+.Sh NAME
+.Nm noice
+.Nd small file manager
+.Sh SYNOPSIS
+.Nm noice
+.Op Ar dir
+.Sh DESCRIPTION
+.Nm
+is a simple and efficient file manager that gets out of your way
+as much as possible.  It was initially implemented to be controlled
+with a TV remote control.
+.Pp
+.Nm
+supports both vi-like and emacs-like key bindings in the default
+configuration.  The default key bindings are described below;
+their functionality is described in more detail later.
+.Pp
+.Bl -tag -width "h | Left | BackspaceXXXX" -offset indent -compact
+.It Ic k | Up | C-p
+Move to previous entry.
+.It Ic j | Down | C-n
+Move to next entry.
+.It Ic Pgup | C-u
+Scroll backwards one page.
+.It Ic Pgdown | C-d
+Scroll forwards one page.
+.It Ic l | Right | C-m
+Open file or enter directory.
+.It Ic h | Left | Backspace
+Back up one directory level.
+.It Ic / | &
+Filter view (see below for more details).
+.It Ic !
+Spawn shell in current directory.
+.It Ic c
+Change into the given directory.
+.It Ic q
+Quit
+.Nm .
+.Sh CONFIGURATION
+.Nm
+is configured by modifying
+.Pa config.h
+and recompiling the code.
+.Pp
+The file associations are specified by regexes
+matching on the currently selected filename.  If a match is found the associated
+program is executed with the filename passed in as the argument.  If no match
+is found the program less(1) is invoked.  This is useful for editing text files
+as one can use the 'v' command in less(1) to edit the file in $EDITOR.
+.Pp
+See the examples section below for more information.
+.Sh FILTERS
+Filters allow you to use regexes to display only the matched
+entries in the current directory view.  This effectively allows
+searching through the directory tree for a particular entry.
+.Pp
+Filters do not stack on top of each other.  They are applied anew
+every time.
+.Pp
+To reset the filter you can use the match-any regex (i.e. '.').
+.Sh EXAMPLES
+The following example shows one possible configuration for
+file associations.  This is the default configuration for
+.Nm .
+.Bd -literal
+struct assoc assocs[] = {
+        { "\\.(avi|mp4|mkv|mp3|ogg|flac)$", "mplayer" },
+        { "\\.(png|jpg|gif)$", "feh" },
+        { "\\.(html|svg)$", "firefox" },
+        { "\\.pdf$", "mupdf" },
+        { "\\.sh$", "sh" },
+        { ".*", "less" },
+};
