 ## Usage
 
 
-### As A Script
+### As A Command Line Utility
 
 The STIX-Shifter comes with a bundled script which you can use to translate STIX Pattern to a native datasource query. It can also be used to translate a JSON data source query result to a STIX bundle of observable objects. You can also send query to a datasource by using a transmission option.

+In order to build `stix-shifter` packages from source follow the below prerequisite steps:
    1. Go to the stix-shifter parent directory
-   2. Generate latest requirements.txt: `python3 generate_requirements.py`
-   3. Install the dependencies in your python 3 environment: `pip install -r requirements.txt` 
-   4. Alternatively you can create a Python 3 virtual environemnt:
-       `virtualenv -p python3 virtualenv && source virtualenv/bin/activate && pip install -r requirements-dev.txt`
+   2. Optionally, you can create a Python 3 virtual environemnt:
+       `virtualenv -p python3 virtualenv && source virtualenv/bin/activate`
+   3. Run setup: `python3 setup.py install`
+
+
+### Running From the Source
+
+You may also use `python3 main.py` script. All the options are the same as "As a command line utility" usage above.
+
+Example:
+
+```
+python3 main.py translate qradar query {} "[ipv4-addr:value = '127.0.0.1']" {}
+```
+
+In order to run `python3 main.py` from the source follow the below prerequisite steps:
+   1. Go to the stix-shifter parent directory
+   2. Optionally, you can create a Python 3 virtual environemnt:
+       `virtualenv -p python3 virtualenv && source virtualenv/bin/activate`
+   3. Run setup to install dependancies: `INSTALL_REQUIREMENTS_ONLY=1 python3 setup.py install`. 
+
+**Note:** setup.py only installs dependencies when INSTALL_REQUIREMENTS_ONLY=1 directive is used. This option is similar to `python3 generate_requirements.py && pip install -r requirements.txt`
