+Starting EC2 machine
+--------------------
+
+1. init git submodules
+
+    git submodule update --init --recursive
+
+2. setup AWS vars like this (change fields appropriately):
+
+    cat > group_vars/all.yaml <<EOF
+    ---
+    aws:
+      image: ami-004f552bba0e5f64f
+      profile: fedora-copr  # you need credentials for this
+      ssh_key: praiskup
+      instance_type: t2.xlarge
+      security_group: mock-testing
+      root_volume_size: 60
+      infra_subnet: subnet-09c74a3e6420a206b
+    EOF
+
+3. setup credentials/aws config:
+
+    cat ~/.aws/config
+    [profile fedora-copr]
+    region = us-east-1
+    output = table
+    $ cast ~/.aws/
+
+    cat ~/.aws/credentials
+    [fedora-copr]
+    aws_access_key_id=<the-key-id>
+    aws_secret_access_key=<the-secret-key>
+
+4. start the machine
