+# TSALIS
+*TSALIS* is a text user interface (TUI) designed to communicate with *SALIS*.
+Its only dependencies are ncurses and the *SALIS* library itself. It should be
+portable enough and should run easily in any terminal environment.
+
+## Building instructions
+You'll need nothing but a C compiler (C89). You must build the program and link
+it with *SALIS* (e.g. *libsalis.a*) and ncurses. A sample makefile
+(Makefile) is provided for GNU Make. You can also just run the `make` command
+inside the salis directory and it will automate the building and linking of
+both the library and this application. Feel free to edit both makefiles as
+needed. If you run into any difficulties, please let me know!
+
+## List of commands
+### Command-line arguments
+You may run *TSALIS* from the terminal in any of these three ways (arguments
+are being represented by *XX*). Note that, upon exit, *SALIS* automatically
+generates a save (by default called *defsim*). This save file may be freely
+renamed (any name 10 characters or shorter) and reloaded as needed.
+
+|Arguments      |Action                                                                         |
+|:--------------|------------------------------------------------------------------------------:|
+|tsalis         |If file *defsim* exists in directory, loads simulation from that file.         |
+|tsalis         |If file *defsim* does not exist, creates new simulation (memory size 2^16).    |
+|tsalis n*XX*   |Creates new simulation with memory size 2^*XX*.                                |
+|tsalis l*XX*   |Loads simulation from file named *XX*.                                         |

+### Console commands
+The console opens up when 'c' is pressed. Commands, with their respective

+control some aspects of the simulation. Parameters here are represented by

+cell is colored according to the following legend:
