+# Building the Package
+## Linux / Mac using make and xelatex
+1. `make`
+
+## Otherwise
+1. Run `latex` on `physunits.ins` to create the `.sty` file. e.g. `latex physunits.ins`.
+1. The following steps apply only if you want the documentation (recommended).
+  1. Run `latex` on `physunits.dtx` to create the `.pdf` file. e.g. `xelatex physunits.pdf`.
+  1. Run `makeindex` to create the index, e.g. `makeindex -s gind.ist -o physunits.ind physunits.idx`.
+  1. Run `makeindex` to create the change log, e.g. `makeindex -s gglo.ist -o physunits.gls physunits.glo`.
+  1. Run `latex` on `physunits.dtx` to create the `.pdf` file with index and change log. e.g. `xelatex physunits.pdf`.
+  1. Run `latex` on `physunits.dtx` to get the labels sorted out. e.g. `xelatex physunits.pdf`.
+
+Instructions that might help can be for windows can be found at [this post on StackExchange](https://tex.stackexchange.com/questions/369921/loading-packages-with-ins-and-dtx-files).
+

+
+### Otherwise
+Instructions that might help can be for windows can be found at [this post on StackExchange](https://tex.stackexchange.com/questions/369921/loading-packages-with-ins-and-dtx-files).
+1. Figure out where your LaTeX local packages are installed.

+1. Copy the `.sty` file into the directory you just created.
+1. Figure out where your LaTeX local package documentation is installed.
+1. Create a directory named `physunits` in that location.
+1. Copy the `.pdf` file into the directory you just created.
+1. Run `texhash` or the equivalent to let LaTeX know the package is there.
+
+
+# Uninstallation
+
+### Linux / Mac using make
+1. `make localuninstall`
+### Otherwise
+1. Figure out where your LaTeX local packages are installed.
+1. Delete the directory named `physunits` in that location.

+%
+% \section{Introduction}
+%
+%
+% This package consists of several macros that are shorthand for a variety of
+% physical units that are commonly used in introductory level physics and 
+% astronomy classes. 
+%
+% \section{Naming Convention}
+%
+% most macros consist of just the commonly used letter or unit, e.g. 
+% \textbackslash m for 
+% meters. In cases where the simple form of the unit conflicts with an existing
+% \LaTeX~macro, then the full word is used, starting with a upper-case letter,
+% e.g. \textbackslash Coulomb.
+%
+% One notable exception to the above naming convention is the use of 
+% \textbackslash gm for
+% grams, instead of \textbackslash g or \textbackslash Gram.
+%
+% \section{Base and Prefixes}
+%
+% Most units are in the base unit only, but some very commonly used prefixes
+% are available as part of the macro, e.g. \textbackslash kg for kilogram, 
+% \textbackslash cm for centimeter.
+% For base units, each macro accepts one option that can be used to specify
+% the prefix, for example \textbackslash m[n] will result in nm. The macros 
+% enforce math
+% mode, so \textbackslash m[\textbackslash micro] will result in 
+% $\mathrm{\mu m}$.
+%
+%
+% \section{Macro Usage}
