+
+Before opening an issue, please check to make sure someone hasn't already opened an issue about it.
+
+## Pull Requests
+
+Before you start working on an issue, please comment on (or create) the issue and wait for it to be assigned to you. If someone has already been assigned but didn't have the time to work on it lately, please communicate with them and ask if they're still working on it. This is to avoid multiple people working on the same issue.

 This is an issue caused commonly by your NGINX configuration. The default file upload size for NGINX is 1MB, you need to add the following in your Nginx sites-available file. ``client_max_body_size SIZE;`` Where "SIZE" is 50M for example for 50MB files.
