 # Customer Self-Care Web UI
 
 ## Development
+Please follow these steps to set up a development environment for ngcp-csc-ui.
 
+### Node and npm
+
+First make sure you have Node.js and npm installed, and then install and build the app.
+
+1. Install latest Node.js v6 and npm v3. It's recommended to [install and use nvm](https://github.com/creationix/nvm) to make sure you're using the right versions
+1. Clone the ngcp-csc-ui repo locally
+1. Run npm install
+
+    ```npm install```
+
+1. Build the app for dev
+
+    ```npm run dev-build```
+
+### Vagrant
+
+To run this app you also need to have a [vagrant-ngcp](https://www.sipwise.org/doc/mr4.1.1/spce/ar01s04.html#_vagrant_box_for_virtualbox) environment up and running.
+
+1. Go to your local vagrant-ngcp folder, for example
+
+    ```cd ~/Sipwise/mr/vagrant-ngcp```
+
+1. Spin up a new vagrant box
+
+    ```./v n pro1```
+
+1. SSH into vagrant box and become root
+
+    ```
+    ./v s pro1
+    sudo -s
+    ```
+
+1. Edit config.yml
+
+    ```vim /etc/ngcp-config/config.yml```
+
+1. Enable csc by finding the the "http_csc:" section of the file, and setting "csc_js_enable:" to yes
+
+    ```csc_js_enable: yes```
+
+1. Run ngcpcfg apply
+
+    ```ngcpcfg apply 'Enable http_csc'```
+
+1. Navigate into the vagrant shared local folder (configured via custom_config file in local vagrant-ngcp/users.d/ folder) and execute dev.sh script to set up symlink between local built files and vagrant files served via nginx
+
+    ```
+    cd /usr/local/devel/ngcp-csc-ui/
+    ./dev.sh
+    ```
+
+You can now access ngcp-csc-ui in browser by using the url provided by the vagrant script.
+
+### PBX Customer
+
+You need a pbx subscriber to be able to access the pbx config specific modules in ngcp-csc-ui as a user. To create a pbx subscriber we first need to enable pbx in vagrant.
+
+1. SSH into the vagrant box and become root
+
+    ```
+    ./v s pro1
+    sudo -s
+    ```
+
+1. Edit config.yml
+
+    ```vim /etc/ngcp-config/config.yml```
+
+1. Enable csc by finding the "pbx:" section of the file, and setting "enable:" to yes
+
+    ```enable: yes```
+
+1. Run ngcpcfg apply
+
+    ```ngcpcfg apply 'Enable pbx'```
+
+1. Log in to ngcp-panel with administrator credentials
+1. Go to Settings > Customers
+1. Look for customer row with "Cloud PBX Account" written in "Product" column, and click "Details" for that row
+1. Go to Subscribers, and click "Create Subscribers". It's good to note that the first subscriber we create becomes the "pilot" for this customer
+1. In the "Domains" section, select the row with your local vagrant ip address shown in the "Domain" column
+1. For E.164 Number input a dummy number, for example 43 12 34567
+1. Input dummy "Display Name", "Email", "Web Username/Password", and "Sip Username/Password", and make sure to select  "Administrative", then press "Save"
+1. Create another subscriber. This new subscriber (and all subsequent ones) will then becomes a normal pbx subscriber
+1. For normal subscribers input an extension in addition to the other fields mentioned above (including "Administrative"), then press "Save"
+
+Now you can log in to csc with one of the normal subscriber you just created. URL for login is the same as for accessing ngcp-panel admin, except with csc suffix and no port specified:
+
+```https://<your-ip-address>/csc```
