-# Purpose
+# Overview
 
-For me to wrap head around some shit.
-Notes for troubleshooting.
+Docker is a container technology that utilizes the host OS's kernel while putting the userland applications into a sandbox.
+It is more lightweight than a full-fledged virtual machine, but you're applications need to be compatible with the host OS. 
 
-What was at one time tested and should 100% work.
+Compose is a Docker tool that allows defining containers using a YAML file and run them with a single command.
 
-# docker-compose
+The purpose of docker and docker-compose is either development or deployment.<br>
+Most of the stuff around here is about deployment, how to deploy others people work<br>
 
-`docker-compose.yml`
-```yml
-services:
-
-  whoami:
-    image: "containous/whoami"
-    container_name: "whoami"
-    hostname: "whoami"
-    ports:
-      - "80:80"
-```
+# Basics 
 
 
-
-# Scheduling and cron issues
-
-The default docker-compose deployment uses cron container.<br>
-Problem is it does not work, so Ofelia is used.<br>
-[Here](https://github.com/DoTheEvo/selfhosted-apps-docker/tree/master/ofelia)
-is guide how to set it up.
-
-Bellow is Ofelia's config file for discovery and ping check of live hosts.
-
-`config.ini`
-```ini
-[job-exec "phpipam ping"]
-schedule = @every 10m
-container = phpipam-web
-command = /usr/bin/php /phpipam/functions/scripts/pingCheck.php
-
-[job-exec "phpipam discovery"]
-schedule = @every 25m
-container = phpipam-web
-command = /usr/bin/php /phpipam/functions/scripts/discoveryCheck.php
-```
-
-# Reverse proxy
-
-Caddy v2 is used, details
-[here](https://github.com/DoTheEvo/selfhosted-apps-docker/tree/master/caddy_v2).</br>
-
-`Caddyfile`
-```
-ipam.{$MY_DOMAIN} {
-    reverse_proxy phpipam-web:80
-}
-```
-
-# First run
