 # churn
+
+## Installation
+
+To install churn, you need first of all a server and agents.
+
+Servers can be run via. docker.
+
+```shell
+docker run docker.io/kjuulh/churn-v2:latest  
+```
+
+To install an agent run the following script
+
+```shell
+curl https://git.front.kjuulh.io/kjuulh/churn-v2/raw/branch/main/install.sh | bash  
+```
+
+configure `~/.local/share/io.kjuulh.churn-agent/churn-agent.toml` use an editor of choice. Churn agent will generate a randomish name for the specific agent, consider giving it something more semantically meaningful to you
+
+## CLI (TBD)
+
+Using the churn cli allows sending specific commands to a set of agents
+
+```
+  
+```
