# Hello, and welcome to makefile basics. | |

# You will learn why `make` is so great, and why, despite its "weird" syntax, | |

# programs. | |

# Once you're done here, go to | |
# http://www.gnu.org/software/make/manual/make.html | |
# to learn SOOOO much more. |

Vue.js is an amazing framework, which can be as powerful as Angular or React, the two big heavy hitters in the world of front-end frameworks.
