+# Netbox: NetGlass
+
+View cable topology in [hopglass](https://github.com/hopglass/hopglass) fashioned graph view.
+
+## Requirements
+
+* A docker host
+* docker-compose
+
+## Prepare
+
+Netglass acts as replacement for [hoplass-server](https://github.com/hopglass/hopglass-server) and uses NetBox's API to gather wiring information.
+
+First go to your NetBox instance and create a read-only Token. Remember that tokens for users from LDAP backends do not work. Create a file `.env` with the contents
+
+```
+NETBOX_URL=https://netbox.your.tld
+NETBOX_TOKEN=70bdtoken89nhuf
+```
+
+Run `docker-compose up -d` to build the hopglass instance.
