-A [NBD](https://en.wikipedia.org/wiki/Network_block_device) server replaced HDL server.
-NBD is [formally documented](https://github.com/NetworkBlockDevice/nbd/blob/master/doc/proto.md)
-and developed as a collaborative open standard.
-The current implementation of the server is based on [lwNBD](https://github.com/bignaux/lwNBD),
-go there to contribute.
-The main advantage of using NBD is that the client will simulate a similar
-interface to the OS as if the device was plugged directly into your machine.
-All your favorite software that worked with the device directly connected to your
-machine, will work with the device accessible through the network.
-
-Currently, only export for HDD is supported by the server.
-You can use hdl-dump, pfs-shell, or even directly edit disk in some hex editor.
-Example, how to install HDL game to the HDD:
-Connect with your choosen client, then `hdl_dump inject_dvd ps2/nbd "Test Game" ./TEST.ISO`
-and when you're done, disconnect the client.
-
-So you need a NBD client.
-Here we list some known compatible clients and how to use them.
+OPL now uses an [NBD](https://en.wikipedia.org/wiki/Network_block_device) server to share the internal hard drive, instead of HDL server.
+NBD is [formally documented](https://github.com/NetworkBlockDevice/nbd/blob/master/doc/proto.md) and developed as a collaborative open standard.
+
+The current implementation of the server is based on [lwNBD](https://github.com/bignaux/lwNBD), go there to contribute on the NBD code itself.
+
+The main advantage of using NBD is that the client will expose the drive to your operating system in a similar way as a directly attached drive.
+This means that any utility that worked with the drive when it was directly attached should work the same way with NBD.
+
+OPL currently only supports exporting (sharing out) the PS2's drive.
+
+You can use `hdl-dump`, `pfs-shell`, or even directly edit the disk in a hex editor.
+
+For example, to use `hdl_dump` to install a game to the HDD:
+
+  * Connect with your choosen client (OS specific)
+  * Run `hdl_dump inject_dvd ps2/nbd "Test Game" ./TEST.ISO`
+  * Disconnect the client.
+
+To use the NBD server in OPL:
+
+  * Grab the latest beta version (OPL 1.1.0 (current stable) has some bugs in the NBD server) - go to the [Releases](https://github.com/ps2homebrew/Open-PS2-Loader/releases) section and grab the one at the top.
+  * Ensure OPL is configured with an IP address (either static or DHCP).
+  * Open the menu and select "Start NBD server". Once it's ready, it should update the screen to say "NBD Server running..."
+  * Now you can connect with any of the following NBD clients.
