-# Install npmts
-First install npmts globally, then install the npmts-g locally.
-
-> **npmts-g* checks if the global version of npmts suffices the modules requirements.
-If not it installs npmts locally in the right version during npm install. 
-
-```sh
-npm install npmts -g # installs npmts globally
-npm install npmts-g --save-dev # installs npmts-g checking tool as devDependency
-```
-
-Then add it to your package.json's script section to trigger a build:
-
-```json
-"scripts": {
-    "test": "(npmts)"
-}
-```
