+# Containers
+This folder contain the docker declaration for my homelab changes using portainer, when using Stack option at portainer, you can import a docker compose file from a git repository source and automatically pull changes from the git source.
+**TODO**: Explain how to setup this process
+
+## Services
+Here the list of the services that I'm running at my homelab:
+
+### wg-easy
+Link: *https://github.com/wg-easy/wg-easy/*
+
+I use wg-easy for managing the wireguard environment at my homelab, I want a VPN for some reasons:
+- Access my homelab from outside my LAN, so if I need to manage any service I can easily do without the need to expose everything for the internet.
+- Maybe If i'm in a insecure network, proxy my home internet with VPN for secure access
+- Sometimes my friend have trouble to play an online game because of routing problems from their ISPs, I can proxy my connection to them aswell.
+
+**Variables**
+There's some sensitive variables, we should configure directly in portainer these: 
+```yaml
+- PASSWORD=<insert password to access the admin painel>
+```
