=====Background=====

====What is an archive====
a place where data is collected, preserved, managed, and made accessible to those with permission; although many are public.

in the context of Linux, an archive is a place to store as many folders / files as one needs into one centralized file for long-term use.
====What actions can be performed on an archive?====
an archive can be compressed to be smaller
====What is compression====
the proccess of encoding data into fewer bits than the original representation
====How does compression differ from archiving?====
archiving doesn't reduce file size, while compression does.
====Types of compression (lossy vs lossless)====
after compressing a file with a lossless technique, the original image before it was compressed should look exactly the same after it is decompressed. Lossy compression makes a file lose data everytime it is compressed and decompressed. 
=====Procedure=====

=====Repository Operations=====

====Checking current repository status====
hg status brings up a list of all things ready to be staged
====Adding untracked files to repository====
hg add <File name> stages files, to get ready to be commited.
====Committing changes====
hg commit -m "your message here." committing a change initializes it for a push and gives a description to the update  
====Pushing commits upstream to server====
hg push. pushes any commits to the remote repository.
====Pulling changes from server====
