Chocolatey v0.10.15
Install Command

Installs a package or a list of packages (sometimes specified as a
 packages.config). Some may prefer to use `cinst` as a shortcut for
 `choco install`.

NOTE: 100% compatible with older chocolatey client (0.9.8.32 and below)
 with options and switches. Add `-y` for previous behavior with no
 prompt. In most cases you can still pass options and switches with one
 dash (`-`). For more details, see the command reference (`choco -?`).

Usage

    choco install <pkg|packages.config> [<pkg2> <pkgN>] [<options/switches>]
    cinst <pkg|packages.config> [<pkg2> <pkgN>] [<options/switches>]

NOTE: `all` is a special package keyword that will allow you to install
 all packages from a custom feed. Will not work with Chocolatey default
 feed. THIS IS NOT YET REIMPLEMENTED.

NOTE: Any package name ending with .config is considered a
 'packages.config' file. Please see https://bit.ly/packages_config

NOTE: Chocolatey Pro / Business builds on top of a great open source
 experience with quite a few features that enhance the your use of the
 community package repository (when using Pro), and really enhance the
 Chocolatey experience all around. If you are an organization looking
 for a better ROI, look no further than Business - automatic package
 creation from installer files, automatic recompile support, runtime
 malware protection, private CDN download cache, synchronize with
 Programs and Features, etc - https://chocolatey.org/compare.


Examples

    choco install sysinternals
    choco install notepadplusplus googlechrome atom 7zip
    choco install notepadplusplus --force --force-dependencies
    choco install notepadplusplus googlechrome atom 7zip -dvfy
    choco install git -y --params="'/GitAndUnixToolsOnPath /NoAutoCrlf'"
    choco install git -y --params="'/GitAndUnixToolsOnPath /NoAutoCrlf'" --install-arguments="'/DIR=C:\git'"
    # Params are package parameters, passed to the package
    # Install args are installer arguments, appended to the silentArgs
    #  in the package for the installer itself
    choco install nodejs.install --version 0.10.35
    choco install git -s "'https://somewhere/out/there'"
    choco install git -s "'https://somewhere/protected'" -u user -p pass

Choco can also install directly from a nuspec/nupkg file. This aids in
 testing packages:

    choco install <path/to/nuspec>
    choco install <path/to/nupkg>

Install multiple versions of a package using -m (AllowMultiple versions)

    choco install ruby --version 1.9.3.55100 -my
    choco install ruby --version 2.0.0.59800 -my
    choco install ruby --version 2.1.5 -my

What is `-my`? See option bundling in the command reference
 (`choco -?`).

NOTE: All of these will add to PATH variable. We'll be adding a special
 option to not allow PATH changes. Until then you will need to manually
 go modify Path to just one Ruby and then use something like uru
 (https://bitbucket.org/jonforums/uru) or pik
 (https://chocolatey.org/packages/pik) to switch between versions.

NOTE: See scripting in the command reference (`choco -?`) for how to
 write proper scripts and integrations.


Exit Codes

Exit codes that normally result from running this command.

Normal:
 - 0: operation was successful, no issues detected
 - -1 or 1: an error has occurred

Package Exit Codes:
 - 1641: success, reboot initiated
 - 3010: success, reboot required
 - other (not listed): likely an error has occurred

In addition to normal exit codes, packages are allowed to exit
 with their own codes when the feature 'usePackageExitCodes' is
 turned on. Uninstall command has additional valid exit codes.
 Available in v0.9.10+.

Reboot Exit Codes:
 - 350: pending reboot detected, no action has occurred
 - 1604: install suspended, incomplete

In addition to the above exit codes, you may also see reboot exit codes
 when the feature 'exitOnRebootDetected' is turned on. It typically requires
 the feature 'usePackageExitCodes' to also be turned on to work properly.
 Available in v0.10.12+.

Packages.config

Alternative to PackageName. This is a list of packages in an xml manifest for Chocolatey to install. This is like the packages.config that NuGet uses except it also adds other options and switches. This can also be the path to the packages.config file if it is not in the current working directory.

NOTE: The filename is only required to end in .config, the name is not required to be packages.config.

    <?xml version="1.0" encoding="utf-8"?>
    <packages>
      <package id="apackage" />
      <package id="anotherPackage" version="1.1" />

Alternative Sources

Available in 0.9.10+.

Ruby
This specifies the source is Ruby Gems and that we are installing a
 gem. If you do not have ruby installed prior to running this command,
 the command will install that first.
 e.g. `choco install compass -source ruby`

WebPI
This specifies the source is Web PI (Web Platform Installer) and that
 we are installing a WebPI product, such as IISExpress. If you do not
 have the Web PI command line installed, it will install that first and
 then the product requested.
 e.g. `choco install IISExpress --source webpi`

Cygwin
This specifies the source is Cygwin and that we are installing a cygwin
 package, such as bash. If you do not have Cygwin installed, it will
 install that first and then the product requested.
 e.g. `choco install bash --source cygwin`

Python
This specifies the source is Python and that we are installing a python
 package, such as Sphinx. If you do not have easy_install and Python
 installed, it will install those first and then the product requested.
 e.g. `choco install sphinx --source python`

Windows Features
This specifies that the source is a Windows Feature and we should
 install via the Deployment Image Servicing and Management tool (DISM)
 on the local machine.
 e.g. `choco install IIS-WebServerRole --source windowsfeatures`

   when creating a Chocolatey Package can be seen at

Options and Switches

NOTE: Options and switches apply to all items passed, so if you are
 installing multiple packages, and you use `--version=1.0.0`, it is
 going to look for and try to install version 1.0.0 of every package
 passed. So please split out multiple package calls when wanting to
 pass specific options.
