+# Adhost 
+
+Introducing Adhost2, a lightweight ad blocker that uses a simple shell script to set up the host file. With no bells and whistles, Adhost2 efficiently blocks unwanted ads on your system, providing a faster and smoother browsing experience. Whether you're tired of pop-ups, banners, or other pesky ads, Adhost2 has got you covered.
+
+Here's a README file in Markdown format based on the script you provided:
+
+## How it works 
+
+Adhost2 is a script that updates the /etc/hosts file on a Linux system with a list of hosts obtained from a file or custom input. It can be used to block or redirect hosts.
+
+## Usage
+
+Run the script with sudo privileges:
+
+```bash
+sudo ./adhost2
+```
+
+If you want to use a custom host list, specify the file path using the -h option:
+
+```bash
+sudo ./adhost2 -h /path/to/custom-host-list
+```
+
+To uninstall Adhost2 and restore the original /etc/hosts file, run:
+
+```bash
+sudo ./adhost2 uninstall
+```
+
+## Prerequisites
+
+- Linux system
+- Curl
+
+## Notes
+
+- The script must be run from the hosts directory (hint: from the unzip dir).
+- If you interrupt the script with Ctrl+C, it will restore the original /etc/hosts file.
+- The script must be run with sudo privileges.
+- The default host list is /usr/share/adhost/adhost2.
