+## Sobre PageTop
+
+[PageTop](https://docs.rs/pagetop) es un entorno de desarrollo que reivindica la esencia de la web
+clásica para crear soluciones web SSR (*renderizadas en el servidor*) modulares, extensibles y
+configurables, basadas en HTML, CSS y JavaScript.
+
+
+# 🚧 Advertencia
+
+`PageTop` es un proyecto personal que hago por diversión para aprender cosas nuevas. Está en
+desarrollo activo, su API es inestable y está sujeta a cambios frecuentes. No recomiendo su uso en
+producción, al menos hasta liberar la versión **1.0.0**.
