+# Emma's Simple Form Field Checker
+
+Compares a PDF form to a list of CS class files to see if all field names are
+present, excluding signature fields.
+
+## Prereqs
+
+Deno >=2.2 (not required if downloading .exe)
+
+## Installation
+
+### Deno install
+
+`deno task install` -> installs as global command `checkfields`
+
+### Compile
+
+`deno task compile` -> compare-form-fields.exe -OR- Download .exe from release
+
+> If you want it to be a global command, create an executables directory and add
+> it to the PATH
+
+## Usage
+
+`checkfields <path to PDF> <comma-separated list of paths to CS class files>`
+-OR- `checkfields` and follow prompts.
+
+### Output
+
+> All form fields present!
+
+-OR-
+
+> The following field names are not present in the CS code
+
+> \<list of missing form fields\>
