+    $ ec2-add-keypair my-keypair > ~/.ec2/my-keypair.pem
+    $ chmod 600 ec2-keypair.pem
+
+### Start an instance
+
+    # Show images (AMI's) owned by amazon, or me
+    $ ec2-describe-images -o self -o amazon
+
+    # Start an instance using a given AMI image
+    $ ec2-run-instances ami-xxxxxx -k ec2-keypair
+
+    # Open up ports (in the 'default' security group)
+    $ ec2-authorize default -p 22
+    $ ec2-authorize default -p 80
+
+    # Now SSH to it
+    $ ssh -i ~/.ec2/my-keypair.pem root@ec2-xxx.amazonaws.com
+
+### Management
+
+    # Show running
+    $ ec2-describe-instances
