+# About LDMicro
+LDmicro is a ladder logic editor, simulator and compiler for 8-bit microcontrollers. It can generate native code for Atmel AVR and Microchip PIC16 CPUs from a ladder diagram.

 # LDMicro for Linux
-This is a linux compatible version of the original LDMicro program.
+This is a Linux compatible version of the original LDMicro program for windows created by Jonathan Westhues, and proted to Linux under [FOSSEE](https://github.com/FOSSEE) fellowship program 2018 by [Ramana R](https://github.com/Rr42) and [Rohit I](https://github.com/NatsuDrag9), under the mentorship of [Akshay C](https://github.com/akshay-c).

+# Instructions

+# Building LDMicro for Linux
+LDmicro for Linux is built using MinGW C++ compiler. 
+
+### Building the Makefile
+In order to generate the Makefile that can be used to compile the project, simply run the following commands from a terminal in the project directory:
+```
+cd /LDmicro/
+mkdir build
+cd build/
+cmake ..
+```

+### Building LDMicro for Linux
+Simply run `make` in the build directory of the project to compile.
+
+_Note_: In order to compile the Makefile must first be generated (see [Building the Makefile](#building-the-makefile)).
+
+Multiple Perl Scripts are executed during the build phase. In order to execute these scripts, you need perl. This project uses ActivePerl Community Edition, which can be obtained from the following website:
+
+http://www.activestate.com/activeperl
+
+or install the perl packages from the terminal (see [External package dependencies](#external-package-dependencies)).
