How to understand the main structure of the CLM model？

We are trying to develop a CLM coupled hydrological model, and requires an understanding of the CLM model structure.

Are there any documents or materials that introduce the structure of the CLM model.
Like the CLM model flowchart, the structure of subroutine calls, and so on.

Additionally, how can a novice quickly understand the main structure of the CLM model?
If there are any other ways to understand the main structure of the CLM model besides reading the code of the model.

thanks all.

Thank you, slevis.

We have some experience in land surface biogeochemisty and biogeophysics processes.
But now I have doubts about the connection between these processes,
especially how to connect them in the model structure.

Can you give me some further suggestions on understanding the relationship between land surface processes in the model?

Besides the technical note, other resources are the CLM5 overview paper:

and maybe the CLM driver code that contains the sequence of most of the subroutine calls which can be found at:

src/main/clm_driver.F90
