+# Taking small steps to learn Ansible; I will write as a notes to myself.
+
+## What is Ansible ?
+Ansible is automation tool for making infrastructure as code.
+Helps with managing multiple servers/machines from one code base, making sure all the servers where the ansible is executed have the same configuration. 
+Ansible is agentless, does not need installing ansible on target machine, only python interpreter.
+### Nodes 
+- Control Node (From which is ansible executed to managed nodes) 
+- Managed Node (Server/Machine which we are managing such as remote hosts, PC-s, servers, embedded devices) 
+
+## Ansible Repo (dir)
+Consists of several parts: 
+- Inventory (Holds hosts to manage)  
+- Playbooks (What should be executed on the target host) 
+- Modules 
+- Ansible Configuration
+### Playbooks
+- Set of plays which are executed on target machine.
+- Each play has a set of tasks 
+- Multiple repetetive tasks can be group inside **ROLES** 
+- **ROLES** (Tasks, Handlers, Vars, Plugins, Templates, Files)
