-Terraform Provider PuppetDB
+PuppetDB Terraform Provider
 ===========================
+
+This is a Terraform provider to interact with the [PuppetDB](https://puppet.com/docs/puppetdb/latest/index.html). It allows to verify that a node was properly registered in a PuppetDB and to clean it upon decommissing the node.
+
+
+Requirements
+------------
+
+-	[Terraform](https://www.terraform.io/downloads.html) 0.10.x
+-	[Go](https://golang.org/doc/install) 1.8 (to build the provider plugin)
+
+Building The Provider
+---------------------
+
+Clone repository to: `$GOPATH/src/github.com/camptocamp/terraform-provider-puppetdb`
+
+```sh
+$ mkdir -p $GOPATH/src/github.com/camptocamp; cd $GOPATH/src/github.com/camptocamp
+$ git clone git@github.com:camptocamp/terraform-provider-puppetdb
+```
+
+Enter the provider directory and build the provider
+
+```sh
+$ cd $GOPATH/src/github.com/camptocamp/terraform-provider-puppetdb
+$ make build
+```
+
+Using the provider
+----------------------
+
+```hcl
+provider puppetdb {
+  url = "https://puppetdb:8081"
+  cert = "certs/puppetdb.crt"
+  key = "certs/puppetdb.key"
+  ca = "certs/ca.pem"
+  
+}
+
+resource puppetdb_node "foo" {
+   certname = "foo.example.com"
+}
+```
+
+
+Developing the Provider
+---------------------------
+
+If you wish to work on the provider, you'll first need [Go](http://www.golang.org) installed on your machine (version 1.8+ is *required*). You'll also need to correctly setup a [GOPATH](http://golang.org/doc/code.html#GOPATH), as well as adding `$GOPATH/bin` to your `$PATH`.
+
+To compile the provider, run `make build`. This will build the provider and put the provider binary in the `$GOPATH/bin` directory.
+
+```sh
+$ make bin
+...
+$ $GOPATH/bin/terraform-provider-puppetdb
+...
+```
+
+In order to test the provider, you can simply run `make test`.
+
+```sh
+$ make test
+```
+
+In order to run the full suite of Acceptance tests, run `make testacc`.
+
+*Note:* Acceptance tests create real resources, and often cost money to run.
+
+```sh
+$ make testacc
+```
