title: adjusting settings in liquid shopify theme
body: <p>i have a question about liquid that i imagine someone here will be able to answer. im messing around with my shopify theme and wanted to change the estimated ship date on a per product basis instead of sitewide estimate of like 10-20 days after the current date. i found in my product templete.liquid that it assigns the "estimateStartDate" to equal "settings.delivery_start". "estimateStartDate" is hten references later where it is used in the product description to show estiamted ship date. there is also an assigned estimateenddate.</p>
  
  <p>so my question is: where can i find the code to adjust the dates within this "settings.delivery_start" that the "esitmatestartdate" is set to? ive already made an alternate templete that i will use for the products i want to have these different shipping times. hopefully all this makes sense, im an absoulte ameature in liquid and programming in gneneral. thanks a ton in advance.</p>
