| Hooks let you run custom commands at specific points in your application’s lifecycle during [`build`, `deploy`](/learn/overview/build-deploy.html), or `runtime`. They’re essential for setting up your app, managing graceful shutdowns, or preparing instances to handle traffic in autoscaling environments. |

This reads weird to me. it's like it's missing some word after runtime :)

Hi @ricardokirkner i've adjusted this sentence so it reads a bit better.
| |------|------|-----------|--------------| | ||
| | **pre_start** | string | No | Runs just before `start`. Useful for short setup actions that must run per instance, such as moving cache files or setting permissions. | | ||
| | **start** | string | Yes | The main command that launches your app. If it terminates, {{% vendor/name %}} restarts it immediately. | | ||
| | **post_start** | string | No | Runs after the `start` command but before the container is added to the router. This lets you complete warm-up tasks before the app starts handling traffic. | |

We should mention here that if post_start is defined, instances won't start getting traffic routes to them until that script finishes successfully.

This is important to the customer experience—is this a blocking hook or not?
Could this be addressed by a Boolean column such as "Freezes/Holds Requests"?

Hi @ricardokirkner @tylers-username i've added a boolean column to address whether its a blocking or non blocking hook
