 ## Coding convention
 
-Archinstall's goal is to follow [PEP8](https://www.python.org/dev/peps/pep-0008/) as best as it can with some minor exceptions.<br>
+ArchInstall's goal is to follow [PEP8](https://www.python.org/dev/peps/pep-0008/) as best as it can with some minor exceptions.<br>
+
 The exceptions to PEP8 are:
 
- * Archinstall uses [tabs instead of spaces](https://www.python.org/dev/peps/pep-0008/#tabs-or-spaces) simply to make it easier for non-IDE developers to navigate the code *(Tab display-width should be equal to 4 spaces)*. Exception to the rule are comments that need fine-tuned indentation for documentation purposes.
- * [Line length](https://www.python.org/dev/peps/pep-0008/#maximum-line-length) should aim for no more than 100 characters, but not strictly enforced.
- * [Line breaks before/after binary operator](https://www.python.org/dev/peps/pep-0008/#should-a-line-break-before-or-after-a-binary-operator) is not enforced, as long as the style of line breaks are consistent within the same code block.
- * Archinstall should always be saved with **Unix-formatted line endings** and no other platform-specific formats.
- * [Blank lines](https://www.python.org/dev/peps/pep-0008/#blank-lines) before/after imports and functions are not followed and discouraged. One space is commonly used in archinstall.
- * Multiple [Imports](https://www.python.org/dev/peps/pep-0008/#imports) on the same line is allowed, but more than five imports should be avoided on any given line. This simply saves up some space at the top of the file *(for non-IDE developers)* and will not be enforced.
- * [String quotes](https://www.python.org/dev/peps/pep-0008/#string-quotes) follow PEP8, the exception being when creating formatted strings, double-quoted strings are *preferred* but not required on the outer edges *(Example: `f"Welcome {name}"` rather than `f'Welcome {name}'`)*.

 Most of these style guidelines have been put into place after the fact *(in an attempt to clean up the code)*.<br>
 There might therefore be older code which does not follow the coding convention and the code is subject to change.

 Just another guided/automated [Arch Linux](https://wiki.archlinux.org/index.php/Arch_Linux) installer with a twist.
 The installer also doubles as a python library to install Arch Linux and manage services, packages and other things inside the installed system *(Usually from a live medium)*.

Further down are examples and cheat sheets on how to create different live ISO's.
 
 ## Unattended installation based on MAC address
 
-Archinstall comes with a [unattended](examples/unattended.py) example which will look for a matching profile for the machine it is being run on, based on any local MAC address. For instance, if the machine that [unattended](examples/unattended.py) is run on has the MAC address `52:54:00:12:34:56` it will look for a profile called [profiles/52-54-00-12-34-56.py](profiles/52-54-00-12-34-56.py). If it's found, the unattended installation will commence and source that profile as it's installation proceedure.
