+# Python bindings for libnvme
+
+We use [SWIG](http://www.swig.org/) to generate Python bindings for libnvme.
+
+## How to use
+
+```python
+#!/usr/bin/env python3
+import sys
+import pprint
+from libnvme import nvme
+
+root = nvme.root()      # This is a singleton
+root.log_level('debug') # Optional: extra debug info
+
+host = nvme.host(root)      # This "may be" a singleton. 
+sybsysnqn  = [string]       # e.g. 'nqn.2014-08.org.nvmexpress.discovery', nvme.NVME_DISC_SUBSYS_NAME, ...
+transport  = [string]       # One of: 'tcp, 'rdma', 'fc', 'loop'.
+traddr     = [IPv4 or IPv6] # e.g. '192.168.10.10', 'fd2e:853b:3cad:e135:506a:65ee:29f2:1b18', ...
+trsvcid    = [string]		# e.g. '8009', '4420', ...
+host_iface = [interface]    # e.g. 'eth1', ens256', ...
+ctrl = nvme.ctrl(subsysnqn=subsysnqn, transport=transport, traddr=traddr, trsvcid=trsvcid, host_iface=host_iface)
+
+try:
+    cfg = {
+        'hdr_digest': True,   # Enable header digests
+        'data_digest': False, # Disable data digests       
+    }
+    ctrl.connect(host, cfg)
+    print(f"connected to {ctrl.name} subsys {ctrl.subsystem.name}")
+except Exception as e:
+    sys.exit(f'Failed to connect: {e}')
+
+try:
+    log_pages = ctrl.discover()
+    print(pprint.pformat(log_pages))
+except Exception as e:
+    sys.exit(f'Failed to retrieve log pages: {e}')
+
+try:
+    ctrl.disconnect()
+except Exception as e:
+    sys.exit(f'Failed to disconnect: {e}')
