+## Material for MkDocs
+
+Documentation is [MkDocs-material](https://squidfunk.github.io/mkdocs-material/) which is a Markdown documentation framework written on top of [MkDocs](https://www.mkdocs.org/).
+
+1. For initial setup of virtual environment:
+
+   ```bash
+   virtualenv venv
+   source venv/bin/activate
+   pip install -r requirements.txt
+   ```
+
+2. To activate virtual environment:
+
+   ```bash
+   source venv/bin/activate
+   pip install -r requirements.txt
+   ```
+
+   In the future you can update using:
+
+   ```bash
+   pip3 install -r requirements.txt -U 
+   ```
+
+3. Use ***mkdocs** to preview locally:

+# JTS Topology Suite
+
+The JTS Topology Suite (JTS) is an open source Java software library
+that provides an object model for planar geometry together with a set of
+fundamental geometric functions. JTS conforms to the Simple Features
+Specification for SQL published by the Open GIS Consortium. JTS is
+designed to be used as a core component of vector-based geomatics
+software such as geographical information systems. It can also be used
+as a general-purpose library providing algorithms in computational
+geometry.
