Installation

Create the directory /switch/tinfoil/ on your switch's SD card.
Copy tinfoil.nro to /switch/tinfoil/tinfoil.nro.
Obtain or generate a keys.txt file and place it in /switch/tinfoil/keys.txt. keys.txt is a text file containing various Switch encryption keys. If you plan to generate it yourself, you can find instructions here:https://gbatemp.net/threads/how-to-get-switch-keys-for-hactool-xci-decrypting.506978/ or use kezplez-nx
Supported Protocols
SD CARD
Supports installing from the local SD card. Use the URI sdmc:/ to point to the SD card. Subdirectories also work, for example sdmc://nsps/.

FTP
Regular FTP, not FTPS, not SFTP, normal plain jane [ Register or Signin to view external links. ] .

HTTP
HTTP requires directory listing / browsing be enabled.

SX USB Mass Storage Device / Hard Drive
Requires SX OS 2.2.1+. Attach the hard drive before you launch Tinfoil. Tinfoil will automatically scan the root directory, any subdirectories must be added to locations.conf. Does not currently support hot swap.

USB
Requires a configured nut server. See here for details.

NUT SERVER
Requires a configured nut server. See here for details. Always ensure you are running the latest NUT server with Tinfoil.

Trouble shooting
I see my network locations, however no files are listed
Either Tinfoil cannot cannot connect with the network settings provided, you are using http and did not enable directory browsing, your firewall is blocking the connection.

Ensure that you can connect to the FTP/HTTP/NUT server using the provided settings from a different PC than the one running the server.
Tinfoil does not support sub directories, so each directory must point to the exact directory the NSP's are located in.
Ensure your firewall is allowing external connections. Configure or disable your firewall.
If using HTTP, ensure that directory listing / browsing is enabled. This must be manually enabled with IIS.
I can see the files, but cannot download them.

If using HTTP, verify that you can download the file using a web browser. IIS requires you to add a MIME type for NSP (application/octet-stream) before you can download.
Tinfoil Hangs at startup I launch it
Tinfoil blocks on USB wait if you have your switch connected to a PC upon boot, that is not running a USB Nut server.

Disclaimer
Use at your own risk, and always have a NAND backup.

Additional Info
FAQ
What does each icon on the left mean?
On the left, you will see icons that indicate what is not yet installed on your Switch, but is on your PC (the game controller), and everything that is on your PC/server (PC icon). Anything that is listed under Games, DLC, and Updates, with the game controller icon next to it, is what is currently on your PC but not on your Switch. You can go to the Home tab to see everything that you have installed on your Switch.
