+# Welcome to Pixel Streaming contribution guide
+
+First and foremost, thank you for your time and contribution to Pixel Streaming!
+
+We are proud and excited to be a part of a passionate community that continuously helps us improve Pixel Streaming 🎉
+
+If you are not familiar with contributing on GitHub, have a look at the [official documentation](https://docs.github.com/get-started) to learn more about repositories structure, forks, branches, commits, issues, and PRs.
+
+### Code of conduct
+
+Please remain patient, courteous, and professional at all times. Any form of spam, abuse, or discrimination will not be tolerated.
+
+## Getting started
+
+### Creating issues
+
+If you have encountered a bug, have suggestions for our documentation or infrastructure, or would like to propose a feature that could enhance Pixel Streaming in various use case scenarios, you can raise this with us by creating a new issue.
+1. First, search all open and closed issues [here](https://github.com/EpicGames/PixelStreamingInfrastructure/issues?q=is%3Aissue+) - your issue may have already been discussed or addressed.
+2. If your issue doesn't exist, open a new issue [here](https://github.com/EpicGames/PixelStreamingInfrastructure/issues/new/choose) by selecting a bug or feature request.
+3. Make sure to fill in the template as much as possible; any information you can provide, such as repro steps, crash stacks, screenshots, etc., can help us triage and fix the problem as quickly as possible.
+4. Keep an eye on the status of your issue; our developers or other users might reach out with requests for more information. If this happens, issues that have not received a response in over 30 days will be automatically closed.
+5. Be patient while waiting on a resolution; we prioritize the issues internally and some less critical features (however much we'd love to implement them!) will take a backseat to more pressing priorities, so some issues can take a while to get resolved.
+
+### Creating pull requests (PR)
+
+If you have a solution to a problem you've encountered or to any other open issue, you can create a pull request with your changes.
+1. Fork the repo and branch off of the `main` branch in your fork.
+2. Implement your changes in your branch and make sure your commits are Verified! Signed commits are required for merging! [Github Signing Documentation](https://docs.github.com/en/authentication/managing-commit-signature-verification/about-commit-signature-verification)
+3. Do as much testing as you can, and when you are happy, tidy up your work and commit the update.
+4. Create a [pull request](https://github.com/EpicGames/PixelStreamingInfrastructure/pulls) and don't forget to link it to an issue if there's an existing one. Add as much information as possible to your PR: describe the problem your change solves, mention any testing you have done and attach any relevant documents and screenshots.
+5. If your are contributing a PR for a new feature, we strongly encourage you to accompany it with relevant documentation and a detailed description of the tests you have done. PRs that don't have this information may take a long time to be addressed, since our team will have to do the testing.
+6. If your PR is good to go, we will merge it in. Woohoo! Thank you for your time and efforts! 🎉
+7. Keep a close eye on your PR - quite often, our developers will review your PR and leave comments; we might request some minor code changes and modifications, style unification, or leave any general comments and questions that are preventing us from merging the PR.
+8. If we do not hear from you after requesting more information within 30 days, the PR will auto-close. In this case, we might elect to open our own PR and re-use some of the changes that you proposed, supplemented with anything else that was required to be added in your original PR.
+9. If your PR fixes a problem in the previous [still-supported UE branches](https://github.com/EpicGames/PixelStreamingInfrastructure#versions), feel free to add the `auto-backport` and `auto-backport-to-UEX.X` labels. You'll need to add a `auto-backport-to-UEX.X` label for each branch you wish your change to be merged back to. Note that if a change to any of the previous branches is not trivial and requires a lot of testing and compatibility checks, we might elect to close it if we do not think that it brings enough value to the branch.
+
+### Other ways to contribute
+
+- Keep an eye on our repo and stay active on existing issues and PRs; you can help by adding informative comments to the discussions, additional repro steps, repros in different environments, or any suggestions as to what could be causing the issue and how it could be solved.
+- Work on [issues labeled for community](https://github.com/EpicGames/PixelStreamingInfrastructure/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22). We specifically created this label to mark issues that we would love the community to help us with.
+- Create documentation for undocumented features. Please open an issue first, so our developers can provide you with some guidance.
+- Write more unit test coverage.
+- Document functions in the public API that are not documented.
+- Write new frontend implementations using another web framework, e.g. Angular, Vue, etc.
+- Perform QA on different engine versions, particularly previews, and create issues based on the bugs that you have found.
+
+## Coding style
+ - TypeScript should be used over JavaScript.
+ - All TypeScript should adhere to the following [linting rules](https://github.com/EpicGames/PixelStreamingInfrastructure/blob/master/Frontend/library/.eslintrc.js).
+ - Names should follow US English spelling.
+ - All public functions/API should have comments.
+ - Code formatting should adhere to the following [whitespace and indentation rules](https://github.com/EpicGames/PixelStreamingInfrastructure/blob/master/Frontend/library/.prettierrc.json).
+ - All new features should have accompanying unit tests and documentation when they are submitted.
+ - Prefer early returns in `if` statements to decrease indentation.
+ - Prefer functions to not exceed ~20 lines.
+ - Prefer comments in longer functions.
+ - Prefer verbosity over syntactic sugar.
+ - Prefer exporting a minimal public API surface for iteration and support reasons.
+ - Try not to exceed three levels of nesting in a function.
+
+## Documentation style
+All documentation should be written in US English and follow correct grammar and spelling. Endeavour to lay out the document in a logical fashion with headings, lists, and bullet points where appropriate.
+
+Documentation should be broken up into separate `.md` files per directory, ideally with a `readme.md` file in the root of each top-level directory for a component to explain it. Where appropriate, these documentation pages should be linked to a table of contents in the relevant part of the repository.

+# Security Guidelines
+
+To enhance the security of your Pixel Streaming deployments, it is wise to implement additional measures for protection. This documentation page aims to provide you with valuable recommendations and suggestions to bolster the security of your deployments. By following these guidelines, you can significantly enhance the overall security posture and safeguard your Pixel Streaming environment effectively.
+
+## Tips to Improve Security
+Please note that implementing the following suggestions may introduce additional setup complexity and could result in increased latency.
+
+1. **Isolate Unreal Engine Instance:** Avoid deploying the Unreal Engine instance on a cloud machine with a public IP. Instead, only allowlist the necessary servers, such as the signalling and TURN servers, to communicate with the UE instance.
+
+2. **Route Media Traffic through TURN Server:** For enhanced security, enforce routing all media traffic through the TURN server. By doing so, only the TURN server and signalling server will be permitted to communicate with the UE instance. Keep in mind that this approach may introduce some additional latency.
+
+3. **Secure TURN Server with User Credentials:** Configure the TURN server with a user database and assign unique credentials to each user. This additional security layer prevents unauthorized access to the relay. By default, Pixel Streaming employs the same TURN credentials for every session, which may simplify access for potential attackers.
+
+4. **Avoid Storing Important Credentials in the UE Container:** As a precautionary measure, refrain from storing any critical credentials or sensitive information within the UE container. This practice helps maintain a higher level of security.
+
+5. **Disable Pixel Streaming Console Commands:** Pixel Streaming ensures that all media traffic is encrypted end-to-end, guaranteeing secure communication. However, note that Pixel Streaming allows users to send commands to the UE instance if enabled. To eliminate this possibility, launch without the `-AllowPixelStreamingCommands` flag.
+
+6. **Separate TURN and Signalling Servers:** It is recommended to avoid colocating the TURN and signalling servers with the UE instance on the same IP or virtual machine (VM). This enables you to configure separate ingress/egress security policies for each server, allowing flexibility in defining the desired level of strictness or looseness. For example, the TURN server can have more relaxed policies while the UE instance can have stricter ones.
+
+By following these tips, you can enhance the security of your Pixel Streaming setup and mitigate potential risks.

Frontend/Docs/Customizing Player Input Options.md

@@ -9,6 +9,7 @@ The following options are available in the frontend library to customize input:
 |   HoveringMouseMode  |  false  | Determines whether or not the video element captures and locks the mouse when the player interacts with the widget. When enabled, the mouse cursor hovers over the player widget without interacting with it. In order to send the mouse movements to the input controller of the Unreal Engine application, the user needs to click and hold the left button of the mouse. Otherwise, clicking on the player widget causes it to capture and lock the mouse cursor. Any further movements of the mouse are passed immediately to the input controller in the Unreal Engine application. This typically allows the user to move and rotate the camera by simply dragging the mouse. To release the cursor from the control of the player widget, the user can press the **Esc** key. |
 |  SuppressBrowserKeys |   true  | When this setting is enabled, the player widget will intercept function keys (**F1** to **F12**) and the **Tab** key, and pass those keypress events through to the Unreal Engine application rather than allowing the browser to process them normally.| This means, for example, that while this setting is active, pressing **F5** will not refresh the player page in the browser. Instead, that event is passed through to the Unreal Engine application, and has its usual function of switching the view to visualize shader complexity.
 | FakeMouseWithTouches |  false  | When this option is enabled and the user is viewing the stream on a device with a touch screen such as a smartphone or tablet, this setting causes single-finger touch events to be interpreted by the Unreal Engine application as mouse clicks and drag events. Enabling this setting can provide users on mobile devices with the ability to partially control your Unreal Engine application, even when the application's input controller does not specifically handle touch input events. |
+|   UseMic  |  false  | Indicates whether or not the stream should be created with a microphone track which is sent to the UE application. This microphone track can be listened to using the [`UPixelStreamingAudioComponent`](https://docs.unrealengine.com/5.0/en-US/API/Plugins/PixelStreaming/UPixelStreamingAudioComponent/). If this flag is enabled, a microphone audio track is created (if the browser settings allow for it) and is actively sending audio. For saving bandwidth or other functionality, it's possible to mute the microphone track by calling `PixelStreaming`'s `muteMicrophone`, and later re-enable it with `unmuteMicrophone`. If the `PixelStreaming` object was created without this flag, it's possible to enable it later by calling `unmuteMicrophone(true)`, which will use the `forceEnable` parameter to add the track and trigger a full reconnection (this is a heavier operation that takes a while). |
 
 When creating a frontend implementation, these options are visible via the [`Config`](/Frontend/library/src/Config/Config.ts) object required in order to create a [`PixelStreaming`](/Frontend/library/src/PixelStreaming/PixelStreaming.ts) stream for your frontend application. Simply set the values you want before initializing the stream object.

Frontend/Docs/Using the Microphone Feature.md

@@ -0,0 +1,48 @@
+## Microphone feature summary
+
+In its current state, the microphone feature in Pixel Streaming is designed to pass the streamer’s microphone input audio from Pixel Streaming to Unreal Engine. The WebRTC audio stream is not exposed nor further handled inside the engine, so any custom use of the audio stream will require significant modifications by the user.
+
+## Enabling microphone input for Pixel Streaming in UE projects
+
+Once you’ve enabled the Pixel Streaming plugin in your project, you’ll need to add the `Pixel Streaming Audio` component to your scene. It can be attached to any actor or asset in the scene, following these steps:
+
+- Select any enabled actor or asset in your scene;
+- Click the *Add* button, located in its details panel;
+- Type *Pixel Streaming Audio* in the search bar and click the matching component:
+
+<p align="center">
+    <img src="Resources\Images\add-pixel-streaming-to-actor.png" alt="Add component to actor">
+</p>
+
+Once the component has been added, you can adjust its settings and specify a player or streamer ID to listen to, if you wish. The default configuration will be listening to the first peer it can hear and should be suitable for most basic use cases:
+
+<p align="center">
+    <img src="Resources\Images\settings-pixel-streaming-audio.png" alt="Component configuration">
+</p>	
+
+No more setup is required on the UE side, so the project is now ready to be packaged or used standalone.
+
+## Enabling microphone in Pixel Streaming frontend
+
+Launch Pixel Streaming and click the cog icon to open the stream settings, where you can enable the microphone toggle. Make sure to restart the stream to apply the changes:
+
+<p align="center">
+    <img src="Resources\Images\mic-toggle.png" alt="Component configuration">
+</p>	
+
+*Note:* Alternatively, you can enable the microphone by adding `?UseMic=true` to the url. You’ll still need to refresh the page for the change to take effect.
+
+When doing this for the first time, your browser will likely ask your permission to use the microphone on this page, which you need to allow. Some browsers and firewalls may automatically block it, so you will need to create permission rules in your browser settings.
+
+You are ready to roll! Connect to the stream and speak into the microphone. If everything has been set up correctly, your microphone input will be passed to UE and played back to you by Pixel Streaming, so you will hear yourself.
+
+*Note:* The above steps will not work without the `Pixel Streaming Audio` component set up in your project. If you don’t hear any playback, double check your project for the appropriate component.
+
+## Tips on handling the microphone WebRTC stream further
+
+As mentioned earlier, the microphone audio stream isn’t handled further after it’s passed to UE. You might want to use it in custom ways, for example, feed it back to Pixel Streaming so you could hear the other players, or pass it to another plugin to create a voice chat. Here are some tips to help you get started:
+
+- You can choose to use a voice chat plugin, whose audio data goes through the UE audio system, which will be automatically picked up by Pixel Streaming.
+- If you would like to pass the data elsewhere, e.g. to your custom plugin, you'll need to create your own audio sink, see more information [here](https://github.com/EpicGames/UnrealEngine/blob/5ca9da84c694c6eee288c30a547fcaa1a40aed9b/Engine/Plugins/Media/PixelStreaming/Source/PixelStreaming/Public/IPixelStreamingStreamer.h#L220).
+- You can implement Pixel Streaming audio mixer and plug the audio from your voice plugin into it. [Here](https://github.com/EpicGames/UnrealEngine/blob/release/Engine/Plugins/Media/PixelStreaming/Source/PixelStreaming/Private/AudioInputMixer.h) is a good jumping point.
+- Both camera and microphone access will be blocked on *insecure origins* (in effect since Chrome 47), so make sure to use HTTPS for production. This is not required for local use, e.g. during development.
