+Note: This install guide has been generously contributed by the Mattermost community. It has not yet been tested by the core. We have [an open ticket](https://github.com/mattermost/platform/issues/1185) requesting community help testing and improving this guide. Once the community has confirmed we have multiple deployments on these instructions, we can update the text here. If you're installing on Debian anyway, please let us know any issues or instruciton improvements? https://github.com/mattermost/platform/issues/1185
