-fx2lafw is a free/libre/open-source firmware for logic analyzers based on
-the Cypress EZ-USB FX2(LP) chip.
+The sigrok project aims at creating a portable, cross-platform,
+Free/Libre/Open-Source signal analysis software suite that supports various
+device types (such as logic analyzers, oscilloscopes, multimeters, and more).
 
-It is licensed under the terms of the GNU GPL (version 2 or later), and uses
-additional helper code (fx2lib), licensed under the GNU LGPL (version 2.1
-or later).
+sigrok-firmware-fx2lafw is a Free/Libre/Open-source firmware for logic

+
+
+Status
+------
+
+sigrok-firmware-fx2lafw is in a usable state and has had official
+tarball releases.
 
 
 Requirements
 ------------
 
- - In order to build fx2lafw you need the 'sdcc' compiler.
+ - git
+ - make
+ - autoconf >= 2.63
+ - automake >= 1.11
+ - sdcc (>= 2.9.0)
+
+Notes:
+
+ - In order to build fx2lafw you need the 'sdcc' compiler (>= 2.9.0).
    On Debian you can install it via:
 
      $ apt-get install sdcc
 
+   This project has been tested to work with sdcc 2.9, 3.0, 3.1, and 3.2.
+
  - You need libsigrok >= 0.1.1 in order to make use of fx2lafw. Earlier
    versions didn't have support for FX2 devices using this firmware.
 
 
-Building
---------
+Building and installing
+-----------------------
 
-  $ git clone git://sigrok.git.sourceforge.net/gitroot/sigrok/fx2lafw
-  $ cd fx2lafw
-  $ make
+In order to get the sigrok-firmware-fx2lafw source code and build it, run:
 
+ $ git clone git://sigrok.org/sigrok-firmware-fx2lafw
+ $ cd sigrok-firmware-fx2lafw
+ $ ./autogen.sh
+ $ ./configure
+ $ make
 
-Usage
------
+For installing sigrok-firmware-fx2lafw:
 
-Copy the generated *.fw file for your device (e.g. fx2lafw-saleae-logic.fw)
-into the $prefix/share/sigrok-firmware directory (create it, if needed).
+ $ make install
 
-Replace $prefix with the install prefix of sigrok, e.g. /usr or /usr/local.
+The generated *.fw files are installed into /usr/local/share/sigrok-firmware.
 
-Example (assuming /usr/local as $prefix):
+You can override the install location like this:
 
-  $ sudo mkdir /usr/local/share/sigrok-firmware
+ $ ./configure --prefix=/usr
 
-  $ sudo cp hw/saleae-logic/build/fx2lafw-saleae-logic.fw \
-            /usr/local/share/sigrok-firmware
+See INSTALL or the following wiki page for more (OS-specific) instructions:
 
-The sigrok frontends (command-line or GUI) will automatically search for
-firmware files there and automatically use/upload them.

+There are also pre-built firmware files that can be used without having
+to build them from source. You can download those from SourceForge:
