+# TikZ-trackschematic Symbology
+
+------------
+
+# Usage
+
+The folder "symbols_tikz" contains the primary geometric form of each symbol.
+The symbols are:
+  - without any labels
+  - in a forward direction (if applicable)
+  - added with an anchor or two (a small magenta dot) for the placement along the track(s)
+
+Run the script "generate_symbols.sh" to generate the PDF, PNG, and SVG version from the files in the "symbols_tikz" folder.
