 ==========
 
-Skeleton project for
-[Nomad task driver plugins](https://www.nomadproject.io/docs/drivers/index.html).
-
-This project is intended for bootstrapping development of a new task driver
-plugin.

+A Nomad driver to run Nix jobs.
+Uses the same isolation mechanism as the `exec` driver.
+Partially based on [`nomad-driver-nix`](https://github.com/input-output-hk/nomad-driver-nix)
 
 Requirements

 - [Go](https://golang.org/doc/install) v1.18 or later (to compile the plugin)
 - [Nomad](https://www.nomadproject.io/downloads.html) v0.9+ (to run the plugin)
 
-Building the Skeleton Plugin
+Building and using the Nix driver plugin
 -------------------
 
-[Generate](https://github.com/hashicorp/nomad-skeleton-driver-plugin/generate)
-a new repository in your account from this template by clicking the `Use this
-template` button above.
-
-Clone the repository somewhere in your computer. This project uses
-[Go modules](https://blog.golang.org/using-go-modules) so you will need to set
-the environment variable `GO111MODULE=on` or work outside your `GOPATH` if it
-is set to `auto` or not declared.
-
-```sh
-$ git clone git@github.com:<ORG>/<REPO>git
-```
-
-Enter the plugin directory and update the paths in `go.mod` and `main.go` to
-match your repository path.
-
-```diff
-// go.mod
-
-- module github.com/hashicorp/nomad-skeleton-driver-plugin
-+ module github.com/<ORG>/<REPO>
-...
-```
-
-```diff
-// main.go
-
-package main
-
-import (
-    log "github.com/hashicorp/go-hclog"
--   "github.com/hashicorp/nomad-skeleton-driver-plugin/hello"
-+.  "github.com/<REPO>/<ORG>/hello"
-...
-
-```
-
-Build the skeleton plugin.
-
-```sh
-$ make build
-```
-
-## Deploying Driver Plugins in Nomad
-
-The initial version of the skeleton is a simple task that outputs a greeting.
-You can try it out by starting a Nomad agent and running the job provided in
-the `example` folder:
+To build the plugin and run a dev agent:
 
 ```sh
 $ make build
 $ nomad agent -dev -config=./example/agent.hcl -plugin-dir=$(pwd)
 
 # in another shell
-$ nomad run ./example/example.nomad
+$ nomad run ./example/example-batch.hcl
+$ nomad run ./example/example-service.hcl
 $ nomad logs <ALLOCATION ID>
 ```
