 Download the latest release [here](https://github.com/elituf/gta-tools/releases/latest/download/gta-tools.exe) and place it somewhere convenient for you, such as Documents. You could then make a shortcut titled "GTA Tools", and pin it to taskbar or Start.
 
 **Option 2** — <ins>Build from source</ins>  
-You will need the Rust toolchain, which can be obtained [here](https://rustup.rs). Follow the instructions of its installer. Once you have Rust installed, clone this repo and navigate to it. At this point, you should probably `git checkout x.x.x`, where `x.x.x` is the latest tag. You can then run `cargo build --release`.

 ## Guide
 
-Every feature of GTA Tools is Legacy/Enhanced-agnostic. Some functionality of GTA Tools requires administrator access. If necessary, GTA Tools can either be started as admin manually, or, the user can simply use the <kbd>Elevate</kbd> button to relaunch GTA Tools as admin.

This feature requires administrator, and blocks/unblocks GTA V's entire internet access using the Windows Firewall. The coloured indicator dot has these meanings:

-## Issues
+This feature can also be changed to <kbd>Rockstar save server access</kbd> via the **Network** dropdown of the settings. When in this mode, instead of blocking the entire game's network, it will only block the Rockstar save server at the IP `192.81.241.171`. The IP can also be changed in the same settings, if ever needed.
 
-- I have noticed that on my current Windows 10 install, when not elevated (administrator), the <kbd>Force close game</kbd> and <kbd>Empty current session</kbd> features can fail due to being denied access. This was tested by other people and is not guaranteed to happen. If this does happen to you, I recommend using GTA Tools always in elevated mode. Check "Always start elevated" in the Settings tab.
