+This is `htop`, an interactive process viewer.
+It requires `ncurses`. It is developed primarily on Linux,
 but we also have code for running under FreeBSD and Mac OS X
 (help and testing are wanted for these platforms!)
 
 This software has evolved considerably over the years,
 and is reasonably complete, but there is always room for improvement.

 Compilation instructions
 ------------------------
 
 This program is distributed as a standard autotools-based package.
-See the INSTALL file for detailed instructions, but you are
-probably used to the common `./configure`/`make`/`make install` routine.
+See the [INSTALL](/INSTALL) file for detailed instructions, but you are
+probably used to the common routine:
+
+    ./autogen.sh && ./configure && make
+
+By default `make install` will install into `/usr/local`, for changing
+the path use `./configure --prefix=/some/path`.
+
+See the manual page (`man htop`) or the on-line help ('F1' or 'h'
+inside `htop`) for a list of supported key commands.
 
-When fetching the code from the development repository, you need
-to run the `./autogen.sh` script, which in turn requires autotools
-to be installed.
+If not all keys work check your curses configuration.
 
-See the manual page (man htop) or the on-line help ('F1' or 'h'
-inside htop) for a list of supported key commands.
