+# DFBnc Dockerfile
+
+This is a dockerised version of [DFBnc](https://github.com/ShaneMcC/DFBnc/).
+
+## Usage
+
+Create a named volume to persist data:
+
+```bash
+docker volume create --name dfbnc-data
+```
+
+Pull the image for the desired version of DFBnc:
+
+```bash
+docker pull csmith/dfbnc:0.3
+```
+
+Start a container, exposing ports as needed:
+
+```bash
+docker run -d --name dfbnc \
+              --restart always \
+              -p 33263 \
+              -v dfbnc-data:/var/lib/dfbnc \
+              csmith/dfbnc:0.3
+```
+
+The container exposes these ports:
+
+  * 33262 (unencrypted IRC connection)
+  * 33263 (encrypted IRC connection) 
+
+To enable encrypted connections you will need to follow the instructions
+on the [DFBnc wiki](https://github.com/ShaneMcC/DFBnc/wiki/SSL-Listen-Hosts).
