 # Create a Fractal task
 
-Fractal tasks are the core processing units of to build your workflows. Each Fractal task loads the data from one (or many) OME-Zarr(s) and applies processing to them. Fractal tasks are Linux command line executables. For the purpose of this demo, we will look at the Python implementation. You can think of a Fractal task as a Python function that knows how to process an OME-Zarr image and save the results back into that OME-Zarr image. With a bit of syntax sugar, this becomes a Fractal task you can then run from the web interface. To understand the types of tasks, their API & how they provide information to Fractal server, check out the [V2 Tasks page](https://fractal-analytics-platform.github.io/version_2/tasks/).
