+# Python Tensor Toolbox Contributor Guide
+
+## Issues
+If you are looking to get started or want to propose a change please start by checking
+current or filing a new [issue](https://github.com/sandialabs/pyttb/issues).
+
+## Working on PYTTB locally
+1. clone your fork and enter the directory
+    ```
+    git clone [email protected]:<your username>/pyttb.git
+    cd pyttb
+    ```
+    1. setup your desired python environment as appropriate
+
+1. install dependencies
+    ```
+    We use a mix of pyproject.toml, and setup.py currently. We are
+    still iterating on simplifying the setup procedure.
+    ```
+
+1. Checkout a branch and make your changes
+    ```
+    git checkout -b my-new-feature-branch
+    ```
+1. Formatters and linting
+   1. Run autoformatters from root of project (they will change your code)
+       ```commandline
+       isort .
+       black .
+       ```
+   1. Pylint and mypy coverage is work in progress (these only raise errors)
+      ```commandline
+      mypy pyttb/
+      pylint pyttb/file_name.py  //Today only tensor is compliant
+      ```
+
+1. Run tests (at desired fidelity)
+    1. Just doctests (enabled by default)
+        ```commandline
+        pytest
+        ```
+   1. Functional tests
+        ```commandline
+        pytest .
+        ```
+   1. All tests (linting and formatting checks)
+        ```commandline
+        pytest . --packaging
+        ```
+   1. With coverage
+        ```commandline
+        pytest . --cov=pyttb --cov-report=term-missing
+        ```
