 1.  Copy `.secrets.default` to `.secrets` in the `tests` folder and change the parameters and add the additional s3 fields explained in the **S3 Backend** section above if running with the s3 backend.
 2.  By default, the dockerfile uses the **arm** architecture (usually modern Mac).  If using **amd** (usually earlier Mac or Linux), you can either replace the corresponding `ARG` values directly, or with `arg="<param>=<amd library or folder>"`  Also, you can determine which is used by your OS with `uname -a`.
 3.  Build and run the `Dockerfile_test_bats` file.  Change the `SECRETS_FILE` and `CONFIG_FILE` parameters to point to your secrets and config file, respectively, if not using the defaults.  Example:  `docker build -t <tag> -f Dockerfile_test_bats --build-arg="SECRETS_FILE=<file>" --build-arg="CONFIG_FILE=<file>" .`.
+4.  To run the entire suite, run `docker run -it <image name>`.  To run an individual suite, pass in the name of the suite as defined in `tests/run.sh` (e.g. REST tests -> `docker run -it <image name> rest`).  Also, multiple specific suites can be run, if separated by comma.

+## Environment Parameters
+
+### Secret
+
+**AWS_PROFILE**, **AWS_ENDPOINT_URL**, **AWS_REGION**, **AWS_ACCESS_KEY_ID**, **AWS_SECRET_ACCESS_KEY**:  identical to the same parameters in **s3**.
+
+**AWS_CANONICAL_ID**:  for direct mode, the canonical ID for the main user (owner)
+
+**ACL_AWS_CANONICAL_ID**:  for direct mode, the canonical ID for the user to test ACL changes and access by non-owners
+
+**ACL_AWS_ACCESS_KEY_ID**, **ACL_AWS_ACCESS_SECRET_KEY**:  for direct mode, the ID and key for the S3 user in the **ACL_AWS_CANONICAL_ID** account.
+
+### Non-Secret
+
+**VERSITY_EXE**:  location of the versity executable relative to test folder.
+
+**RUN_VERSITYGW**:  whether to run the versitygw executable, should be set to **false** when running tests directly against **s3**.
+
+**BACKEND**:  the storage backend type for the gateway, e.g. **posix** or **s3**.
+
+**LOCAL_FOLDER**:  if running with a **posix** backend, the backend storage folder.
+
+**BUCKET_ONE_NAME**, **BUCKET_TWO_NAME**:  test bucket names.
+
+**RECREATE_BUCKETS**:  whether to delete buckets between tests.  If set to false, the bucket will be restored to an original state for the purpose of ensuring consistent tests, but not deleted.
+
+**CERT**, **KEY**:  certificate and key locations if using SSL.
+
+**S3CMD_CONFIG**:  location of **s3cmd** config file if running **s3cmd** tests.
+
+**SECRETS_FILE**:  file where sensitive values, such as **AWS_SECRET_ACCESS_KEY**, should be stored.
+
+**MC_ALIAS**:  Minio MC alias if running MC tests.
+
+**LOG_LEVEL**:  level for test logger (1 - only critical, 2 - errors, 3 - warnings, 4 - info, 5 - debug info, 6 - tracing)
+
+**GOCOVERDIR**:  folder to put golang coverage info in, if checking coverage info.
+
+**USERS_FOLDER**:  folder to use if storing IAM data in a folder.
+
+**IAM_TYPE**:  how to store IAM data (**s3** or **folder**).
+
+**TEST_LOG_FILE**:  log file location for these bats tests.
+
+**VERSITY_LOG_FILE**:  log file for versity application as it is tested by bats tests.
+
+**DIRECT**:  if **true**, bypass versitygw and run directly against s3 (for comparison and validity-checking purposes).
+
+**DIRECT_DISPLAY_NAME**:  username if **DIRECT** is set to **true**.
+
+**COVERAGE_DB**:  database to store client command coverage info and usage counts, if using.
+
+**USERNAME_ONE**, **PASSWORD_ONE**, **USERNAME_TWO**, **PASSWORD_TWO**:  credentials for users created and tested for non-root user **versitygw** operations.
+
+**TEST_FILE_FOLDER**:  where to put temporary test files.
+
+**REMOVE_TEST_FILE_FOLDER**:  whether to delete the test file folder between tests, should be set to **true** unless checking the files after a single test, or not yet sure that the test folder is in a safe location to avoid deleting other files.
+
+**VERSIONING_DIR**:  where to put gateway file versioning info.
+
+**COMMAND_LOG**:  where to store list of client commands, which if using will be reported during test failures.
+
+**TIME_LOG**:  optional log to show duration of individual tests
+
+**DIRECT_S3_ROOT_ACCOUNT_NAME**:  for direct mode, S3 username
+
+**DELETE_BUCKETS_AFTER_TEST**:  whether or not to delete buckets after individual tests, useful for debugging if the post-test bucket state needs to be checked
+
+## REST Scripts
+
+REST scripts are included for calls to S3's REST API in the `./tests/rest_scripts/` folder.  To call a script, the following parameters are needed:
+* **AWS_ACCESS_KEY_ID**, **AWS_SECRET_ACCESS_KEY**, etc.
+* **AWS_ENDPOINT_URL** (default:  `https://localhost:7070`)
+* **OUTPUT_FILE**:  file where the command's response data is written
+* Any other parameters specified at the top of the script file, such as payloads and variables.  Sometimes, defaults are included.
+
+Upon success, the script will return a response code, and write the data to the **OUTPUT_FILE** location.
+
+Example:  `AWS_ACCESS_KEY_ID={id} AWS_SECRET_ACCESS_KEY={key} AWS_ENDPOINT_URL=https://s3.amazonaws.com OUTPUT_FILE=./output_file.xml ./tests/rest_scripts/list_buckets.sh`
