Looks good, I added some small points, and added a version alert.
Still needs precice/precice#2386 to be merged.
| When using a `"spread"` mapping, the 1D quantity is distributed over the 3D interface using the `spread-profile`, which defines how the value varies radially across the circular interface. It can either be `"uniform"`, where the same value is applied to all interface vertices; or `"parabolic"`, in which a parabolic profile is applied (maximum at the centerline, decreasing to zero at the wall). | ||

| Since the 1D participant likely computes average quantities, e.g., the average pressure and velocity in a pipe, a velocity profile has to be assumed in order to convert data between the 1D and 3D participant for the axial mapping. Currently, a laminar flow profile is imposed by default, but different profiles might be supported in the future. | ||

Since the option is not yet in a released version of preCICE, let's add a version note:

| The `spread-profile` option is currently only available in the `develop` branch of preCICE. Until v3.3.0, there was no option to switch off the parabolic profile. | |
