-# Confluent Cloud Integration
+## Confluent Cloud Integration
 Rather than using a local kafka instance, this project can utilize an instance of kafka hosted by Confluent Cloud via SASL.
 
-## Environment variables
-### Purpose & Usage
+### Environment variables
+#### Purpose & Usage
 - The DOCKER_HOST_IP environment variable is used to communicate with the bootstrap server that the instance of Kafka is running on.
 - The KAFKA_TYPE environment variable specifies what type of kafka connection will be attempted and is used to check if Confluent should be utilized. If this is not set to "CONFLUENT", the PPM will attempt to connect to a local kafka instance.
 - The CONFLUENT_KEY and CONFLUENT_SECRET environment variables are used to authenticate with the bootstrap server. These are the API key and secret that are generated when a new API key is created in Confluent Cloud. These are only used if the KAFKA_TYPE environment variable is set to "CONFLUENT".
 
-### Values
+#### Values
 - DOCKER_HOST_IP must be set to the bootstrap server address (excluding the port)
 - KAFKA_TYPE must be set to "CONFLUENT"
 - CONFLUENT_KEY must be set to the API key being utilized for CC
 - CONFLUENT_SECRET must be set to the API secret being utilized for CC
 
-## CC Docker Compose File
+### CC Docker Compose File
 There is a provided docker-compose file (docker-compose-confluent-cloud.yml) that passes the above environment variables into the container that gets created. Further, this file doesn't spin up a local kafka instance since it is not required.
 
-## Note
+### Note
 This has only been tested with Confluent Cloud but technically all SASL authenticated Kafka brokers can be reached using this method.
 
-# Testing/Troubleshooting
-## Unit Tests
-Unit tests can be built and executed using the build_and_run_unit_tests.sh file inside of the dev container for the project. More information about this can be found [here](./docs/testing.md#utilizing-the-build_and_run_unit_testssh-script).

-The unit tests are also built when the solution is compiled. For information on that, check out [this section](./docs/testing.md#unit-testing).
+## Testing/Troubleshooting
+### Unit Tests
+Unit tests can be built and executed using the build_and_run_unit_tests.sh file inside of the dev container for the project. Alternatively, they can be run inside of the deployed PPM container. More information about this can be found [here](./docs/testing.md#unit-testing).

+To utilize this, run the following command in the root directory of the project:

 Sometimes kafka will fail to start up properly. If this happens, spin down the containers and try again.
 
-### Data & Config Files
+#### Data & Config Files
 Data and config files are expected to be in a location pointed to by the DOCKER_SHARED_VOLUME environment variable.
 
 At this time, the PPM assumes that this location is the /ppm_data directory. When run in a docker or k8s solution, an external drive/directory can be mounted to this directory.

 The path to this file is specified by the REDACTION_PROPERTIES_PATH environment variable. If this is not set, field redaction will not take place but the PPM will continue to function. If this is set and the file is not found, the same behavior will occur.
 
 When running the project in the provided dev container, the REDACTION_PROPERTIES_PATH environment variable should be set to the project-level fieldsToRedact.txt file for debugging/experimentation purposes. This is located in /workspaces/jpo-cvdp/config/fieldsToRedact.txt from the perspective of the dev container.

+### Build & Exec Script
 The [`build_and_exec.sh`](./build_and_exec.sh) script can be used to build a tagged image of the PPM, run the container & enter it with an interactive shell. This script can be used to test the PPM in a standalone environment.
 
 This script should be run outside of the dev container in an environment where Docker is available.
 
 It should be noted that this script needs to use the LF end-of-line sequence.
 
-## Kafka Test Script
-The [do_kafka_test.sh](./do_kafka_test.sh) script is designed to perform integration tests on a Kafka instance. To execute the tests, this script relies on the following scripts: standalone.sh, standalone_multi.sh, do_bsm_test.sh, and do_tim_test.sh.
+### Kafka Test Script
+The [do_kafka_test.sh](./do_kafka_test.sh) script is designed to perform integration tests on a Kafka instance. To execute the tests, this script relies on the `standalone.sh` and `do_bsm_test.sh` scripts.
 
 To ensure proper execution, it is recommended to run this script outside of the dev container where docker is available. This is because the script will spin up a standalone kafka instance and will not be able to access the docker daemon from within the dev container.
 
 It should be noted that this script and any dependent scripts need to use the LF end-of-line sequence. These include the following:

+#### How are fields redacted?
 The paths in the fieldsToRedact.txt file area are added to a list and then used to search for the fields in the BSM message.

There are some exceptions to this which are listed in the [Overridden Redaction Behavior](#overridden-redaction-behavior) section.

 Since it would be incorrect for a bitstring to be missing bits, the PPM will remove the entire bitstring if any of its bits are redacted. This is done by removing the parent object.
