We need to re-write

team-compass/docs/practices/funding.md

Lines 24 to 31 in 90ed3a2

	## How to get reimbursed from NumFocus
	If you spend money that should be reimbursed from a NumFocus grant or account, fill out the typeform below to submit the reimbursement.
	```{button-link} https://numfocus.typeform.com/to/O4K2Zol6
	:color: primary
	File a reimbursement
	```

as The Linux Foundation is the fiscal sponsor for Jupyter.
