+<h2>Azaion AI</h2>
+
+<p>
+  Azaion AI is a worker written on cython (c-compilable python) which listens to socket and rabbit queue.
+It accepts commands om a format:
+
+ - CommandType: Inference / Load
+ - Filename
+
+And correspondingly do inference or just load encrypted file from the API.
+Results (file or annotations) is putted to the other queue, or the same socket, depending on the command source.

+
+<h3>Install dependencies</h3>
+```
+Make sure that your virtual env is installed with links to the global python packages and headers, like this:
+python -m venv --system-site-packages venv
+This is crucial for the Build because build needs Python.h header and other files.
