-1. All wheels are generated with `--universal` flag passed to `bdist_wheel`. We do not currently allow non-universal packages to be shipped out of this repository.
+1. All wheels are generated with influence from `setup.cfg` at the built package root. This means that for most of our packages, the `universal` flag is set within the `setup.cfg`.

+```
+[bdist_wheel]
+universal=1
+```
+2. If a package does _not_ have `universal` set, then the default build will produce a wheel for `py3`. This is due to the fact that wheels are currently generated by a CI step running `Python 3.6`.

 1. Install on packages (and their dev_requirements!) in one go.
 2. Run `pytest <folder1>, pytest <folder2>` where folders correspond to package folders
     1. While all packages are installed alongside each other, each test run is individual to the package. This has the benefit of not allowing `packageA`'s `conftest.py` to mess with `packageB`'s environment.'

+A standard pull request will option target the `Individual Packages` option. On a nightly cadence, the `python - client` build installs the entire world and tests in _both_ methodologies outlined above.
