-# Ubuntu Builds
-
-Cesium can be build as desktop application for Ubuntu, or as App on Ubuntu phone. Such builds use cross-architecture [click targets](https://developer.ubuntu.com/en/phone/apps/sdk/tutorials/click-targets-and-device-kits/) and the specific Apache Cordova platform `ubuntu`.
-
-## Prerequisites
-
-### Install the development environment
-
-Follow all the steps defined in the [Development guide](./development_guide.md).
-
-After that you should be able to start the application using `npm start`, and to test it.
-
-## Install Ubuntu SDK
-
-Source documentation [here](https://developer.ubuntu.com/en/phone/platform/sdk/installing-the-sdk/) and [here](https://cordova.apache.org/docs/en/latest/guide/platforms/ubuntu/index.html)
-
-Install the SDK :
-
-```bash
-sudo add-apt-repository ppa:ubuntu-sdk-team/ppa
-sudo apt update
-sudo apt install ubuntu-sdk
-```
-
-Install "click" packaging tools:
-
-```bash
-sudo apt-get install click cmake libicu-dev pkg-config devscripts qtbase5-dev qtchooser qtdeclarative5-dev qtfeedback5-dev qtlocation5-dev qtmultimedia5-dev qtpim5-dev libqt5sensors5-dev qtsystems5-dev
-
-```
-> Alternatively (not tested):
-> `sudo click chroot -a armhf -f ubuntu-sdk-15.04 install cmake libicu-dev:armhf pkg-config qtbase5-dev:armhf qtchooser qtdeclarative5-dev:armhf qtfeedback5-dev:armhf qtlocation5-dev:armhf qtmultimedia5-dev:armhf qtpim5-dev:armhf libqt5sensors5-dev:armhf qtsystems5-dev:armhf`
-
-
-
-## Add Ubuntu platform to the Ionic project
-
-```bash
-cd cesium
-ionic platform add ubuntu
-```
-
-## Running Ubuntu SDK IDE (optional)
-
-To debug or configure the Ubuntu builds easily, you can use the Ubuntu SDK IDE.
-
-```bash
-ubuntu-sdk-ide
-```
-
-> Note: Before launching the IDE, make sure your user has the unix group `lxd`. If not, simply execute this command:
-> `sudo usermod -a -G lxd mon_user`
-
-
-## Build Debian package
-
-Cesium can be built on a `amd64` architecture.
-
-1. Generate the `click` source code:
-
-```bash
-cd cesium
-ionic build ubuntu --release
-```
-
-2. Then build the project:
-
-```bash
-cd platforms/ubuntu/native/cesium
-debuild
-```
-
-This should generate the `.deb` in directory `<cesium>/platforms/ubuntu/native`.
-
-> This step will required a valid (and installed) GPG key, to sign the `.deb` file.
-> The key should match the `author` field of the file `<cesium>/config.xml`.
-> To be able to your own GPG key, change the author.
-
-### Build for Ubuntu Phone
-
-Cesium can be built on a `armhf` architecture.
-
-Install `armhf` build platform:
-
-```bash
-sudo click chroot -a armhf -f ubuntu-sdk-15.04 create
-```
-
-Then install some dependencies inside the `armhf` chroot:
-
-```bash
-sudo click chroot -a armhf -f ubuntu-sdk-15.04 install cmake libicu-dev:armhf pkg-config qtbase5-dev:armhf qtchooser qtdeclarative5-dev:armhf qtfeedback5-dev:armhf qtlocation5-dev:armhf qtmultimedia5-dev:armhf qtpim5-dev:armhf libqt5sensors5-dev:armhf qtsystems5-dev:armhf
-```
-
-Build the phone application
-
-```bash
-cd cesium
-ionic build ubuntu --device
-```
-
-> To test your application on phone, execute :
-> `ionic run ubuntu --device`
-
-
-
-## Publishing to Ubuntu App Store
-
-Follow steps on https://developer.ubuntu.com/en/publish/
