# Sovran-Scripts
# Sovran Scripts
------------------
Install scripts for self-hosting things.
## How to use these scripts
----------------------------
These should work on most newer Debian based distros that use apt.
If your using a GUI then you can download the codes zip file > unzip and open the folder >
Right click on the folder select "Open in terminal" > then type `ls` this will show whats in the folder >
then `sudo ./full_script_name.sh`. You'll need to provide an admin password.
If you are running 'headless' and dont have Git installed yet you can run :
`wget https://github.com/Enkimin/Sovran-Scripts/archive/main.tar.gz` >
then run `tar -xzvf main.tar.gz` > and `cd main` > `ls` > `sudo ./script_name.sh`
You can use Git with `git clone https://github.com/Enkimin/Sovran-Scripts.git` >
then `cd Sovran-Scripts` > `ls` > `sudo ./script_name.sh`
## Scripts
------------
### coreinstall.sh
- This script walks the user through the process of installing TOR, I2P, and Bitcoin Core.
Scripts for self-hosting. Useful tools for spinning up and maintaining self-hosted applications.
