+# Descomplicando `Kubernetes`
+
+## Preparando o ambiente
+
+Para facilitar a instalação dos _softwares_ necessários utilizo o [`mise`][mise] como gestor de ferramentas e _runtimes_.
+
+A instalação do [`mise`][mise] pode ser feita seguindo o [guia de uso][mise-guide].
+
+Com o [`mise`][mise] instalado, executamos o seguinte comando para instalar as ferramentas:
+
+```bash
+mise install
+```
+
+E, para garantir que tudo esta correto, podemos verificar a instalação rodando:
+
+```bash
+mise current
+```
+
+O resultado esperado é:
+
+```
+kind 0.22.0
+kubectl 1.29.4
+```
+

+* [dia-01][dia-01]: subindo primeiro _cluster_ com [`kind`][kind] e fazendo _deploy_ do primeiro `pod`

+# Descomplicando `Kubernetes` - Dia 01
+
+## Criando o _cluster_ com [`kind`][kind]
+
+Para subir o _cluster_ com as [configurações especificadas][kind-config], executaremos:
+
+```bash
+kind create cluster --config ./kind-cluster.yml --name dk8s-day-001
+```
+
+## _Deploy_ do `pod` aplicando o manifesto
+
+Com o _cluster_ rodando, podemos subir um novo `pod` usando o comando:
+
+```bash
+kubectl apply -f pod.yml
+```
