+ZNC Docker image
+====================
+
+This container image includes ZNC-1.6.3 for OpenShift and general usage.
+
+Environment variables and volumes
+----------------------------------
+
+The following environment variable influence the ZNC configuration file (and optional)
+
+|    Variable name      |    Description                   |    Default
+| :-------------------- | -------------------------------- | -------------------------
+|  `ZNC_ADMIN_PASSWORD` | Sets password for ZNC admin User |  admin
+
+You can also set the following mount points by passing the `-v /host:/container` flag to Docker.
+
+|  Volume mount point      | Description        |
+| :----------------------- | ------------------ |
+|  `/var/lib/znc-data`     | ZNC data directory |
+
+**Notice: When mouting a directory from the host into the container, ensure that the mounted
+directory has the appropriate permissions and that the owner and group of the directory
+matches the user UID which is running inside the container.**
+
+Usage
+---------------------------------
+
+For this, we will assume that you are using the `znc` image.
+If you don't want to store the optional variable and data directory then execute the following command:
+
+```
+$ docker run -d --name znc -p 6667:6667 znc
+```
+
+This will create a container named `znc` running znc sever with `admin` as user
+and `admin` credentials. Port 6667 will be exposed and mapped
+to the host. If you want your ZNC to be persistent across container executions,
+also add a `-v /host/znc/data:/var/lib/znc-data` argument. This will be the ZNC
+data directory.
+
+
+ZNC admin user
+---------------------------------
+The admin user has `admin` password set by default.
+You can set it by setting the `ZNC_ADMIN_PASSWORD` environment variable.
