Think of a classic family cookbook filled with traditional soup recipes. One afternoon, you decide to

experiment by adding unique local spices to standard tomato soup recipe. If you write your changes directly

onto original page over old text, original instructions are lost forever. Next time book publisher sends

updated version of cookbook, your handwritten notes disappear completely. Smart approach is writing your

special spice twist on separate sticky note, pasting it gently over original recipe page. PrestaShop override

system uses this exact sticky-note philosophy for website code modification.

Core software contains thousands of factory-made files ensuring online store functions correctly.

Sometimes, specific business requirements demand unique changes, such as modifying tax calculation

steps or altering checkout behaviors. Directly editing original platform files is dangerous practice. When

official software update arrives to fix security bugs, all custom edits get wiped out instantly, breaking online

store functionality.

Override feature creates a safe playground. It tells system to look into a special custom folder before

executing standard code. If custom file exists there, system reads your custom instructions instead of

default ones. This brilliant separation keeps core software pristine, untouched, ready for seamless official

upgrades. It offers professional developers freedom to bend platform behavior to specific needs while

keeping entire website structure safe, stable, future-proof for years to come.
