+> First-order logic with integer arithmetics
+
+This crate provides an abstract syntax tree for first-order formulas with integer arithmetics.
+
+## Supported Formulas
+
+- Booleans values (`true` and `false`)
+- predicates
+- negated formulas
+- comparisons of terms (<, ≤, >, ≥, =, ≠)
+- implications and biconditionals
+- conjunctions and disjunctions of formulas
+- existentially and universally quantified formulas
+
+## Supported Terms
+
+- Boolean values (`true` and `false`)
+- integers
+- strings
+- special integers (infimum and supremum)
+- symbolic functions
+- variables
+- binary operations (addition, subtraction, multiplication, division, modulo, exponentiation)
+- unary operations (absolute value, numeric negation)
