+CLI Single Sign On
+===================================
+
+This java-based utility is meant for providing Keycloak integration to 
+command line applications that are either written in Java or another language.  The
+idea is that the Java app provided by this utility performs a login for a specific
+client, parses responses, and exports an access token as an environment variable
+that can be used by the command line utility you are accessing.
+
+So, the idea is that you create a login script as follows:
+
+    #!/bin/sh
+    export KC_TOKEN_RESPONSE=`java -DKEYCLOAK_TOKEN_RESPONSE=$KC_TOKEN_RESPONSE -DKEYCLOAK_AUTH_SERVER=$KC_AUTH_SERVER -DKEYCLOAK_REALM=$KC_REALM -DKEYCLOAK_CLIENT=$KC_CLIENT -jar target/keycloak-cli-sso-3.3.0.CR1-SNAPSHOT.jar login`
+    export KC_ACCESS_TOKEN=`java -DKEYCLOAK_TOKEN_RESPONSE=$KC_TOKEN_RESPONSE -jar target/keycloak-cli-sso-3.3.0.CR1-SNAPSHOT.jar token`
+    
+
+You pass in the parameters for connecting to Keycloak through Java system properties.  The command `login` will perform the following steps:
+1. Look to see if `KEYCLOAK_TOKEN_RESPONSE` is set.  If so, it will check expiration information and perform a refresh token call if the token needs refreshing.
+2. If `KEYCLOAK_TOKEN_RESPONSE` is not set, then it will use open a browser and perform a login to obtain an OAuth token response back.
+3. The output to STDOUT will be the oauth accesss token response.  This will be stored by the script in an environment variable.
+4. The 2nd line of the script extracts the access token from the response json and stuffs it in an environment variable that will be used by the CLI application.
+
+So, the idea is that you wrap your CLI application within this script and extract the access token
+from an environment variable.  For example, if our CLI application is a C program named `mycli` the script would look like this:
+
+    #!/bin/sh
+    export KC_TOKEN_RESPONSE=`java -DKEYCLOAK_TOKEN_RESPONSE=$KC_TOKEN_RESPONSE -DKEYCLOAK_AUTH_SERVER=$KC_AUTH_SERVER -DKEYCLOAK_REALM=$KC_REALM -DKEYCLOAK_CLIENT=$KC_CLIENT -jar target/keycloak-cli-sso-3.3.0.CR1-SNAPSHOT.jar login`
+    export KC_ACCESS_TOKEN=`java -DKEYCLOAK_TOKEN_RESPONSE=$KC_TOKEN_RESPONSE -jar target/keycloak-cli-sso-3.3.0.CR1-SNAPSHOT.jar token`
+    mycli $@
+    
+You would invoke it as follows:
+    
+    $ . mycli.sh
+
+Using the `.` so that the environment variables get exported.
