Major Initial Push

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

 # Synology Docker Compose Example
+
+This folder is an example `docker-compose.yml` file and a `.env` file for using docker through a Synology Server.
+
+## Directions
+First, create the directories where you want the containers to save everything. I use the same base directory for them, like: `/volume1/Docker/grafana`, then inside the `./grafana` directory: `./grafana` and `./influxdb`. Its best to use the command line over SSH to create these directories, AFTER you have the primary shared directory already created. (`Control Panel -> Shared Folder -> Create`)
+
+`sudo mkdir -p /volume[#]/[Shared Directory]/Grafana/{grafana,influxdb}`
+
+Where `/volume[#]` is the volume number,
+`[Shared Directory]` is the shared directory from above, and then
+`{grafana,influxdb}` needs to be copied as-is, curly brackets and all.
+
+You still have to [do this prep work](https://github.com/unifi-poller/unifi-poller/wiki/Synology-HOWTO#method-2) creating the `unifipoller` user, which I'll re-iterate here:
+
+#. Create a new user account on the Synology from the Control Panel:
+    - Name the user `grafana`
+    - Set the password (you don't need to logon as grafana and change it)
+    - `Disallow Password Change`
+    - Assign them to the user group `users`
+    - Give them `r/w` permission to the folder you created e.g. `/docker/grafana`
+    - Don't assign them **anything** else - the point of this user is for security's sake.
+#. SSH into your Synology
+#. Run the following command to find the PID of the user you created and set the variable `GRAFANA_LOCAL_USERID` in your `.env` file:
+    - `sudo id grafana`
+    - `GRAFANA_LOCAL_USERID=1026`
