+If you have `just` installed, replace the **domain** and "**1.2.3.4**" with you own and run:
+```sh
+just matrix.yourdomain.com 1.2.3.4

+
+If you have `make`, run:
+```sh
+make domain=matrix.yourdomain.com ip=1.2.3.4

+Otherwise you may copy the files manually:
 
 1. Create a directory to hold your configuration: `mkdir -p inventory/host_vars/matrix.example.com` where `example.com` is your "base domain"
 2. Copy the sample configuration file: `cp examples/vars.yml inventory/host_vars/matrix.example.com/vars.yml`
