-Every program executed in `console` has these `environment` variables:
+### Install
+
+`Terminal` disabled and not installed by default. To use it you should install [gritty](https://github.com/cloudcmd/gritty "Gritty") with:
+
+```sh
+npm i gritty -g
+```
+
+And then set the path of a terminal with:
+
+```sh
+cloudcmd --terminal --terminal-path `gritty --path` --save
+```
+
+### Windows
+
+On Windows you need to install `windows-build-tools` before:
+
+```sh
+npm install --global windows-build-tools
+```
+
+Then get path of a `gritty` with:
+
+```sh
+gritty --path
+```
+It will returns something like:
+
+```sh
+C:\Users\coderaiser\AppData\Roaming\npm\node_modules\gritty
+```
+
+Set this path as `--terminal-path` with:
+
+```sh
+cloudcmd --save --terminal --terminal-path "C:\Users\coderaiser\AppData\Roaming\npm\node_modules\gritty"
+```
+
+After that you can use `terminal` in the same way as a `console`.
