+# Tarjeta de estadísticas de GitHub
+
+Copia y pega esto en el contenido de tu README.md y listo. ¡Simple!
+
+Cambia el valor `?username=` al nombre de tu usuario de GitHub.
+
+```md
+[![Anurag's github stats](https://github-readme-stats.vercel.app/api?username=anuraghazra)](https://github.com/anuraghazra/github-readme-stats)
+```
+
+_Nota: las clasificaciones se calculan basándose en las estadísticas del usuario. Ve [src/calculateRank.js](./src/calculateRank.js)._
+
+### Ocultar estadísticas individualmente
+
+Para ocultar alguna estadística específica, puedes utilizar el parámetro `?hide=` con un arreglo de items que quieras ocultar.
+
+> Opciones: `&hide=["stars","commits","prs","issues","contribs"]`
+
+```md
+![Anurag's github stats](https://github-readme-stats.vercel.app/api?username=anuraghazra&hide=["contribs","prs"])
+```
+
+### Mostrar íconos
+
+Para habilitar los íconos, puedes utilizar `show_icons=true` como parámetro, de esta manera:
+
+```md
+![Anurag's github stats](https://github-readme-stats.vercel.app/api?username=anuraghazra&show_icons=true)
+```
+
+### Temas
+
+Puedes personalizar el aspecto de la tarjeta sin realizar ninguna [personalización manual](#personalización) con los temas incorporados.
+
+Utiliza el parámetro `?theme=THEME_NAME`, de esta manera:
+
+```md
+![Anurag's github stats](https://github-readme-stats.vercel.app/api?username=anuraghazra&show_icons=true&theme=radical)

+# Pins extra de GitHub
+
+Los pins extra de GitHub te permiten anclar más de 6 repositorios en tu perfil utilizando el archivo README.md.
+
+¡Bien! Ya no estás limitado a 6 repositorios anclados.

+
+### Pequeño consejo (alinear las tarjetas de repositorios)
+
+Usualmente no serías capaz de alinear las imágenes una al lado de otra. Para lograrlo, puedes realizar esto:
+
+```md
+<a href="https://github.com/anuraghazra/github-readme-stats">
+  <img align="left" src="https://github-readme-stats.vercel.app/api/pin/?username=anuraghazra&repo=github-readme-stats" />

+```
+
+## Despliega tu propia instancia de vercel
+
+Desde que la API de GitHub permite solo 5 mil peticiones por hora, es posible que mi `https://github-readme-stats.vercel.app/api` pueda llegar al límite. Si lo alojas en tu propio servidor de Vercel, no tendrás que preocuparte de nada. ¡Clickea en el botón "Deploy" para comenzar!
+
+Nota: debido a esto [#58](https://github.com/anuraghazra/github-readme-stats/pull/58) podríamos manejar más de 5 mil peticiones sin tener ningún problema con el downtime :D
