-### Reporting Bugs
-**TODO**
-### Suggesting Enhancements
-**TODO**
-### Localization
-**TODO**
-### Code Contribution
-**TODO**
-### Pull Requests
-Please follow these steps to have your contribution considered by the maintainers:
-
-1. Keep Pull Request specific to one feature or bug.
-2. Follow the [style guides](#style-guides)
-3. After you submit your pull request, verify that all [status checks](https://help.github.com/articles/about-status-checks/) are passing <details><summary>What if the status checks are failing?</summary>If a status check is failing, and you believe that the failure is unrelated to your change, please leave a comment on the pull request explaining why you believe the failure is unrelated. A maintainer will re-run the status check for you. If we conclude that the failure was a false positive, then we will open an issue to track that problem with our status check suite.</details>
-
-While the prerequisites above must be satisfied prior to having your pull request reviewed, the reviewer(s) may ask you to complete additional design work, tests, or other changes before your pull request can be ultimately accepted.
-
-## Style Guides
-### Git Commit Messages
-- Use the present tense ("Add feature" not "Added feature")
-- Use the imperative mood ("Move cursor to..." not "Moves cursor to...")
-- Limit the first line to 72 characters or less
-- Reference issues and pull requests liberally after the first line
-
-### Python Style Guide
-- All files are formatted with [Black](https://github.com/psf/black)
-- Follow [PEP 8](https://peps.python.org/pep-0008/) as much as practical
-- Pass [flake8](https://flake8.pycqa.org/en/latest/) linting
-- Include [PEP 484](https://peps.python.org/pep-0484/) type hints (new code)

 ### Prerequisites
-* [Python 3.7+][python]
+* [Python 3.6+][python]
 * PyQt5
 
 ### System Setup
 When running in a linux based environment the following system packages or equivalents are needed to build:
 * python3-pyqt5
 * pyqt5-dev-tools (on some systems, see note)
+* python3-wheel (for hsaudiotag3k)
 * python3-venv (only if using a virtual environment)
 * python3-dev
 * build-essential
 
+
 Note: On some linux systems pyrcc5 is not put on the path when installing python3-pyqt5, this will cause some issues with the resource files (and icons). These systems should have a respective pyqt5-dev-tools package, which should also be installed. The presence of pyrcc5 can be checked with `which pyrcc5`.  Debian based systems need the extra package, and Arch does not.
