+\section{Introduction}
+When I was preparing lecture notes on structural mechanics related topics, it took me a lot of time to draw simple beam systems and distributions of internal forces, such as shear force diagram (SFD) and bending moment diagram (BMD), using basic TikZ. I thus tried to write some generalised commands that can draw key elements with simple syntax. That's how this package is created. This package is under GPL v3 license and/or later version. Please feel free to redistribute, expand or rewrite the functionality.
 \section{Options}
-Use following command to load the package.
+To load the package, please use the following command in the preamble.
 \begin{Verbatim}[frame=single,label=Syntax]
 \usepackage[key=val]{structmech}
 \end{Verbatim}
-Available options are:
+Some options are available for controlling the parameters used during plotting, they are:
 \begin{enumerate}
-\item axial: Define the axial force color. \Highlight{axial=colorValue}. Any predefined color value is acceptable.
-\item rotation: Define the rotation arc color. \Highlight{rotation=colorValue}. Any predefined color value is acceptable.
-\item node: Define the nodal force/displacement color. \Highlight{node=colorValue}. Any predefined color value is acceptable.
-\item fill: Define the fill patch color. \Highlight{fill=colorValue}. Any predefined color value is acceptable.
-\item convention: Define the sign convention. Value \Highlight{convention=sign} draws all quantities along positive direction and indicate negative quantities with minus sign $-$. Value \Highlight{convention=direction} label all numbers as positive but draw the negative quantities along negative directions.
+\item \Highlight{fill} defines the default fill patch colour, any predefined colour value is acceptable.
+\item \Highlight{line} defines the default line colour, any predefined colour value is acceptable.
+\item \Highlight{node} defines the nodal force/displacement colour, any predefined colour value is acceptable.
+\item \Highlight{axis} defines the axial force/displacement colour, any predefined colour value is acceptable.
+\item \Highlight{rotation} defines the rotation force/displacement colour, any predefined colour value is acceptable.
+\item \Highlight{convention} defines the sign convention, value \Highlight{convention=sign} draws all quantities along the positive direction and indicates the negative quantities with minus sign $-$, value \Highlight{convention=direction} labels all numbers as positive values but draws the negative quantities along the negative direction.
+\item \Highlight{showvalue} defines whether to show the values when plotting the diagrams of the internal forces, possible values are \Highlight{showvalue=on} and \Highlight{showvalue=off}.
+\item \Highlight{absvalue} defines whether to show the absolute values when plotting the diagrams of the internal forces, possible values are \Highlight{absvalue=on} and \Highlight{absvalue=off}.
+\item \Highlight{opacity} defines the fill patch opacity, default value is $0.4$.
+\item \Highlight{linewidth} defines the line width, default value is $0.4$ millimetre.
 \end{enumerate}
-Use following command to change option values.
+These options can be changed in the document via the following command.

 It should be noted that parameter \Highlight{\#6} defines the difference of the true moment value and the corresponding value of an assumed linear distribution. The positive value indicates that the parabola bends towards the local positive direction. Since this command draws a parabola, the load should be a uniformly distributed load. So this value \Highlight{\#6} is $\pm\dfrac{wl^2}{8}$, the sign depends on the direction of the UDL.
