Sharelatex

Sorry to be such a noob, can you give directions on using ShareLatex https://www.sharelatex.com? I uploaded the coloremoji.sty into a document but then I get this as output:

Hello,[U+FFFD][U+FFFD].

Here is my ShareLatex document. Note I commented out one line since when it was there I only got Hello

Hello, .

\documentclass{article}
%\usepackage[utf8]{inputenc}
\usepackage{coloremoji}
\begin{document}
Hello, 🌎.
\end{document}
