+
+Gravity (small `g`) measurement data processing framework written in Python.
+
+The goal of the gMeterPy is to create an open source software to process 
+raw data from all types of gravimeters.
+
+**The project is in the early planning and development stage.**
+
+About
+-----
+*gMeterPy* is an open source and free Python library for processing 
+measurement data from gravimeters, which are used for gravity field surveys 
+in geodesy, geophysics and other branches of Earth and planetary sciences. 
+The main intention is to go as deep as possible in processing **raw** data 
+from scratch, as well as to support all types of instruments, 
+corrections, common file formats and processing procedures.
+
+Install
+-------
+
+To install ``gMeterPy`` simply use ``pip`` as usual: 
+
+.. code:: bash
+
+    pip install gmeterpy
+
+Or with `git`:
+
+.. code:: bash
+
+    git clone https://github.com/opengrav/gmeterpy.git && cd gmeterpy 
+    pip install .
