+# UPM Package Starter Kit
+
+The purpose of this starter kit is to provide the data structure and development guidelines for new packages meant for the **Unity Package Manager (UPM)**.
+
+## Are you ready to become a package?
+The Package Manager is a work-in-progress for Unity and, in that sense, there are a few criteria that must be met for your package to be considered on the package list at this time:
+- **Your code accesses public Unity C# APIs only.**  If you have a native code component, it will need to ship with an official editor release.  Internal API access might eventually be possible for Unity made packages, but not at this time.
+- **Your code doesn't require security, obfuscation, or conditional access control.**  Anyone should be able to download your package and access the source code.
+
+

+
+## Develop your package
+Package development works best within the Unity Editor.  Here's how to set that up:
+
+1. Start **Unity**, create a local empty project.
+
+1. In a console (or terminal) application, go to the newly created project folder, then copy the contents of this starter kit into the packages directory.
+    __Note:__ Your directory name must be the name of your package (Example: `"com.unity.terrain-builder"`)
+
+1. ##### Fill in your package information
+
+	Update the following required fields in file **package.json**:
+	- `"name"`: Package name, it should follow this naming convention: `"com.[YourCompanyName].[sub-group].[your-package-name]"`
+	(Example: `"com.unity.2d.animation"`, where `sub-group` should match the sub-group you selected in Gitlab)
+	- `"displayName"`: Package user friendly display name. (Example: `"Terrain Builder SDK"`). <br>__Note:__ Use a display name that will help users understand what your package is intended for.
+	- `"version"`: Package version `"X.Y.Z"`, your project **must** adhere to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).
+		Follow this guideline:
+		- To introduce a new feature or bug fix, increment the minor version (X.**Y**.Z)
+		- To introduce a breaking API change, increment the major version (**X**.Y.Z)
+		- The patch version (X.Y.**Z**), is reserved for sustainable engineering use only.
+	- `"unity"`: Unity Version your package is compatible with. (Example: `"2018.1"`)
+	- `"description"`: This description appears in the Package Manager window when the user selects this package from the list. For best results, use this text to summarize what the package does and how it can benefit the user.<br>__Note:__ Special formatting characters are supported, including line breaks (`\n`) and unicode characters such as bullets (`\u25AA`).<br>
+
+	Update the following recommended fields in file **package.json**:
+	- `"dependencies"`: List of packages this package depends on.  All dependencies will also be downloaded and loaded in a project with your package.  Here's an example:
+        ```
+        dependencies: {
+          "com.unity.ads": "1.0.0"
+          "com.unity.analytics": "2.0.0"
+        }
+        ```
+	- `"keywords"`: List of words that will be indexed by the package manager search engine to facilitate discovery.
+
+    Update the following field in file **Tests/.tests.json**:
+    - `"createSeparatePackage"`: If this is set to true, the CI will create a separate package for these tests. If you leave it set to false, the tests will remain part of the published package. If you set it to true, the tests in your package will automatically be moved to a separate package, and metadata will be added at publish time to link the packages together. This allows you to have a large number of tests, or assets, etc. that you don't want to include in your main package, while making it easy to test your package with those tests & fixtures.
+
+1. You should now see your package in the Project Window, along with all other available packages for your project.
+
+1. ##### Rename and update assembly definition files.
+
+	Assembly definition files are used to generate C# assemblies during compilation.  Package code must include asmdef files to ensure package code isolation.  You can read up on assembly definition files [here](https://docs.unity3d.com/Manual/ScriptCompilationAssemblyDefinitionFiles.html).
+
+    If your package contains Editor code, rename and modify [Editor/Unity.YourPackageName.Editor.asmdef](Editor/Unity.YourPackageName.Editor.asmdef). Otherwise, delete the Editor directory.
+	 * Name **must** match your package name, suffixed by `.Editor` (i.e `Unity.[YourPackageName].Editor`)
+	 * Assembly **must** reference `Unity.[YourPackageName]` (if you have any Runtime)
+	 * Platforms **must** include `"Editor"`
+
+    If your package contains code that needs to be included in Unity runtime builds, rename and modify [Runtime/Unity.YourPackageName.asmdef](Runtime/Unity.YourPackageName.asmdef). Otherwise, delete the Runtime directory.
+	 * Name **must** match your package name (i.e `Unity.[YourPackageName]`)
+
+    If your package has Editor code, you **must** include Editor Tests in your package. In that case, rename and modify [Tests/Editor/Unity.YourPackageName.Editor.Tests.asmdef](Tests/Editor/Unity.YourPackageName.Editor.Tests.asmdef).
+	 * Name **must** match your package name, suffixed by `.Editor.Tests` (i.e `Unity.[YourPackageName].Editor.Tests`)
+	 * Assembly **must** reference `Unity.[YourPackageName].Editor` and `Unity.[YourPackageName]` (if you have any Runtime)
+	 * Platforms **must** include `"Editor"`
+	 * Optional Unity references **must** include `"TestAssemblies"` to allow your Editor Tests to show up in the Test Runner/run on Katana when your package is listed in project manifest `testables`
+
+    If your package has Runtime code, you **must** include Playmode Tests in your package. In that case, rename and modify [Tests/Runtime/Unity.YourPackageName.Tests.asmdef](Tests/Runtime/Unity.YourPackageName.Tests.asmdef).
+	* Name **must** match your package name, suffixed by `.Tests` (i.e `Unity.[YourPackageName].Tests`)
+	* Assembly **must** reference `Unity.[YourPackageName]`
+	* Optional Unity references **must** include `"TestAssemblies"` to allow your Playmode Tests to show up in the Test Runner/run on Katana when your package is listed in project manifest `testables`
+
+    >
+    >  The reason for choosing such name schema is to ensure that the name of the assembly built based on *assembly definition file* (_a.k.a .asmdef_) will follow the .Net [Framework Design Guidelines](https://docs.microsoft.com/en-us/dotnet/standard/design-guidelines/index)
+
+1. ##### Document your package.
+    
+    Rename and update **your-package-name.md** documentation file.  Use this documentation template file to create preliminary, high-level documentation. This document is meant to introduce users to the features and sample files included in your package.  Your package documentation files will be used to generate online and local docs, available from the package manager UI.
+
+	**Document your public APIs**
+	* All public APIs need to be documented with XmlDoc.  If you don't need an API to be accessed by clients, mark it as internal instead.
+	* API documentation is generated from [XmlDoc tags](https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/xmldoc/xml-documentation-comments) included with all public APIs found in the package. See [Editor/EditorExample.cs](Editor/EditorExample.cs) for an example.
+
+    **Documentation flow**
+	* Documentation needs to be ready when a publish request is sent to Release Management, as they will ask the documentation team to review it.
+	* The package will remain in `preview` mode until the final documentation is completed.  Users will have access to the developer-generated documentation only in preview packages.
+	* When the documentation is completed, the documentation team will update the package git repo with the updates and they will publish it on the web.
+	* The package's development team will then need to submit a new package version with updated docs.
+	* The starting page in the user manual that links to package documentation is [Here](https://docs.unity3d.com/Manual/PackagesList.html).
+	* The `Documentation~` folder is suffixed with `~` so that its content does not get loaded in the editor, which is the recommended behavior. If this is problematic, you can still name it `Documentation` and all tools will still work correctly. `.Documentation` is also supported.
+
+    **Test your documentation locally**
+    As you are developing your documentation, you can see what your documentation will look like by using the DocTools extension (optional).
+    Once the DocTools package is installed, it will add a `Generate Documentation` button in the Package Manager UI's details of your installed packages. To install the extension, follow these steps:
+
+    1. Make sure you have `Package Manager UI v1.9.6` or above.
+    1. Your project manifest will need to point to a staging registry for this, which you can do by adding this line to it: `"registry": "https://staging-packages.unity.com"`
+    1. Install `Package Manager DocTools v1.0.0-preview.6` or above from the `Package Manager UI` (in the `All Packages` section).
+    1. After installation, you will see a `Generate Documentation` button which will generate the documentation locally, and open a web browser to a locally served version of your documentation so you can preview it.
+    1. (optional) If your package documentation contains multiple `.md` files for the user manual, see [this page](https://docs.unity3d.com/Packages/com.unity.package-manager-doctools@1.0/manual/index.html#table-of-content) to add a table of content to your documentation.
+
+    The DocTools extension is still in preview, if you come across arguable results, please discuss them on #docs-packman.
+
+1. ##### Add samples to your package (code & assets).
+    If your package contains a sample, rename the `Samples/Example` folder, and update the `.sample.json` file in it.
+
+    In the case where your package contains multiple samples, you can make a copy of the `Samples/Example` folder for each sample, and update the `.sample.json` file accordingly.
+
+    Similar to `.tests.json` file, there is a `"createSeparatePackage"` field in `.sample.json`.If set to true, the CI will create an separate package for the sample..
+
+    Delete the `Samples` folder altogether if your package does not need samples.
+
+    As of Unity release 2019.1, the /Samples directory of a package will be recognized by the package manager.  Samples will not be imported to Unity when the package is added to a project, but will instead be offered to users of the package as an optional import, which can be added to their "/Assets" directory  through a UI option.
+
+1. ##### Validate your package.
+
+    Before you publish your package, you need to make sure that it passes all the necessary validation checks by using the Package Validation Suite extension (optional).
+    Once the Validation Suite package is installed, it will add a `Validate` button in the Package Manager UI's details of your installed packages. To install the extension, follow these steps:
+
+    1. Make sure you have `Package Manager UI v1.9.6` or above.
+    1. Your project manifest will need to point to a staging registry for this, which you can do by adding this line to it: `"registry": "https://staging-packages.unity.com"`
+    1. Install `Package Validation Suite v0.3.0-preview.13` or above from the `Package Manager UI` in the `All Packages` section. If you can't find it there, try turning on `Show preview packages` in the `Advanced` menu.
+    1. After installation, you will see a `Validate` button show up in the Package Manager UI, which, when pressed, will run a series of tests and expose a `See Results` button for additional explanation.
+        1. If it succeeds, you will see a green bar with a `Success` message.
+        1. If it fails, you will see a red bar with a `Failed` message.
+
+    The validation suite is still in preview, if you come across arguable results, please discuss them on #release-management.
+
+1. ##### Add tests to your package.
+
+    All packages must contain tests.  Tests are essential for Unity to ensure that the package works as expected in different scenarios.
+  
+	**Editor tests**
+	* Write all your Editor Tests in `Tests/Editor`
+
+    **Playmode Tests**
+	* Write all your Playmode Tests in `Tests/Runtime`.
+
+1. ##### Update **CHANGELOG.md**.
+
+	Every new feature or bug fix should have a trace in this file. For more details on the chosen changelog format, see [Keep a Changelog](http://keepachangelog.com/en/1.0.0/).
+
+## Create a Pre-Release Package
+Pre-Release Packages are a great way of getting your features in front of Unity Developers in order to get early feedback on functionality and UI designs.  Pre-Release packages need to go through the publishing to production flow, as would any other package, but with diminished requirements.  Here are the supported Pre-Release tags (to be used in package.json,`version` field), along with the requirements for each one:
+
+**Preview**  -  ex: `"version" : "1.2.0-preview"`
+  * Expected Package structure respected
+  * Package loads in Unity Editor without errors
+  * License file present - With third party notices file if necessary
+  * Test coverage is good - Optional but preferred
+  * Public APIs documented, minimal feature docs exists- Optional but preferred
+
+## Make sure your package meets all legal requirements    
+
+##### Update **Third Party Notices.md** & **License.md**
+
+1. If your package has third-party elements and its licenses are approved, then all the licenses must be added to the `Third Party Notices.md` file. Simply duplicate the `Component Name/License Type/Provide License Details` section if you have more then one licenes.
+
+    a. Concerning `[Provide License Details]` in the `Third Party Notices.md`, a URL can work as long as it actually points to the reproduced license and the copyright information _(if applicable)_.
+
+1. If your package does not have third party elements, you can remove the `Third Party Notices.md` file from your package.
+
+## Preparing your package for Staging
+
+Before publishing your package to production, you must send your package on the Package Manager's **staging** repository.  The staging repository is monitored by QA and release management, and is where package validation will take place before it is accepted in production.
+## *** IMPORTANT: The staging repository is publicly accessible, do not publish any packages with sensitive material you aren't ready to share with the public ***
+
+
+1. Publishing your changes to the package manager's **staging** repository happens from Gitlab.  To do so, simply setup your project's Continuous integration, which will be triggered by "Tags" on your branches.
+    * Join the **#devs-packman** channel on Slack, and request a staging **USERNAME** and **API_KEY**.
+    * In Gitlab, under the **Settings-> CI/CD -> Secret Variables** section, setup the following 2 project variables:
+        * API_KEY = [your API KEY]
+        * USER_NAME = [your USER NAME@unity]
+    * You're almost done!  To publish a version of your package, make sure all your changes are checked into Gitlab, then create a new tag to reflect the version you are publishing (ex. "v1.2.2"), **the tag will trigger a publish to Staging**. You can view progress you the publish request by switch over to the "CI / CD" part of your project.
+
+1. Do it yourself CI
+
+    If you are using your own CI, it is still recommended that you use the `build.sh` wrapper script that comes with the starter kit, as it handle the installation of the actual CI build scripts for you.
+
+    Instead of calling `npm pack` and `npm publish` in the package root folder in your CI, use 
+    ```
+    ./build.sh package-ci pack --git-head $CI_COMMIT_SHA --git-url $CI_REPOSITORY_URL
+    ```
+    and
+    ```
+    ./build.sh package-ci publish --git-head $CI_COMMIT_SHA --git-url $CI_REPOSITORY_URL
+    ```
+    respectively.
+
+1. Test your package locally
+
+    Now that your package is published on the package manager's **staging** repository, you can test your package in the editor by creating a new project, and editing the project's `manifest.json` file to point to your staging package, as such:
+      ```
+      dependencies: {
+        "com.[YourCompanyName].[sub-group].[your-package-name]": "0.1.0"
+      },
+      "registry": "https://staging-packages.unity.com"
+      ```
+
+## Get your package published to Production
+
+Packages are promoted to the **production** repository from **staging**, described above.
+
+Once you feel comfortable that your package is ready for prime time, and passes validation (Validation Suite), reach out to Unity so your package can be passed along to Release Management, for evaluation.
+
+**Release management will validate your package content, and check that the editor/playmode tests are passed before promoting the package to production.  You will receive a confirmation email once the package is in production.**
+
+**You're almost done!**
+At this point, your package is available on the cloud, but not discoverable through the editor:
+
+1. Contact the Package Manager team to ask them to add your package to the list of discoverable package for the Unity Editor.  All you need to provide is the package name (com.[YourCompanyName].[sub-group].[your-package-name])

+# Unity Services Authentication SDK
+
+This package provides a system for working with the Unity User Authentication Service (UAS), including log-in, player ID and access token retrieval, and session persistence.
+
+## Integration
+
+The Authentication SDK is currently available on the UPM Candidates Repository. You will need to add the UPM Candidates Registry (https://artifactory.prd.it.unity3d.com/artifactory/api/npm/upm-candidates) as a Scoped Registry to your project. Once you have done that, you can add the package `com.unity.services.authentication` with the latest version: `0.5.0-preview`.
+
+Once you have installed the Authentication package, you must link your Unity project to a Unity Cloud Project using the Services window.
+
+The Authentication SDK automatically initializes itself on game start (no prefabs are required, and it will initialize regardless of the current scene), so the only integration steps are to start using the Authentication API in your code. The API is exposed via the `Authentication.Instance` object in the `Unity.Services.Authentication` namespace.
+
+Once the player has been signed in, the Authentication SDK will monitor the expiration time of their access token and attempt to refresh it automatically. No further action is required.
+
+On starting a game you may notice a `UnityServicesContainer` game object is created in the DontDestroyOnLoad area, with an Authentication component. This is how the Authentication SDK hooks onto the Unity lifecycle events that it requires, so if you destroy this object or any of its components, the Authentication system will cease to function. Some values are also cached into `PlayerPrefs`, so clearing all `PlayerPrefs` keys will require the player to sign in again from scratch on their next session rather than being able to continue their current session.
+
+## Public API
+
+### Sign-In API
+
+* `AuthenticationService.Instance.SignInAnonymouslyAsync()`
+    * This triggers the anonymous sign-in processes, which may take some seconds to finish
+	* This requires no parameters
+	* Anonymous sign-in stores the Session Token in Unity PlayerPrefs until an explicit SignOut call is made, so if you simply quit the game before, anonymous sign-in can use the Session Token to let the same anonymous user continue
+	* If you attempt to sign in while already signed in, this method will deliver a warning and set the async operation to fail with `AuthenticationError.ClientInvalidUserState`.
+* `AuthenticationService.Instance.SignInWithSessionTokenAsync()`
+    * This triggers the sign-in of the user with the session token stored on the device.
+    * If there is no cached session token, the async operation fails with `AuthenticationError.ClientNoActiveSession`.
+    * If you attempt to sign in while already signed in, this method will deliver a warning and set the async operation to fail with `AuthenticationError.ClientInvalidUserState`.
+* `AuthenticationService.Instance.SignInWithAppleAsync(string idToken)`
+    * This triggers the sign-in of the user with an ID token from Apple.
+    * Game developer is responsible for installing the necessary SDK and get the token from Apple.
+    * If you attempt to sign in while already signed in, this method will deliver a warning and set the async operation to fail with `AuthenticationError.ClientInvalidUserState`.
+* `AuthenticationService.Instance.SignInWithGoogleAsync(string idToken)`
+    * This triggers the sign-in of the user with an ID token from Google.
+    * Game developer is responsible for installing the necessary SDK and get the token from Google.
+    * If you attempt to sign in while already signed in, this method will deliver a warning and set the async operation to fail with `AuthenticationError.ClientInvalidUserState`.
+* `AuthenticationService.Instance.SignInWithFacebookAsync(string accessToken)`
+    * This triggers the sign-in of the user with an access token from Facebook.
+    * Game developer is responsible for installing the necessary SDK and get the token from Facebook.
+    * If you attempt to sign in while already signed in, this method will deliver a warning and set the async operation to fail with `AuthenticationError.ClientInvalidUserState`.
+* `AuthenticationService.Instance.SignedIn`
+	* This is an event to which you can subscribe to be notified when the sign-in process has completed successfully
+* `AuthenticationService.Instance.SignInFailed`
+	* This is an event to which you can subscribe to be notified when the sign-in process has failed for some reason
+* `AuthenticationService.Instance.SignedOut`
+	* This is an event to which you can subscribe to be notified when the user has been signed out for some reason (either because `AuthenticationService.Instance.SignOut()` was called explicitly, or because of a rejection in an automatic system e.g. a refresh attempt was rejected for having an invalid token)
+* `AuthenticationService.Instance.SignOut()`
+	* This triggers the sign-out process, which includes flushing all cached data and revocation of the access token
+	* If you are not signed in, this method will do nothing
+* `AuthenticationService.Instance.LinkWithAppleAsync(string idToken)`
+    * This function links the current user with an ID token from Apple. The user can later sign-in with the linked Apple account.
+    * Game developer is responsible for installing the necessary SDK and get the token from Apple.
+    * If you attempt to link with an account that is already linked with another user, the async operation to fail with `AuthenticationError.EntityExists`.
+    * If you attempt to sign in while already signed in, this method will deliver a warning and set the async operation to fail with `AuthenticationError.ClientInvalidUserState`.
+* `AuthenticationService.Instance.LinkWithGoogleAsync(string idToken)`
+    * This function links the current user with an ID token from Google. The user can later sign-in with the linked Google account.
+    * Game developer is responsible for installing the necessary SDK and get the token from Google.
+    * If you attempt to link with an account that is already linked with another user, the async operation to fail with `AuthenticationError.EntityExists`.
+    * If you attempt to sign in while already signed in, this method will deliver a warning and set the async operation to fail with `AuthenticationError.ClientInvalidUserState`.
+* `AuthenticationService.Instance.LinkWithFacebookAsync(string accessToken)`
+    * This function links the current user with an access token from Facebook. The user can later sign-in with the linked Facebook account.
+    * Game developer is responsible for installing the necessary SDK and get the token from Facebook.
+    * If you attempt to link with an account that is already linked with another user, the async operation to fail with `AuthenticationError.EntityExists`.
+    * If you attempt to sign in while already signed in, this method will deliver a warning and set the async operation to fail with `AuthenticationError.ClientInvalidUserState`.
+* `AuthenticationService.Instance.IsSignedIn`
+	* Returns true if the player is signed in
+	* Note that the player is still considered signed in until they explicitly call SignOut (or some automatic process causes explicit sign-out), so this will return true even if the access token has expired
+* `AuthenticationService.Instance.PlayerId`
+	* This property exposes the ID of the player when they are signed in, or null if they are not
+* `AuthenticationService.Instance.AccessToken`
+	* Returns the raw string of the current access token, or null if no valid token is available (e.g. the player is signed in but the token has expired and could not be refreshed)
+	* This value is updated automatically by the refresh process, so consumers should NOT cache this value
+
+### Additional Methods
+
+* `AuthenticationService.Instance.SetLogLevel(LogLevel level)`
+	* This enables verbose logging by the Authentication SDK, including exposing the underlying state machine transitions, web request successes and other details that might assist debugging
+	* By default this is set to Errors Only
