 FixCors es una herramienta simple que te ayuda a solucionar los errores de CORS (Cross-Origin Resource Sharing) que pueden ocurrir al consumir APIs desde diferentes dominios. Con FixCors, podrás:
 
+- Consumir una API y evitar los errores de cors en el navegador
+
+- Evitar instalar o realizar configuraciones extrañas
+
+
+## Como Usar FixCors
+
+Para usar FixCors es muy facil.
+
+Coloca lo siguiente antes de la url de la API que deseas consumir
+
+```html
+https://fixcors.site/?api=
+
+```
+La url completa quedara de la siguiente manera
+
+```html
+https://fixcors.site/?api=https://apps.bolchile.com/api/v1/dolarstatd2
+
+```
+Asi de simple
