Oh wow.. you're just about nearly there. You will upload content via FTP. WebFTP will be easiest for you. Just go to "Manage Domains" in the left menu, and then look for your domain in the list. You should see it listed there... if not, hit Add Domain/Subdomain, and type the name in (just the taxserviceyearound.com part). Obviously it's there if you've already installed concrete5. You have all checkmarks except for two small things.
In the same place, next to your domain, hit "Web FTP" and a "net2ftp" window should show up and let you login. You will see your files in there once it connects.
Next, you need to go into these folders -- concrete/libraries/3rdparty and in that last folder you'll see a file called "htmldiff.py" hopefully. checkmark next to it, then hit CHMOD on the top right menu. Don't worry about all the checkboxes, just type "755" in the bottom box with the number already in it then hit tab, and it will fix the checks for you... then hit the big green arrow. That fixes the part about CHMOD 755 that file. I see now that those are option, so you don't truly have to do that, but I would.
You are 90% there at this point... that's the good news. Adding this database will be the last major step to setting it up, and it's good to learn, because most of them require you setup one.
Since it was a 1 click install... if it went ahead and already set up a database and all that, it should have given you the above info already, and so just enter that info and skip the manual making it yourself part. it should have made one on its own and said ok here's the servername, database name, username and password, or emailed it to you. But failing that, you can always set it up manually by following these instructions ->
Next they want a database... so back to the control panel, the to MySQL databases.
If you see none in there, hit Add New Hostname. Put a hostname in the only textbox... "mysql" without quotes is fine. then hit add this hostname!
Ok, from here you'll just fill out the boxes under 'create database'
1) make up a name. you can call it... taxserviceyearound_concrete5 for the "name"... then use hostname should be populated with like... mysql.taxserviceyearound.com
2) in the user/username dropdown, i would select "create a new user" -- this will be your concrete5 user login (it will use this account, not you, but remember it)
then from here it's simple... pull up your site, fill in your info...
name of your site would be like Tax Services Yearound, then put your email. YOu can leave add sample stuff checked. after you enter all this info and hit "install concrete" either
a) it will successfully install concrete or
b) it'll fail with some error message. if you get an error, come back and post it and we'll fix it.
server - mysql.taxserviceyearound.com
username - whatever you made
password - whatever you set it to
database name - in my example, i named it "taxserviceyearound_concrete5"
Then we can proceed....
