+# Share
+Servicio para compartir arquivos.
+
+Recibe un arquivo.
+Devolve un link para descargalo.
+
+## Funcionamento
+
+### Subida
+Cando recibe un arquivo:
+- Xenera un UUID.
+- Crea un directorio "2primeirosdíxitos do uuid/$UUID/". 
+    Exemplo: 96/96683fb3-daf7-4192-83f2-508a07433fa3/
+- Garda o arquivo en ese directorio.
+- Mostra o link de descarga: https://host:port/f/$UUID
+
+### Baixada
+Cando recibe un link de baixada:
+- Colle o $UUID da URL.
+- Le o arquivo do directorio apropiado: "2primeirosdíxitos do uuid/$UUID/"
+- Envía a descarga.
+
+### Limpeza
+Executase un cron que borra os directorios co nome UUID-completo que teñan máis de 5 días.
