-This provider uses [Go modules](https://github.com/golang/go/wiki/Modules).
-Please see the Go documentation for the most up to date information about using Go modules.
+Please run `make` to see other targets available, including formatting, linting and static analysis.
 
-To add a new dependency `github.com/author/dependency` to your Terraform provider:

-go get github.com/author/dependency
-go mod tidy

-Then commit the changes to `go.mod` and `go.sum`.
 
 ## Using the Provider
 
 Please, refer to the [Terraform docs for the Juju provider](https://registry.terraform.io/providers/juju/juju/latest/docs).
 
 ## Developing the Provider
 
-If you wish to work on the provider, you'll first need [Go](http://www.golang.org) installed on your machine (see [Requirements](#requirements) above).
+### Planning & Design
 
-To compile the provider, run `go install`. This will build the provider and put the provider binary in the `$GOPATH/bin` directory.
+When creating a new resource, datasource or changing a current schema please document the 
+changes and create an github issue for review and approval before coding.
 
-To generate or update documentation, run `go generate`.
+Consider writing documents for the project-docs/decisions folder.
 
-In order to run the full suite of Acceptance tests, run `make testacc`.
+New resources and datasources will require import and use example documents.
 
-_Note:_ Acceptance tests create real resources.

-#### Linting
+### Adding Dependencies
 
-This repository uses [golangci-lint](https://golangci-lint.run/) as a linting tool as it can run multiple linters. The configuration for this tool is all handled in the file `.golangci.yaml` in the root of the repository allowing all runs of the tool to run with the same settings.
