 Pmacs is an Emacs-like editor written entirely in Python. It is designed to have
-maximally correct and powerful support for syntax highlighting, indenting, etc.
+maximally correct and powerful support for syntax highlighting, to support
-and to be extensible in python.
+various methods of automatically indenting lines, and to be extensible in
+python.
+
+Pmacs is available to you under the GPL version 2.
+
+While the general interface of pmacs is related to emacs, there was explicitly
+no attempt to support all emacs' functions, emacs' underlying data structures,
+or even high-level. There is not currently a formalized "public API" for pmacs,
+although some parts are "more public" than others. The code is somewhat
+commented, although currently there is only one author. Buyer beware!
 
 Requirements:
-=============
     1. python 2.3 or higher
     2. ncurses
 
 Optional Dependencies:
-======================
     1. ispell
     2. aespipe
     3. perl
     4. ctags
+    5. cvs
+    6. svn
+
+Quick Start Guide:
+    1. Download and unpack the pmacs tarball file. After this, there should be
+        a directory called "pmacs2" somewhere in your filesystem. It doesn't
+        matter where you put this. We'll call the full path to this directory
+        PMACSDIR; in future steps substitute the actual path for this symbol.
+    2. Create a symlink to PMACSDIR/application.py and put it in a directory
+        listed in your $PATH (~/bin, /usr/local/bin, and /usr/bin are all good
+        candidates). You can name this symlink whatever you want; I use "pmc".
+    3. Try editing a file, by typing "pmc FILE" where FILE is the path to the
+        file you want to edit.
+    4. Edit the file!
+
+        You can type Control-c and then Meta-h to get a list of all the
+        available actions and which key(s) perform them. Type Control-x k to get
+        out of the "help buffer". If you have used emacs, many (but not all) of
+        these keybindings should seem familiar.
+
+    5. To save your changes, type Control-x Control-s. To quit, type Control-x
+        Control-c. To quit without saving changes, type Control-c Control-c.
+
+There is currently no other documentation (besides comments in the code). Good
+luck!
