+Chips using UU-encoded protocols (e.g., LPC1700 family) are not supported.
+Other NXP devices with 1 kB sector sizes may work by adding their configuration to the lpctools_parts.def file.
+The configuration file is identical to that used by the [lpctools project](http://git.techno-innov.fr/?p=lpctools).
 
 ## Usage
+### Erase Entire Flash
+```bash
+isp_programmer --device /dev/ttyUSB0 -b 9600 -crystal_frequency 12000 masserase
+```

 ## Installation
 ### pypi
-    pip install ISPProgrammer
+```bash
+pip install isp_programmer
+```
+
 ### From Source
-isp-programmer is a python3 package and can be installed using pip.
-Clone the repository, enter the directory with setup.py in it and run
+```bash
+git clone https://github.com/snhobbs/isp-programmer.git
+cd isp-programmer
 pip install .
+```
+
 The default location for the configuration file is at /etc/lpctools_parts.def.
 The file can either be copied there or the path passed in when calling the tool
-with the --config_file/-f flag.
-
-    1. cd isp-programmer
-    2. pip install .
-    3. cp lpctools_parts.def /etc
-
+with the --config_file/-f flag. If none is given or found then the default parts are still available.
