== How to create /sandbox and /testcases subpages ==
# Suppose your template is named <code>Template:X</code>. Create a subpage with the name <code>Template:X/sandbox</code>. If the main template is using the {{tl|documentation}} template, you can do this from a link at the bottom of the blue documentation box on the template main page. Or you can type it into the search box, or directly into the URL bar of your browser. Note that "/sandbox" is all lowercase.
# Copy the entire contents of the main template, including <code><nowiki><noinclude></nowiki></code> tags and the {{tl|documentation}} template if present, paste it into the edit window of the /sandbox subpage, and save the page. Your edit summary should be something like "<code><nowiki>create sandbox version of [[Template:X]]"</nowiki></code>.
#* Note: if you use the "mirror" link at the bottom of the blue documentation box, tags like <code><nowiki><noinclude></nowiki></code>, and their contents, will be missing. It's best just to copy and paste manually.
# Create another subpage with the name <code>Template:X/testcases</code>. This page is only linked from the bottom of the blue documentation box if it actually exists, so to create it you will need to create it by typing the page name into the search box or into the URL bar of your browser. Again, note that "/testcases" is all lowercase, and all one word.
