+# Universal Worker Service Framework
+
+Implemented in Django and djangorestframework the uws_framework is meant to enable UWS compatibility of your task
+server. The UWS is a IVOA specification for async services _(please find more details
+at https://ivoa.net/documents/UWS/20161024/REC-UWS-1.1-20161024.html)_
+
+
+## Quick start
+The following assumes that you are in the uws_server directory and that such directory is in the python path of your 
+active python environment.
+Before deploying the service you have to create the database. Such operation is completely automatic thanks to Django
+all you have to do is specify the database server you want to use in the database section of 
+`uws_server/settings.py`
+
+After that the migrations have to be created and applied. This can be done with 
+```
+$ python manage.py makemigrations
+$ python manage.py migrate
+```
+
+To spawn a test server you can run the command:
+```
+$ python manage.py runserver
+```
+
+Executing the above operations will only enable the rest interface of the UWS framework. To completely use the service
+you have to execute also the job scheduler. To do so you have to execute the script
+
+```
+$ bin/job_scheduler.py
+```
+
+As this is a framework nothing is implemented to the actual execution of the any job. To implement the execution method
+you have to implement a task adapter and export it in the `settings.py` file.
+An abstract class is available at the path `uws_procedures/tasks.py`. Furthermore, a test implementation is in `test_tasks/tasks.py`.
