<p>You can use /sandbox/ for writing and testing your own code. Nothing in /sandbox/ will get checked into the repo,
|
|
except files that end in .example (so don't edit or add those files). To get started make a copy of
|
|
index.html.example and rename it to index.html.</p>
|
|
<pre>cp sandbox/index.html.example sandbox/index.html</pre>

<pre>npm run start</pre>
