 ## Usage
+
 1. Launch os_compat_ISLAND machine and upload your binaries/update island. Reset island environment.
 2. Launch/Reboot all other os_compat test machines (Can be filtered with tag "Puropose: os_compat_instance")
 3. Wait until machines boot and run monkey
 4. Launch `test_compatibility.py` pytest script with island ip parameter 
 (e.g. `test_compatibility.py --island 111.111.111.111:5000`)
+
+## Machines
+
+Since island machine is built from custom AMI it already has the following credentials:
+
+Administrator: %tPHGz8ZuQsBnEUgdpz!6f&elGnFy?;.
+
+The following machines does not download monkey automatically, so you'll have to manually check them:
+
+- os_compat_kali_2019
+- os_compat_oracle_6
+- os_compat_oracle_7
+- windows_2003_r2_32
+- windows_2003
+
+A quick reference for usernames on different machines (if in doubt check official docs):
+- Ubuntu: ubuntu
+- Oracle: clckwrk
+- CentOS: centos
+- Everything else: ec2-user
