My second program, an installer.
To make it your own, just change a few strings toward the top:
Spoiler

-- OS Config
os_name = "CWCOS"
os_version_major = 0
os_version_minor = 1
os_version_revision = 0
os_version_abr = "alpha"
license_url = "http://opensource.org/licenses/BSD-3-Clause"
github_repo = "CodingWithClass/CWCOS"
os_name: Name of the app
Version:

os_version_major.."."..os_version_minor.."."..os_version_revision.." "..os_version_abr
os_version_abr: alpha, beta, release, etc
license_url: URL of the license
github_repo: GitHub repo storing the URL list, will be explained later

URL LIST
Spoiler1. Create a GitHub repo and add a file called 
install_files.textutils
.
2. Store a table in the following format serialized with textutils in that file
Format:
SpoilerKey: File name in filesystem (no preceeding slash)
Value: URL to download file from
3. Profit!

No pics, no clicks:

To install the installer as startup (why?), 
pastebin run csC29fp8
