+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

++------+
+
+	- 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 fetches packages from https://github.com/everest-linux/glacier-pkgs
-
-Install Glacier by pasting the following command into your terminal:
-```
-rm -rf /tmp/glacier && cd /tmp && git clone https://github.com/everest-linux/glacier &&
-cd glacier/install && chmod +x INSTALL-GLACIER.sh && sudo ./INSTALL-GLACIER.sh || doas ./INSTALL-GLACIER.sh
-```
-For Glacier to work properly, you need to have both wget and tar installed.
-
-Glacier depends on wget and tar for its backends. It also requires a working C compiler for source packages to work correctly. Some packages may have their own sets of dependencies. All of these are configured by default in the Everest rootfs tarball, but you may need some extra configuration to get these programs on other distros, most notably, Arch and its derivatives.
-
-Glacier is intended to be a universal package manager, and should work on all distros, providing you have wget and tar installed. For the sake of compatibility, all scripts submitted should contain **NON DISTRO SPECIFIC COMMANDS**.
-
-# Submitting Packages
-
-Packages should be submitted by sending a pull request to https://github.com/everest-linux/glacier-pkgs, with your package in the proper testing repository (if its system software, world-testing, if its gpl software, galaxy-testing, etc). A maintainer will test the package to make sure it downloads correctly.
-  
-# Latest News
-
-5/17/22 > Considering adding command line parsing
-
-5/3/22 > Multi repository support is back! 1.2
-
-5/3/22 > Multi-repository support might return, as I've discovered "||". 1.1 (only minor changes, such as line printing)
-
-4/20/22 > Colored output, and proper unicode symbols. First stable Glacier release, 1.0
-
-4/13/22 > Multi-repository support has been temporarily removed, due to incorrect error handling. 0.7.5rc
-
-4/12/22 > Added support for multiple repositories (world, galaxy, universe, multiverse, and their testing counterparts).
- 
- 4/5/22 > Added package timestamps. New package uploads will be halted until all current packages have timestamp capabilities added. To do this, add a script called (package_name).ts.sh, which should contain 2 commands:
- ```
- touch /var/log/glacier/(package_name).timestamp
- date >> /var/log/glacier/(package_name).timestamp
- ```
- 0.6rc.
- 
- 3/28/22 (again) > Added package caching. This is useful if the user wishes to customize package instruction scripts before installing. 0.5rc
- 
- 3/28/22 > Recovered from sickness, released 0.4rc. This update provides proper cleanup after an operation is complete. This is done by making a temporary directory that the tarball will be unpacked into. Also added the logo to README.md
- 
- 3/22/22 > Sorry for a lack of updates recently, I've been sick 
- 
- 3/16/22 > Vim has been added to Glacier's package collection as a source package. Additionally, a couple of bugs have been ironed out. To install vim, you must be on the latest version of Glacier. This can be done by cloning this repository, marking UPDATE-GLACIER.sh as executable, and running it as root. I plan on porting more vital system software to the repositories before I release another Everest tarball. Current version: (0.3rc)
- 
- 3/10/22 > Proper error handling has finally been added! If an operation fails, the package manager will quit, instead of continuing with the operation. Current version: (0.2rc)
-
-# Roadmap
-
-Future: musl libc and musl compiler compatability (change gcc to $CC)
-
-Sometime within the next few months: command line parsing and multi-repository support, all neccessary packages ported
