 # PDF Math Symbols - pdfMsym
-## version 1.1.0
-
 The pdfMsym package provides mathematical symbols for PDF-dependent TeX compilers.
-pdfMsym requires the font size in order to properly scale its symbols, so the following two lines must be added to your document in order to properly load it:
-
-        \input pdfmsym
-        \pdfmsymsetscalefactor{10}
-
-assuming you want to load the package at a 10pt font, you can change the 10 to whatever suits your needs.
-If you do not add the `\pdfmsymsetscalefactor` line, all of the macros which require pdf drawing won't work, as well as possibly some other macros.
-
-The pdfMsym package also provides a relatively easy-to-use interface for creating new symbols.
-Read the documentation (pdfmsym-doc.pdf) for more details.
-
+Read the documentation (documentation.pdf) for more details.
 The pdfMsym package is provided under the MIT license.
 
-Compile the documentation via `pdftex pdfmsym-doc.tex`.
+Compile the documentation via `pdftex pdfsym-doc.tex`.
 
 The pdfMsym package was created and is maintained by Slurp who can be reached via email: slurper04@gmail.com
 Please report any bugs or issues with the package, doing so would be greatly appreciated.
-Suggestions for features to add to the package will also be greatly appreciated.
 
-Thank you for using pdfMsym,

+## version 1.1.1
+pdfMsym version 1.1.1 fixed a bug which would cause an error when reading a PDF created with pdfMsym in certain PDF readers.
+
+It also added support for creating arbitrarily stroked arrows, as well as some more arrows.
+
+Lastly, some of the lineheads were altered.
