Variables:
- Removed the `...Rendering_callback_url` references
- Removed the `GRAFANA_NETWORK` variables, as the network name can't be a variable.
Instructions:
- Fixed a few errors
- Added the section for running `docker-compose up -d` to start the containers, and then included creating the influx database instructions utilizing the GUI.
This is the first push with most of the edits/variables in place. Most of whats left is filling out the `README.md` file for the variables and what they mean and/or need.
- Moved most of the editable/user configurable options to variables inside of the `docker-compose.example.env` file
- Wrote the explainer for the directory creation and the user creation that is necessary
