 # Building MultICE
 MultICE uses a relatively simple build system. It has been tested on Arch Linux, Debian Linux, OpenOS and Plan9k.
 ## 1. Choose modules.
-The system is made out of modules from the `modules/` directory. When you run the build script, it assembles them, and optionally optomises the code for space.  
+The system is made out of modules from the `modules/` directory. When you run the build script, it assembles them, and optionally optimises the code for space.  
 There are a number of preconfigured module sets in the `config/` directory, and you can of course you can write your own.
 
 The build system defaults to a file called `modules.cfg` in the current directory. You can specify a config file using `--modconfig=file.cfg`.

+# skex2
+
+## interactive line editor
+
+skex2 is a simple but functional line editor for MultICE.
+
+### invocation
+
+To start skex2, simply run skex(filename) from the Lua prompt.
+
+### usage
+
+Generally, commands and arguments are entered in the form of `command argument1 argument2 argument3` with the exception of inline execution, which is in the form of `!lua code here`.
+
+If skex does not understand what you mean, it will output a line with a question mark.
+
+### commands
+
+#### q - quit skex2
+
+Exits the program.
+
+#### l \[start\] \[end\] - list contents
+
+Output the lines from start to end, inclusive.
+
+#### f \[filename\] - set the filename
+
+This sets the filename to be used for I/O, or prints the current one.
+
+#### r \[filename\] - load file
+
+Reads from *filename* or the current set via **f**
+
+#### w \[filename\] - write to file
+
+Writes to *filename* or the current set via **f**
+
+#### p \[line\] - print or set current line
+
+As skex2 is a line editor, your pointer is a line, and this either prints the current one or sets a new one.
+
+#### a \[line\] - append to buffer
+
+Appends lines after the current line or *line* until a line with only . is entered.
+
+#### i \[line\] - insert into buffer
+
+Inserts lines before the current line or *line* until a line with only . is entered.
+
+#### s \[line\] - replace line
+
+Removes the current line or *line* and enters insert mode
+
+#### e - executes the contents of the buffer
+
+Basically converts it into one big string and loads it.
