 # fetchit
-Works on my machine
+
+fetchit is a terminal-based system information viewer written in C++. It works like neofetch/fastfetch and consists of a single file (`main.cpp`).
+
+## Features
+
+- Displays distro, kernel, uptime, shell, CPU, GPU, RAM, and OS date information.
+- Detects distro name via `/etc/os-release`.
+- Shows ASCII logos for supported distros.
+- Reads `/usr/share/hwdata/pci.ids` for GPU names; prints hex IDs if missing.
+- Accounts for Unicode character width (for icon alignment).
+
+## Supported Distro Logos
+
+`arch`, `cachyos`, `debian`, `ubuntu`, `fedora`, `manjaro`, `opensuse`, `pop`, `linuxmint`, `endeavouros`, `void`, `alpine`
+
+## Requirements
+
+- Linux
+- A C++17-capable compiler (e.g., g++)
+- A UTF-8 terminal with ANSI color support (for icons and colors)
+- The following files/paths are read:
+  - `/etc/os-release`
+  - `/etc/hostname`
+  - `/proc/uptime`
+  - `/proc/cpuinfo`
+  - `/proc/meminfo`
+  - `/sys/bus/pci/devices/`
+  - `/sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq`
+  - `/usr/share/hwdata/pci.ids` (optional)
+
+## Build
+
+```bash
+g++ -std=c++17 -O2 -o fetchit main.cpp
+```
+
+## Run
+
+```bash
+./fetchit
+```
+
+## Sample Output
+
+```text
+                              --- murat@baklava ---
+
+       /\           distro:     Arch Linux

+                    OS Date:    6 months 17 days 3 hours 40 minutes
+```
+
+## Notes
+
+- `OS Date` is based on the creation time of `/etc/hostname`.
+- If no ASCII logo is found, only the info list is printed.
+- The distro logo is displayed in color via ANSI escape codes.
+- This tool targets Linux systems and is not expected to work on non-Linux OSes.
