+# How to use Kaui on DC/OS
+
+Kaui is the administrative UI for [Kill Bill](https://killbill.io/), the open-source subscription billing and payments platform.
+
+**Table of Contents**:
+
+- [Prerequisites](#prerequisites)
+- [Configure MySQL](#configure-mysql)
+- [Install Kaui](#install-kaui)
+- [Next steps](#next-steps)
+
+## Prerequisites
+
+- A running DC/OS 1.9 cluster with at least 1 node with 1 CPU and 2 GB of RAM available.
+- [DC/OS CLI](https://dcos.io/docs/1.9/usage/cli/install/) installed.
+- MySQL and Kill Bill installed.
+
+## Configure MySQL
+
+Setup the DDL (replace `a1.dcos` with the hostname returned by `dcos task mysql`):
+
+```bash
+echo "create database kaui" | mysql -h a1.dcos -u root -proot
+curl -s https://raw.githubusercontent.com/killbill/killbill-admin-ui/master/db/ddl.sql | mysql -h a1.dcos -u root -proot kaui
+echo "insert into kaui_allowed_users (kb_username, description, created_at, updated_at) values ('admin', 'super admin', NOW(), NOW());" | mysql -h a1.dcos -u root -proot kaui
+echo "create user kaui identified by 'kaui' ; grant all privileges on kaui.* to 'kaui'@'%' ; flush privileges" | mysql -h a1.dcos -u root -proot
+```
+
+## Install Kaui
+
+Create a file called `config.json` and set the following properties:
+
+```json
+{
+  "database": {
+    "host": "a1.dcos:3306",
+    "name": "kaui",
+    "user": "kaui",
+    "password": "kaui"
+  },
+  "killbill": {
+    "host": "http://marathon-lb-internal.marathon.mesos:10080"
+  }
+}
+```
+
+Then, install Kaui:
+
+```bash
+dcos package install kaui --yes --options=config.json
+```
+
+You can follow the installation process via:
+
+```bash
+dcos task log kaui --follow
+```
+
+Verify the installation was successful by visiting http://m1.dcos/service/kaui/ (replace `m1.dcos` with the hostname of your Marathon instance). Note: you need to be logged-in in Marathon.
+
+Additionally, verify the integration with Marathon-lb by going to http://a1.dcos:9090/haproxy?stats (replace `a1.dcos` with the hostname returned by `dcos task marathon-lb-internal`). You should see entries for `kaui_10090`. Running `curl http://a1.dcos:10090` a few times should update the HAProxy stats. Kaui is now available in the cluster behind `marathon-lb-internal.marathon.mesos:10090`.
+
+## Next steps
+
+Documentation and tutorials can be found at http://docs.killbill.io/.

+## Install MySQL
+
+Create a file called `config.json` and set the following properties:
+
+```json
+{
+  "service": {
+    "name": "mysql"
+  },
+  "database": {
+    "name": "killbill",

+  }
+}
+```
+
+Then, install MySQL:
+
+```bash
+dcos package install mysql --y --options=config.json
+```
+
+Finally, setup the DDL (replace `a1.dcos` with the hostname returned by `dcos task mysql`):
+
+```bash
+curl -s http://docs.killbill.io/0.18/ddl.sql | mysql -h a1.dcos -u root -proot killbill
+```
+
+## Install Marathon-LB
+
+Create a file called `config.json` and set the following properties:
+
+```json
+{
+  "marathon-lb":{
+    "name":"marathon-lb-internal",
+    "haproxy-group":"internal",
+    "bind-http-https":false,
+    "role":""

+dcos package install killbill --yes --options=config.json
+```
+
+You can follow the installation process via:
+
+```bash
+dcos task log killbill --follow
+```
+
+Verify the installation was successful by visiting http://m1.dcos/service/killbill/1.0/healthcheck?pretty=true (replace `m1.dcos` with the hostname of your Marathon instance). Note: you need to be logged-in in Marathon.
