 These tests attempt to ensure forward and backward compatibility for Dolt versions.
 
-For each Dolt release version listed in `versions.txt`, `runner.sh` creates a legacy Dolt repository using the
-`/test_files/setup_repo.sh` script in a directory named with the corresponding version.
-An additional Dolt repository is created using Dolt built from the initial git branch.
-BATS tests, located in `test_files/bats/`, are used to verify the forward and backward compatibility of all Dolt versions
-and the repositories created with those versions.
+For each Dolt release version listed in `test_files/backward_compatible_versions.txt`, a legacy repository is created 
+using the corresponding release and populated with data from `test_files/setup_repo.sh`.
+Then, using a Dolt client build at HEAD, a series of BATS tests are run against each legacy repository. 
+
+To test forward compatibility, a repository is created and populated using Dolt built at HEAD.
+For each Dolt release version listed in `test_files/forward_compatible_versions.txt`, the same BATS tests are run 
+against the repo created with Dolt at HEAD.
