+Manage packages on an Everest Linux system
+
++-----------------------+
+| [?] About Glacier [?] |
++-----------------------+
+
+Glacier's main goal is to combine the power of
+source based packaging with the simplicity of
+binary based packaging.
+
+Glacier downloads source code from
+https://git.everestlinux.org/EverestLinux/glacier-pkgs
+and compiles it locally on your system.
+
++----------------------+
+| [!] Dependencies [!] |
++----------------------+
+
+Glacier requires the following programs to function:
+
+	- sh
+	- wget/curl (any program that can download files)
+	- tar
+	- make
+	- a c compiler (tested with gcc, although others should work)
+	- python (for integrity checking)
+
++----------------------------+
+| [🠗] Installing Glacier [🠗] |
++----------------------------+
+
+Obtain the source code:
+
+	$ git clone https://git.everestlinux.org/EverestLinux/glacier
+	$ cd glacier
+
+Copy install.conf.def to install.conf
+
+	$ mv install.conf.def install.conf
+
+Make necessary adjustments to install.conf, then run
+build.sh as root.
+
+	# ./build.sh install # for first time installations
+	# ./build.sh update # for existing installations
+
++-----------------+
+| [>_] Usage [>_] |
++-----------------+
+
+	# glacier install/-f
+	# glacier update/-u
+	# glacier remove/-x
+	$ glacier query/-q
+	# glacier cache/-c
+	# glacier cache-install/-ci
+	# glacier cache-clear/-cc
+	$ glacier --debuginfo
+	$ glacier -h/--help
+	$ glacier -v/--version
+
++------+
+| News |
++------+
+
+	- 11/3/22 - Changing how packages are uninstalled
+	In Glacier's current state, it needs to download the package archive in order to remove it.
+	This is highly inefficient and presents its own risks.
+	In an upcoming update, the removal script will be retained on the system.
+	This method will be space efficient because:
+		a) Instruction scripts are mere kilobytes
+		b) For larger scripts, you will have the option of compressing them.
+	This feature is expected around 3.2.0.

-# Glacier
-Glacier is the package manager developed for Everest Linux. It automatically fetches a tarball, unzips it, and compiles it.
-
-For Glacier to work properly, it needs the following directories to be made:
-
-  `/usr/local/lib/glacier/packages`
