Ketarin / ChocolateyPackageUpdater Automatic Packaging

Review ketarin_setup.ps1 to ensure all items are set appropriately. Uncomment/change anything you need to now.
Run ketarin_setup.ps1
Open ketarin after installing it, open the settings and import KetarinSettings.xml.
Set up push for Chocolatey community feed with your API key.
Ensure git push doesn't require credentials.
Review ops/ketarinupdate.cmd to ensure it is good to go.

Note: Use ops/ketarinupdate.cmd or similar to schedule updates.

Review au_setup.ps1 to ensure all items are set appropriately. Uncomment/change anything you need to now.
Run au_setup.ps1.
Log into https://gist.github.com with the user you want to use to perform commits and pushes to git.
Create an empty gist (secret or not). Grab the id at the end of it - https://gist.github.com/name/{id}. You will need that for appveyor.yml and update_vars.ps1.
Now we need to set up AppVeyor and our local runs.

Go to AppVeyor and sign up/sign in. https://ci.appveyor.com/
Set up an appveyor job - https://ci.appveyor.com/projects/new
Select your repository to create a new job.
Go to settings ensure the following items are set (these items cannot be configured in the yaml):
- In Build Schedule, we want to run this three times a day - set it like this: 5 */6 * * * *. This ensures it runs at 06:05, 12:05, and 18:05.
- "Ensure Skip branches without appveyor.yml" is checked.
- "Enable secure variables in Pull Requests from the same repository only" is checked.
- Click Save.
Get encrypted values for - https://ci.appveyor.com/tools/encrypt (requires login first)
- github password (or auth token for 2FA)
- email password
- Chocolatey API key
Edit the appveyor.yml to add those values in.
Edit the appveyor.yml with the other configuration related items.

Edit au/update_vars.ps1 and set the same variables there.
As part of setup, you ensured that you have the Ruby gem gist installed. Please run gist --login to provide your credentials
Ensure git push doesn't require credentials.

Note: You can also set up a scheduled task for local runs.

If you use Google mail for error notifications on a build server such as AppVeyor, Google may block authentication from unknown device. To receive those emails enable less secure apps - see Allowing less secure apps to access your account. In any case, do not use your private email for this but create a new Google account and redirect its messages to your private one. This wont affect you if you run the scripts from your own machine from which you usually access the email.
If you are using AppVeyor you should schedule your build under the General options using Cron syntax, for example 0 22 * * * * runs the updater every night at 22h. 5 * * * * * runs the updater every hour at five past the hour.
For gist to work the over proxy you need to set console proxy environment variable. See Update-CLIProxy function.
