+# A Modern Fortran-based Parser
+
+<!-- Thanks for visiting [The Markdown Guide](https://www.markdownguide.org)!
+
+This Markdown cheat sheet provides a quick overview of all the Markdown syntax elements. It can’t cover every edge case, so if you need more information about any of these elements, refer to the reference guides for [basic syntax](https://www.markdownguide.org/basic-syntax) and [extended syntax](https://www.markdownguide.org/extended-syntax). -->
+
+## Get the code
+  The parser uses a modified libfdf library. This is included in this repository as a submodule. To clone the entire project, do
+
+  `git clone --recurse-submodules https://github.com/TREX-CoE/iof08.git`
+
+
+## Compilation
+  The project contains two directories (a) modified-libfdf and (b) parser.
+
+  - Compile and install the modified-libfdf using the following set of commands
+    - `./configure --prefix=/usr/local FC=ifort CC=icc `
+    - `make`
+    - `sudo make install`
+    - `make check`
+
+
+## Integrate parser in your code
+
+
+
+### Features of the parser (including inheritance from libfdf)
+
+- Include another input file for parser to read using:
+
+` %include    global.inp`
+
+- Include a data file for parser to read using:
+
+` load label filename`
+
+Here, depending upon the label, parser will provide the filename. For example,
+
+` load basis cc-pvtz.gbs`
+
+- Read molecular coordinates directly from the input file using 
+
+```perl
+%block molecule 
+12
+ #benzene comment
+ C    0.00000    1.40272  0
+ H    0.00000    2.49029  0
+ C   -1.21479    0.70136  0
+ H   -2.15666    1.24515  0
+ C   -1.21479   -0.70136  0
+ H   -2.15666   -1.24515  0
+ C    0.00000   -1.40272  0

+ H    2.15666   -1.24515  0
+ C    1.21479    0.70136  0
+ H    2.15666    1.24515  0
+%endblock
+```
+
+- Read molecular coordinates from an external .xyz file using 
+
+` %block molecule < caffeine.xyz `
+
+
+- Group certain keywords using the %module construct
+
+```perl
+%module DMC
+    tau     =   0.04
+    etrial  = -15 Ha
+%endmodule
+```
+
+- Logical variables accept true, TRUE, T, 1, .true. as valid keywords for true
+` optimize_wavefunction 	true`
