(GH-75) Created docs site scripts

`docs.sh` and `docs.ps1` scripts created to locally host and view
changes made to PRM documentation in the `docs/md/content` directory.

Added information pertaining to the local installation of the docs site to the `README.md`.

Added `docs/site` to .gitignore to prevent local site installation being visible to git.

+## Locally host documentation site
+
+The DevX documentation site can be locally hosted and changes made to the markdown files inside of the `docs/md/content` directory will
+be visible on the site.
+
+### Prerequisites
+
+Essential software that will need to be installed to run the documentation site locally:
+
+- Git version control
+- Hugo extended version
+- Nodejs and NPM
+
+### Install site

+
+```bash
+./docs.sh
+```
+
+This will install and run the documentation site. The site can be found at `http://localhost:1313/devx`. All updates will to the
+`docs/md/content` directory will hot reload the site.
+
+To stop the running `ctrl + c` in the terminal window in which it is running.
+
+### Run site
