+# How to get terraform to recognize third party provider
+
+The default installation of terraform has no way of finding custom third party providers. This document shows you how to locate providers so that `terraform init` can find them and copy them to your working terraform directory when creating a new project.
+
+## Locate the provider binaries
+
+Assuming you have followed other directions the deafult locations for these binaries (on a mac at least) are as follows:
+
+```bash
+which terraform-provider-proxmox
+~/go-workspace/bin/terraform-provider-proxmox
+which terraform-provisioner-proxmox
+~/go-workspace/bin/terraform-provisioner-proxmox 
+```
+
+## Copy provider binaries
+
+You need to copy these binaries to the ~/.terraform.d directory which will also need to have a plugins directory created:
+
+```shell
+cd ~/.terraform.d
+mkdir plugins
+cd plugins
+cp ~/go-workspace/bin/terraform-provider-proxmox .
+cp ~/go-workspace/bin/terraform-provisioner-proxmox .
+```
+Once this is done, simply create a new terraform directory and do usual terraforming (terraform init etc)
