+# Start Using Kubernetes (k3s) with Vagrant
+
+Aquest repositori mostra com desplegar un clúster lleuger de Kubernetes (k3s) usant Vagrant per a desenvolupament i proves ràpides.
+
+**Prerequisits**
+
+- Vagrant instal·lat
+- Un provider de VM (VirtualBox, Parallels, o un provider suportat)
+- `curl` i `ssh` disponibles
+
+Consulteu el `Vagrantfile` per a configuracions específiques del provider.
+
+**Ràpid Inici**
+
+1. Arrancar les màquines amb Vagrant:
+
+```bash
+vagrant up
+```
+
+2. Comprovar l'estat del clúster (ssh a una màquina i utilitzar `kubectl` integrat):
+
+```bash
+vagrant ssh -c "sudo kubectl get nodes"
+```
+
+3. Parar i eliminar les màquines:
+
+```bash
+vagrant halt
+vagrant destroy -f
+```
+
+**Detalls d'instal·lació**
+
+Les instruccions d'instal·lació i els scripts utilitzats per configurar k3s estan a [install_k3s.txt](install_k3s.txt). Revisa aquest fitxer per entendre com s'instal·la i s'inicia k3s dins de les VM.
+
+**Personalitzar**
+
+Modifica el [Vagrantfile](Vagrantfile) per canviar la mida de la VM, la xarxa o el nombre de nodes.
+
+**Contribucions i errors**
+
+Obre un issue o envia un PR amb millores o problemes trobats.
