-# Integrated Semantic Framework (intsem.fx)
+# Integrated Semantic Framework
 
 A Python 3 implementation of the [Integrated Semantic Framework](https://osf.io/9udjk/) that provides computational deep semantic analysis by combining structural semantics from construction grammars and lexical semantics from ontologies in a single representation.
 
-# Install
+`coolisf` is only a back-end semantic parsing module that runs on command-line interaface or in Python programs.
+If you want a friendly graphical user interface, please use [visualkopasu](https://github.com/letuananh/visualkopasu/).
 
-`coolisf` only works on Linux distributions at the moment (built and tested on Fedora and Ubuntu Linux). 
-
-- Install `coolisf` package from [PyPI](https://pypi.org/project/coolisf/) using pip
-
-```
-pip install coolisf
-```
-
-- Create coolisf data folder at `/home/user/local/isf/data`
-- Download ace-0.9.26 binary from https://osf.io/x52fy/ to `/home/user/bin/ace`. Make sure that you can run ace by
-
-```bash
-[isf]$ ~/bin/ace -V
-ACE version 0.9.26
-compiled at 18:48:50 on Sep 14 2017
-```
-
-- Install [lelesk](https://pypi.org/project/lelesk/) and yawlib with data
-- Download coolisf lexical rules database from https://osf.io/qn4wz/ and extract it to `/home/user/local/isf/data/lexrules.db`
-- Download grammar files (erg.dat, jacy.dat, virgo.dat, etc.) and copy them to `/home/user/local/isf/data/grammars/`
-
-The final data folder should look something like this

+## Install
+
+The `coolisf` package itself is available on [PyPI](https://pypi.org/project/coolisf/) and it can be installed using pip
+
+```bash
+pip install coolisf
+```
+
+However, it can be tricky to acquire all the required components and data. Please find version specific prerequisites and installation instructions on coolisf's [official Github release page](https://github.com/letuananh/intsem.fx/releases).
