Todo before demos

basic-public

You don't need to do anything before the basic-public demo.

basic-private

Before the basic-private demo, make sure to run:

$ git config --global --add url."git@github.com:".insteadOf "https://github.com/"

So that the go tool will check out private code from GitHub over SSH.

This command is in the steps of the README in that demo

athens-private

You'll need a GitHub personal access token for this. Create one here. When you create it, just enable the repo scope and nothing else.

After you have it, store it in an environment variable on the command line. Here's how to do it on Linux/Mac systems:

$ export ATHENS_GITHUB_TOKEN="<your token>"

Then you'll be ready to run that demo.
