+# Awstool
 
 Tool for launching and configuring AWS EC2 instances.
 
 ## Installation
 
-Not properly gemmed up yet. You'll need to clone and set RUBYLIB environment variable to clonepath/awstools/lib. Requires the fog gem and ruby >=1.9.3.
 ```bash
-export RUBYLIB=/home/user/repos/awstools/lib
-sudo apt-get install ruby-dev # For ubuntu/debian
-gem install fog
+gem install awstool
 ```
 
 ## Usage
 
 Copy example/awstools.yaml to ~/.awstools.yaml. Fill it out to your liking.
 ```bash
-cd awstools/bin
-./awstools hostname
+awstool floop.example.com
 ```
-This will launch and instance and create an A record with route53.

+This will launch and instance and create an A record with route53.
+You can split your settings files up and then merge them on the command line with the -o flag.
+```bash
+awstool -o ~/ubuntu-14.04.yaml,~/webserver.yaml floop.example.com
+```
+This will allow for different levels of templating. Particularly useful for setting puppet 
+options and security groups. Launch a bunch of instances off of the same configs like so.
+```bash
+awstool -o ~/ubuntu-14.04.yaml,~/webserver.yaml floop1.example.com floop2.example.com jb.example.com
+# or
+awstool -o ~/ubuntu-14.04.yaml,~/webserver.yaml floop{1..5}.example.com
+```
+When launching multiple instances the tool will choose a random subnet from the subnet-ids array unless
+the -s flag or the 'subnet-id-index' option is set. It can also balance between the subnets with
+'subnet_balance: true' in settings.
