 # CertManager
 
+### Features to Add
+ - Integrations as modules (systemd integration, generic commands, docker integration)
+ - Dedicated builds for server, client, and executor(?)
+
+## Quick Start
+
+## Daemonizing CertManager
+The `install` command creates the certman user, directories, and runs chown on the created dirs
+
+### Server
+
+```bash
+sudo certman install -mode server
+sudo certman new-domain example.com
+```
+
+### Client
+```bash
+sudo certman install -mode client
+sudo certman new-domain example.com
+```
