+## Linux / Mac using make and xelatex
+1. `make`

+1. The following steps apply only if you want the documentation (recommended).
+  1. Run `latex` on `physconst.dtx` to create the `.pdf` file. e.g. `xelatex physconst.pdf`.

+  1. Run `makeindex` to create the change log, e.g. `makeindex -s gglo.ist -o physconst.gls physconst.glo`.
+  1. Run `latex` on `physconst.dtx` to create the `.pdf` file with index and change log. e.g. `xelatex physconst.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).
 
 # Installation
-For linux, run `make` to generate the package (.sty file) and documentation.
-If you are using texlive (most modern linux distributions use texlive), you may 
-then run `sudo make localinstall` to install the package to your latex 
-distribution. If you are not using texlive, you will need to manually
-copy the .sty file into either the folder where your .tex files reside that
-require the package, or manually install the package in your latex distribution.
+First build the project as described above.
+
+## For a single project
+1. Copy the `physconst.sty` into your project where your `.tex` files are located.
+
+## for all users and projects
+### Linux / Mac using make and xelatex
+1. `make localinstall`
+
+### 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. Create a directory named `physconst` in that location.
+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 `physconst` 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.
 
-For mac, the instructions above for linux might work. Otherwise you're sort of 
-on your own. Most likely your latex disrubution is somewhere in /usr/share.
-You will need to figure out the name and where the package files are stored, 
-then run `texhash` so that latex knows that they are there.
 
-For windows, you're kind of on your own. Instructions that might help can be
-found at [this post on StackExchange](https://tex.stackexchange.com/questions/369921/loading-packages-with-ins-and-dtx-files).
+# Uninstallation
 
+### Linux / Mac using make
+1. `make localuninstall`
+### Otherwise
+1. Figure out where your LaTeX local packages are installed.
+1. Delete the directory named `physconst` in that location.
+1. Figure out where your LaTeX local package documentation is installed.
+1. Delete the directory named `physconst` in that location.
+1. Run `texhash` or the equivalent to let LaTeX know the package is gone.

+%
+% \section{Introduction}
+%
+%
+% This package consists of several macros that are shorthand for a variety of
+% physical constants, e.g. the speed of light.
+% The package developed out of physics and astronomy classes that I have
+% taught and wanted to ensure that I had correct values for each constant
+% and did not wish to retype them every time I use them.
+% The constants can be used in two forms, the most accurate available values,
+% or versions that are rounded to 3 significant digits for use in typical
+% classroom settings, homework assignments, etc.
+%
+% Most constants are taken from CODATA 2018, with the exception of the
+% astronomical objects, whose values are taken from their current wikipedia
+% entries. If you have an interest and/or need for more reliable data, 
+% please contact me.
+%
+%\subsection{Options}
+%
+% There are three options available: |shortconst|, |cgs|, and 
+% |unseparatedecimals|.
+% They can be invoked when the package is declared, e.g.\\ 
+% |\usepackage[shortconst]{physconst}|.
+%
+% |shortconst| will reduce the precision to 3 digits for all constants. This
+% is intended when you don't want to have the details of the constants, just
+% the general value (e.g. $1.60\times10^{-19}\Coulomb$ instead of 
+% $1.602\,176\,634\times10^{-19}\Coulomb$).
+%
+% |cgs| will provide all constants in cgs, i.e. the units used in astronomy.
+%
+% |unseparatedecimals| is for situations when you don't want spaces in the
+% decimal portion of full precision constants. E.g. the elementary charge 
+% would appear as $1.602176634\times10^{-19}\Coulomb$ instead of
+% $1.602\,176\,634\times10^{-19}\Coulomb$. (notice the gaps between digits
+% in the latter.
+%
+%\subsection{Macros}
+%
+%
+%\subsection{Normal Macros}
+%
+% The normal macros are the ones that you will typically use, whose values are
+% determined by the choice of options when the package is invoked.
+%
+% \subsection{Naming Convention}
+%
+% Each macro starts with a lower case `k' to indicate that it is a constant.
+% If the macro is of special units, e.g. eV, those units will be specified next.
+% If the macro is part of a fundamental unit group, it then gets the name of the
+% group, e.g. Mass, Charge, etc.
+% Finally is the details or name of the constants, e.g. Proton, Planck, etc.

+%\subsection{Detailed Macros}
+%
+% These macros are used to access the constants with specific units and 
+% precision. They require use of \textbackslash makeatletter and
+% \textbackslash makeatother in order to be used. They are used internally
+% by physconst to define the macros that are normally used (those described
+% above.
+%
+% \subsection{NamingConvention}
+% The detailed macros are named like \k@units@precision@name. The units
+% specify which units the constant is in (SI, cgs, or eV). For constants that
+% are independent of the unit system (e.g. Avogadro's number and the fine
+% structure constant), the units are omitted. The precision is either `short'
+% or `full' to indicate how much precision is included in the number. All short
+% precision constants have 3 significant figures. The precision of full
+% precision constants vary by their definition and/or inputs. Finally, the
+% name or description of the constant appears.
