato paths disclaimer:
+# Note that artifacts can get only local paths and since cloned project is in different location, you need to be careful with paths
+# All artifact paths are defined relative to the Yamato source directory (YAMATO_SOURCE_DIR) and are case-sensitive.
+# !!! important “Artifact directory locations” All artifact globs are defined relative to the source directory (YAMATO_SOURCE_DIR). Yamato can’t capture artifacts from outside this directory, so if you need files from elsewhere, you should copy them into your source directory as part of job commands.
+
+# Those jobs were created in order to (in most cases) speed up playtesting and development time.
+# The aim is to collect all possible projects that use Netcode for Entities and create a job that will build the project with the given version of N4E package.
+# The package is taken directly from the branch from which the job was triggered. So image triggering the job from release/2.0.0 and release/2.1.0 branch to compare differences
+# Example use case would be to trigger the build job on Sunday so by Monday morning all builds are ready for playtesting. This limits the time a dev/QA has to spend building projects for different configurations (win, mac, Android, scripting backends, burst etc) or simply time necessary for building huge projects (Megacity).
+
+# This job takes parameters as scriptable backend configuration, burst compilation, unity editor version and platform.
+# Since Yamato variables can't be restricted to only specific values, the job will validate the parameters passed to it and fail quickly if those are incorrect. In order to see what options are available, please look at the variable name.
+
+# Note that for now all of those builds are being made on Windows machine (so for example combination of macOS + il2cpp is expected to fail)
+# TODO: for now all builds are being made on Windows machine, but it would be nice to have a Mac build as well.
+# TODO: add iOS support
