How can I know what to do without installing the quickstart package?

Hi,
I would like to know something…
after installing your quickstart template I found that you are adding some codes in the menus, pages etc…

If you didn’t added those codes, how can I know what and where to add it without installing the quickstart package?

and just to be clear with my question I will give you 2 samples:

SAMPLE A

inside the JM Mega Mene > Breakfast menu > Submenu Content > Custom block

you wrote:
{{block type="joomlart_jmproducts/list" name="home.jmproducts.simplelist" template="joomlart/jmproducts/simplelist.phtml" }}

If I didn’t use your quickstart package, how can I know that I need to write it??? what else can I write there? what are all the options I have?

SAMPLE B

go to --> CMS > Pages > Home page > Content Tab

you wrote:
{{block type="joomlart_jmproducts/list" name="home.jmproducts.list" template="joomlart/jmproducts/list.phtml" }}

and inside the design tab you wrote:
<!-- Bottom Spotlight -- topsl -->
<reference name="topsl">
<block type="cms/block" name="position-1">
<action method="setBlockId"><block_id>position-1</block_id></action>
</block>
<block type="cms/block" name="position-2">
<action method="setBlockId"><block_id>position-2</block_id></action>
</block>
<block type="cms/block" name="position-3">
<action method="setBlockId"><block_id>position-3</block_id></action>
</block>
<block type="cms/block" name="position-4">
<action method="setBlockId"><block_id>position-4</block_id></action>
</block>
<block type="cms/block" name="position-5">
<action method="setBlockId"><block_id>position-5</block_id></action>
</block>
</reference>
<!-- Bottom Spotlight -- topsl -->
<reference name="left">
<block type="cms/block" name="left-banner">
<action method="setBlockId"><block_id>left-banner</block_id></action>
</block>
<block type="joomlart_jmproductsspotlight/list" name="jmproductsspotlight" template="joomlart/jmproductsspotlight/list.phtml" />
</reference>
<reference name="right">
<remove name="catalog.compare.sidebar" />
<remove name="right.poll" />
<remove name="cart_sidebar" />
<remove name="paypal.partner.right.logo" />
<remove name="right.reports.product.viewed" />
<remove name="wishlist_sidebar" />
<remove name="sale.reorder.sidebar" />
<block type="cms/block" name="block-welcome" >
<action method="setBlockId"><block_id>block-welcome</block_id></action>
</block>
<block type="cms/block" name="block-twitter" >
<action method="setBlockId"><block_id>block-twitter</block_id></action>
</block>
<block type="cms/block" name="block-contact" >
<action method="setBlockId"><block_id>block-contact</block_id></action>
</block>
</reference>
