TODO

1. Determine Package Use:

 Organization? Internal Use? - You are not subject to distribution
  rights when you keep everything internal. Put the binaries directly
  into the tools directory (as long as total nupkg size is under 1GB).
  When bigger, look to use from a share or download binaries from an
  internal location. Embedded binaries makes for the most reliable use
  of Chocolatey. Use `$fileLocation` (`$file`/`$file64`) and
  `Install-ChocolateyInstallPackage`/`Get-ChocolateyUnzip` in
  tools\chocolateyInstall.ps1.

  You can also choose to download from internal urls, see the next
  section, but ignore whether you have distribution rights or not, it
  doesn't apply. Under no circumstances should download from the
  internet, it is completely unreliable. See
  https://docs.chocolatey.org/en-us/community-repository/community-packages-disclaimer
  to understand the limitations of a publicly available repository.

 Community Repository?
  Have Distribution Rights?
    If you are the software vendor OR the software EXPLICITLY allows
    redistribution and the total nupkg size will be under 200MB, you
    have the option to embed the binaries directly into the package to
    provide the most reliable install experience. Put the binaries
    directly into the tools folder, use `$fileLocation` (`$file`/
    `$file64`) and `Install-ChocolateyInstallPackage`/
    `Get-ChocolateyUnzip` in tools\chocolateyInstall.ps1. Additionally,
    fill out the LICENSE and VERIFICATION file (see 3 below and those
    files for specifics).

    NOTE: You can choose to download binaries at runtime, but be sure
     the download location will remain stable. See the next section.

  Do Not Have Distribution Rights?
    - Note: Packages built this way cannot be 100% reliable, but it's a
      constraint of publicly available packages and there is little
      that can be done to change that. See
      https://docs.chocolatey.org/en-us/community-repository/community-packages-disclaimer
      to better understand the limitations of a publicly available
      repository.
    Download Location is Publicly Available?
      You will need to download the runtime files from their official
      location at runtime. Use `$url`/`$url64` and
      `Install-ChocolateyPackage`/`Install-ChocolateyZipPackage` in
      tools\chocolateyInstall.ps1.
    Download Location is Not Publicly Available?
      Stop here, you can't push this to the community repository. You
      can ask the vendor for permission to embed, then include a PDF of
      that signed permission directly in the package. Otherwise you
      will need to seek alternate locations to non-publicly host the
      package.
    Download Location Is Same For All Versions?
      You still need to point to those urls, but you may wish to set up
      something like Automatic Updater (AU) so that when a new version
      of the software becomes available, the new package version
      automatically gets pushed up to the community repository. See
      https://docs.chocolatey.org/en-us/create/automatic-packages#automatic-updater-au

2. Determine Package Type:

- Installer Package - contains an installer (everything in template is
  geared towards this type of package)
- Zip Package - downloads or embeds and unpacks archives, may unpack
  and run an installer using `Install-ChocolateyInstallPackage` as a
  secondary step.
- Portable Package - Contains runtime binaries (or unpacks them as a
  zip package) - cannot require administrative permissions to install
  or use
- Config Package - sets config like files, registry keys, etc
- Extension Package - Packages that add PowerShell functions to
  Chocolatey - https://docs.chocolatey.org/en-us/features/extensions
- Template Package - Packages that add templates like this for `choco
  new -t=name` - https://docs.chocolatey.org/en-us/guides/create/create-custom-package-templates
- Other - there are other types of packages as well, these are the main
  package types seen in the wild

3. Fill out the package contents:

- tools\chocolateyBeforeModify.ps1 - remove if you have no processes
  or services to shut down before upgrade/uninstall
- tools\LICENSE.txt / tools\VERIFICATION.txt - Remove if you are not
  embedding binaries. Keep and fill out if you are embedding binaries
  in the package AND pushing to the community repository, even if you
  are the author of software. The file becomes easier to fill out
  (does not require changes each version) if you are the software
  vendor. If you are building packages for internal use (organization,
  etc), you don't need these files as you are not subject to
  distribution rights internally.
- tools\chocolateyUninstall.ps1 - remove if autouninstaller can
  automatically uninstall and you have nothing additional to do during
  uninstall
- Readme.txt - delete this file once you have read over and used
  anything you've needed from here
- nuspec - fill this out, then clean out all the comments (you may wish
  to leave the headers for the package vs software metadata)
- tools\chocolateyInstall.ps1 - instructions in next section.

4. ChocolateyInstall.ps1:

- For embedded binaries - use `$fileLocation` (`$file`/`$file64`) and
  `Install-ChocolateyInstallPackage`/ `Get-ChocolateyUnzip`.
- Downloading binaries at runtime - use `$url`/`$url64` and
  `Install-ChocolateyPackage` / `Install-ChocolateyZipPackage`.
- Other needs (creating files, setting registry keys), use regular
  PowerShell to do so or see if there is a function already defined:
  https://docs.chocolatey.org/en-us/create/functions
- There may also be functions available in extension packages, see
  https://community.chocolatey.org/packages?q=id%3A.extension for examples and
  availability.
- Clean out the comments and sections you are not using.

5. Test the package to ensure install/uninstall work appropriately.
 There is a test environment you can use for this -
 https://github.com/chocolatey/chocolatey-test-environment

6. Learn more about Chocolatey packaging - go through the workshop at
 https://github.com/chocolatey/chocolatey-workshop
 You will learn about
 - General packaging
 - Customizing package behavior at runtime (package parameters)
 - Extension packages
 - Custom packaging templates
 - Setting up an internal Chocolatey.Server repository
 - Adding and using internal repositories
 - Reporting
 - Advanced packaging techniques when installers are not friendly to
   automation

7. Delete this file.
