+# TL866
+Open source firmware and utilities for Minipro TL866xx series of chip programmers
+
+This project's scope is dealing with the firmware within the TL866 
+itself.  It includes software for dumping, reprogramming, and 
+manipulating the firmware.  Schematics and discussion of internal 
+operations are also here.
+
+These programs are not for using the TL866 to read and write chips.  Use 
+https://github.com/vdudouyt/minipro for that.
+
+
+## Installation of the TL866 Updater on Linux
+
+### Install build dependencies
+
+#### Debian/Ubuntu
+```nohighlight
+sudo apt-get install build-essential pkg-config git libusb-1.0-0-dev libqt4-dev
+```
+
+### Checkout source code and compile 
+```nohighlight
+git clone https://github.com/radiomanV/TL866
+cd TL866/QT
+qmake
+make
+sudo cp TL866_Updater /usr/local/bin
+```
+
+### Udev configuration (recommended)
+If you want to access the programmer as a regular user, you'll have to 
+configure udev to recognize the programmer and set appropriate access 
+permissions.  These are the same rules as are available with 
+https://github.com/vdudouyt/minipro.  If you already installed the rules 
+there, you don't need to do it again here.
+
+#### Debian/Ubuntu
+```nohighlight
+sudo cp udev/debian/60-minipro.rules /etc/udev/rules.d/
+sudo udevadm trigger
+```
+You'll also have to add your regular user to the `plugdev` system
+group:
+```nohighlight
+sudo usermod -a -G plugdev YOUR-USER
+```
+Note that this change will only become effective after your next
+login.
+
+#### CentOS 7
+```nohighlight
+sudo cp udev/centos7/80-minipro.rules /etc/udev/rules.d/
+sudo udevadm control --reload-rules
+```
+The CentOS rules file currently make the programmer device writable for 
+all users.
