-The substantial presence test can be a bit confusing. Here's a simple calculator to help you determine whether you pass.
+The IRS uses the [Substantial Presence
+Test](https://www.irs.gov/individuals/international-taxpayers/substantial-presence-test) to determine whether
+a person is a resident for tax purposes. As of the time this calculator was built, the requirements for the
+test are that the person must be physically present in the United States on at lesat:
+
+1. 31 days during the current year, and
+2. 183 days during the 3-year period that includes the current year and the 2 years immediately before that,
+   counting:
+   - All the days you were present in the current year, and
+   - 1/3 of the days you were present in the first year before the current year, and
+   - 1/6 of the days you were present in the second year before the current year.
+
+This can be a bit confusing to calculate, so I've created a tool to help. Your changes will be automatically
+saved to your browser so you can come back later on the same device and get an updated answer if necessary.
