First Round Updates

Here are some of the higher-level, more basic updates that you guys mentioned so far:
- Added a small part about the `.env` file and what its for
- Changed the various references to directories from `grafana` to `unifi-poller` as the base
- Changed the user name to create in the GUI from `grafana` to `unifi-poller`. 
  - Thought this might be more streamlined(?)
  - Might want to look into changing that on the docker instructions, too, if we prefer this
  - You have to keep the `sudo id` bit later, as we can't tell the GUI to use a specific user ID.

Let me know what you think about these minor updates, here.

 This folder is an example `docker-compose.yml` file and a `.env` file for using docker through a Synology Server.
 
+The `.env` file is a special environment/variable file that `docker-compose` automatically uses to make configuration of your containers easier.

 ## 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/unifi-poller/influxdbx

 `[Shared Directory]` is the shared directory from above, and then
-`{grafana,influxdb}` needs to be copied as-is, curly brackets and all.
+create the `grafana and influxdb` directories.
 
-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)
+    - Name the user `unifi-poller`
+    - Set the password (you don't need to logon as unifipoller 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`
+    - Give them `r/w` permission to the folder you created e.g. `/docker/unifi-poller`
     - 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`
+    - `sudo id unifi-poller`
     - `GRAFANA_LOCAL_USERID=1026`
