# Conditions

Nodes that control how your workflow progresses with flow logic nodes.

Using these nodes you can:

* **Branch** based on conditions (e.g. if/else, switch)
* **Merge** multiple paths back together
* **Loop** through items in a list with `for each`
* **Wait for human input** before continuing (e.g. request manual approval, wait for user action)
* **Stop** or pause execution
* **Jump** to a specific step
