-# Midas
+# midas
+A topology aware zero touch provisioning (ZTP) tool for network devices.
 
+## Supported operating systems:
+  - Juniper Junos
+  - Cisco IOS
+
+## Modules
+### midasd
+The socket DHCP portion of midas.
+
+### midast
+The networkx topology portion of midas.
+
+### midasp
+The YAML/Jinja provisioning portion of midas.
+
+## Installation / usage
+```
+  $ cd midas
+  $ chmod +x midas
+  $ sudo ./midas
+```
+
+## Tips
+  - When building your topology.yaml the visualisation builds top to bottom, arrange your nodes and edges in such a way that they correspond to the correct side of the graph, for neatness.
+
+## Dependencies
+  - networkx
+  - pygraphviz
+  - yaml
+  - jinja2

+# Todo
+# 1. Implement giaddr inspection as backup to packet source address, current using socket source IP instead
+    # Not needed? Adds further complexity and lines of code, socket already reports source IP address
+# 2. Add fingerprints / persistent lease storage system (ensure that duplicate packets are only printed once, i.e. Cisco sends multiple release packets)
+# 3. Work out what variables can be made more dynamic, i.e. reply packet options - build from a YAML file?
+# 4. Make IP allocation & config var (YAML) generation automatic
+# 5. Implement socket.inet_aton() function
+# 6. PCAP from PC to capture DHCP option values that are not yet printed in a human readable format
+# 7. Mount lab Pi as NFS share on valykrie Pi to create automatic backups with duplicati
