 # idleterm
-Idle terminal screen made for fun (c++)
+
+I made idleterm to have something similar to [unimatrix](https://github.com/will8211/unimatrix) but made in C++ and a lot simpler, because I wanted an idle terminal screen running on very low-end devices. It currently is only tested on Linux, so feel free to make a windows version and talk to me if you want it to be on the main repo.
+## Dependencies
+
+The libx11-dev headers and libxrandr-dev packages, as well as g++ and libg++ to compile the code.
+
+Ubuntu:
+```bash
+sudo apt install libx11-dev libxrandr-dev g++ libg++
+```
+Arch: if you use X11 and have Xrandr installed, the libs should be there.
+```
+sudo pacman -Sy gcc xorg-server xorg-xrandr --needed
+```
+## Installation
+
+On any linux distro, just git clone the repo and run the install script (uses sudo to install it on the right folder)
+
+```bash
+  git clone https://github.com/augustopereiratx/idleterm
+  cd idleterm
+  ./install.sh
+```
+
+To run it, run `idleterm`. I recommend reading the help prompt by using the `-h` flag.
