 # Paperchanger
 
+## Introduction
+`Paperchanger` is a program aimed to assist one using the `xwallpaper` tool.
+
+Hence `xwallpaper` provides no comprehensive way of changing the wallpaper through a graphical selector, `paperchanger` is there to fix this flaw.
+Of course `paperchanger` offers fuctionality to change the wallpaper by passing a path to a file, just like you would with `xwallpaper`.
+
+Additionally, `paperchanger` gives you the option of specifying a default directory where all your wallpapers are stored.
+This is nice, as it provides an easier workflow for changing wallpapers.
+
+It is important to know that `paperchanger` is using the `--zoom` flag provided by `xwallpaper` internally, although this might be adjusted or extended at some point in the future.
+
+## Installation
+
+### Arch Based Systems
+
+If you are using an arch based system, you can install the `paperchanger` package from the [AUR](https://aur.archlinux.org/) (Arch User Repository).
+(Not yet available!)
+
+An AUR manager like yay may be used for an easy installation:
+
+```shell
+$ yay -S paperchanger
+```
+If you do not want to use an AUR manager, here is how to compile and install the package manually:
+
+Download the `PKGBUILD` file from this repository and move it to some folder.
+
+Navigate into this folder using:
+
+```shell
+$ cd path-to-the-folder
+```
+
+Now use the `makepkg` command to download the source files and compile the package:
+
+```shell
+$ makepkg
+```
+
+After you are done creating the package, you should have many files including a `.pkg.tar.zst` archive.
+This is your compressed ready to use `paperchanger` package, which can now be installed using pacman.
+
+```shell
+$ sudo pacman -U path-to-your-archive
+```
+
+The folder and its contents used for the installation process may now be deleted.
