 ### Running tests
 
-> You will need to run `git lfs pull` to retrieve testdata stored in git lfs. If you do not have git-lfs installed on your system,
-> you can refer to: https://github.com/git-lfs/git-lfs#getting-started for git-lfs installation.
-
-Run the unit tests by running `cabal test unit-tests` in the base directory.
+#### Prerequisites
+- You will need to run `git lfs install` and `git lfs pull` to retrieve test data stored in git lfs. If you do not have git-lfs installed on your system, you can refer to: https://github.com/git-lfs/git-lfs#getting-started for git-lfs installation.
+- Create a GitHub Personal Access Token with repo access to FOSSA repos. Store the token in the environment variable `GITHUB_TOKEN`.
+- Download vendor dependencies by running `./vendor_download.sh`.
+- Run `make clean`. You'll need to run a fresh build after downloading the vendor dependencies.
+
+#### Running the tests
+Run the unit tests by running `make test-cabal` in the base directory.
 
 Integration tests require you first build test data by running `make build-test-data`.  Then you can run them with `cabal test integration-tests`.  Integration tests also require `nix`. See ["Installing Nix"](#installing-nix) below for installation instructions. Note that integration tests can take quite a while to run and do not have progress output.
