Mirror is built [and tested](https://www.youtube.com/watch?v=mDCNff1S9ZU) for **MMO Scale** Networking by the developers of [uMMORPG](https://www.assetstore.unity3d.com/#!/content/51212), [uSurvival](https://www.assetstore.unity3d.com/#!/content/95015) and [Cubica](https://cubica.net).
Mirror is optimized for **ease of use** and **probability of success**. Projects that use Mirror are small, concise and maintainable. uMMORPG was possible with <6000linesofcode.Weneededanetworkinglibrarythatallowsusto [launch our games](https://mirror-networking.com/showcase/),period.
With Mirror, the **Server & Client are ONE** project _(hence the name)_. Instead of having one code base for the server and one for the client, we simply use the same code for both of them.
If you are migrating from UNET, then please check out our [Migration Guide](https://vis2k.github.io/Mirror/General/Migration). Don't panic, it's very easy and won't take more than 5 minutes.
For the latest improvements, [Download Mirror](https://github.com/vis2k/Mirror/releases) directly from this repository and extract it in your Assets folder.
For a fully polished, complete project example, consider [uMMORPG](https://www.assetstore.unity3d.com/#!/content/51212) or [uSurvival](https://www.assetstore.unity3d.com/#!/content/95015).

If you want to contribute, always follow the [KISS](https://en.wikipedia.org/wiki/KISS_principle) principle. Everything needs to be **as simple as possible**. As result, the code will be stable, easy to understand, easy to modify and easy to maintain 5 years from now when our games are still running.
Pull Requests for bug fixes are always highly appreciated. New features will be considered very carefully and will only be merged if they are the most simple solution to the given problem.
