+Robust PHP math integral solver
+===============================
+
+Get instance of `IntegralSolver` and compute:
+
+```php
+$solver = new IntegralSolver(/* some dependencies */);
+
+// Process simple input:
+$solver->process('1 + x');
+```
+
+All results can be renderer as LaTeX or returned as array of tokens for future computation.
+
+All dependencies you can get by [Package manager](https://github.com/baraja-core/package-manager).
+
+Fully compatible with `Nette 3.0` and `PHP 7.1`.
