 Don't reimplement things that already work well. This project leans on the following libraries:
 
 * [chanced/caps](https://github.com/chanced/caps) — Handles the case manipulation.

+## More Information
+
+After the provider is installed, you can run `terraform-provider-corefunc` on the CLI.
+
+* Install with either `terraform init` or `make build`.
+* The Go binary path (discovered by running `./find-go-bin.sh`) is on your `$PATH`.
+
+This will display the following text:
+
+```bash
+terraform-provider-corefunc
+```
+
+```plain
+This binary is a plugin. These are not meant to be executed directly.
+Please execute the program that consumes these plugins, which will
+load any plugins automatically
+```
+
+However, by passing the `--help` flag, you can see the other options available, including a description of the software.
+
+```bash
+terraform-provider-corefunc --help
+```
+
+The provider has one primary sub-command: `version`. It includes long-form version information, including the build commit hash, build date, Go version, and external dependencies.
+
+```bash
+terraform-provider-corefunc version
