+This repository contains plug-in tests for use during validation of submissions. It is referenced by ingest-validation-tools.
 
 ## Development process
 
+### Branches
+
 - Make new feature branches from `devel`.
+- Before submitting a PR, make sure your code is black and isort compliant. Run the following from the base `ingest-validation-tests` directory:
+
+  ```
+  black --line-length 99 .
+  isort --profile black --multi-line 3 .
+  ```
+
+  (You can integrate black and potentially isort with your editor to skip this step, see Setup section below)
+
 - Make PRs to `devel`. (This is the default branch.)
-- The last reviewer to approve a PR should merge it.  At the moment that is likely to be @jswelling .
+- The last reviewer to approve a PR should merge it.
+
+### Setup
+
+- Creating and activating a virtual environment is recommended. These instructions assume you are using a virtual environment. Example using venv:
+
+  ```
+  python3.9 -m venv hm-ingest-validation-tests
+  source hm-ingest-validation-tests/bin/activate
+  ```
+
+- Run `pip install -r requirements-dev.txt`
+- (optional) Integrate black with your editor.
+  - [Instructions for black.](https://black.readthedocs.io/en/stable/integrations/editors.html)
+- (optional) Integrate [isort](https://pycqa.github.io/isort/) with your editor.
+
+### Testing
+
+- If ingest-validation-tools is not already set up:
+
+  ```
+  # Starting from ingest-validation-tests...
+  cd ..
+  git clone https://github.com/hubmapconsortium/ingest-validation-tools.git
+  cd ingest-validation-tests
+  pip install -r ../ingest-validation-tools/requirements.txt
+  pip install -r ../ingest-validation-tools/requirements-dev.txt
+  ```
+
+- If ingest-validation-tools is already set up, add the appropriate ingest-validation-tools path and run:
+
+  ```
+  pip install -r <path-to-ingest-validation-tools>/requirements.txt
+  pip install -r <path-to-ingest-validation-tools>/requirements-dev.txt
+  ```
+
+- Run `test.sh`
