Looks like the doc todos need to be done and removed. Everything else looks good. We will want this on pypi so the Blinka boards use it too.

Please add the following in place of #-- PASTE ENCRYPTED PASSWORD HERE --# on line 34 of .travis.yml:

Then delete both TODO: comment blocks in the same file and make the changes listed below.

Please ping me if any of this is unclear. Thanks!

I was unable to review lines not included in changes, so the review includes half of the necessary changes in a review comment, and half of them on the specific lines requiring changes. Please let me know if any of it is unclear. Thank you!

See below to resolve the current Travis issue.

@rhooper @kattni, sorry I just noticed this. let's get this using the actions workflow instead of setting up travis only to have Dylan undo it.

[siddacious]

Looks good, just have to add the build badge and it should be good to go on my end

[tannewt]

The release.yml and build.yml are in the incorrect location. They should be in .github/workflows/ iirc. They should run if it is set up correctly.

[rhooper]

Sorry about that, I haven't used github actions before, so incorrectly assumed they were just like all other CI/CD systems I've used - that look in the root directory by default for CI/CD config.

I see cookiecutter got updated a day after I used it last :)

[siddacious]

Great review job @siddacious 🙄

[rhooper]

Once this gets merged to master and put in PyPi I can finish getting https://github.com/rhooper/Adafruit_CircuitPython_DotStar/tree/pixelbuf
and
https://github.com/rhooper/Adafruit_CircuitPython_NeoPixel/tree/pixelbuf
to pass the build.

[tannewt]

Thank you!

[kattni]

@rhooper This is now on PyPI! We can move forward with NeoPixel and DotStar at any time.
