-```
- sudo apt-get install git wget curl unzip build-essential software-properties-common ruby ruby-dev ruby-ffi gcc make
-```
+1. Installing build tools:
+ ```bash
+ sudo apt-get install git wget curl unzip build-essential software-properties-common ruby ruby-dev ruby-ffi gcc make
+ ```
- - Installing [nvm](https://github.com/nvm-sh/nvm)
-```
- wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.1/install.sh | bash
-```
+2. Installing node.js v10 :
-If you are using fish shell, there is a [dedicated plugin](https://github.com/jorgebucaran/fish-nvm).
+ * First, install [nvm](https://github.com/nvm-sh/nvm) (Node Version Manager) :

+ ```
-> To remind: check that your command line is configured:
-> - You must place yourself in the directory of the application: `cd cesium`
-> - and be configured for NodeJs v6: `nvm use 6` (please check using the command `node --version`)

+
+Cesium can be build:
+- [as an unhosted web applicationa](build_web.md);
+- [for Android](build_android.md);
+- [for iOS](build_ios.md);
+- [as a Web extension](build_web_extension.md) for Mozilla Firefox or Chrome/Chomium;
+- [as a Desktop application](build_desktop.md) for Linux (`.deb`), Windows and MacOSx;
