+<details>
+<summary>Extra Info & Rant</summary>
+
+Previously called [UniFi Controller](https://github.com/linuxserver/docker-unifi-controller)
+
+Ubiquiti morons decided to change the name to UniFi Network Application.
+Then also tried to go for name UniFi Network Server with claim that it is for 
+selfhosted version, when not on their hardware. In docks even in downloads they
+mostly use the `application` name.<br>
+Though love that inside the webgui version its just `Network 8.0.28`
+
+With this name change, linuxserver.io also changed the deployment so that
+mongo database is now a separate container.<br>
+Would not be a big issue, if mongo would not [suck big time](https://github.com/docker-library/mongo/issues/174)
+at initiating databases in new deployments, making it unnecessary complicated.
+Or if linuxserver.io could make a decision and write
+[cleaner instructions](https://github.com/linuxserver/docker-unifi-network-application/issues/13)
+instead of trying to teach to fish.<br>
+Also linuxserver.io official stance is to use older version of mongo 3.6 - 4.4<br>
+Raspberry Pi users need to go for that 3.6
+
+Big help to get this going cleanly was also [this repo](https://github.com/GiuseppeGalilei/Ubiquiti-Tips-and-Tricks),
+from [this](https://www.reddit.com/r/Ubiquiti/comments/18stenb/unifi_network_application_easy_docker_deployment/)
+reddit post.<br>
+First time Ive seen configs used in compose this way, saved bother of doing
+a separate `mongo-init.js` file that for some reason did not work for me.
+I improved it a bit by using variables.
