+## Ingest STIX
+
+Python script to ingest STIX files on MISP.
+
+### Requirements
+
+There are a few requirements for this little python script to run, which are included in the MISP requirements:
+- PyMISP
+- Python 3.6+ (because PyMISP is Python 3.6+)
+- Your API key
+
+The recommended python setup for MISP is described within [the following documentation](https://www.circl.lu/doc/misp/updating-python/).
+
+### Description
+
+The aim of this small piece of code is to ingest STIX files.
+
+In order to ingest STIX data into MISP, there are 2 end points to query, `/events/upload_stix` for STIX 1, and `/events/upload_stix/2` for STIX 2.  
+The content of the STIX file to ingest has then to be passed in the body of the query.
+
+The equivalent is available in PyMISP with the `upload_stix` method. The only difference is instead of passing the STIX content, the filename(s) of the file(s) to import are passed.
+
+MISP creates then an event for each file ingested, using the [stix import](https://github.com/MISP/MISP/blob/2.4/app/files/scripts/stix2misp.py) or [stix2 import](https://github.com/MISP/MISP/blob/2.4/app/files/scripts/stix2/stix2misp.py) scripts.
+
+### Usage
+
+Depending of the python environment set in your MISP server, you will have to use the correct python command in order to be sure to reach the correct environment containing all the required libraries and dependencies:
+- The recommended environment installed by default in most of our installation scripts, and virtual machine is a virtualenv available using `/var/www/MISP/venv/bin/python`
+- If any other python environment is set instead, use the corresponding command. As an example, the built-in python3 provided with most of the linux distribution is available with a simple `python3`
+**Please replace the python command in the next examples with your own setting if needed**
+
+In order to connect to MISP, we need an URL and an API key.  
+You can either pass those parameters when you call the `ingest_python.py` script, or put them within the `setup.json` file that is passed by default to the script, or event use another setup file as long as it contains the same required fields:
+- `misp_url`: the URL of your MISP server
+- `misp_key`: your MISP API key
+- `misp_verifycert`: (`true` or `false`) to check or not the validity of the certificate
+
+We also require here a STIX version and the path to the files to ingest (**Please use file names instead of directory names**)
+
+As just mentioned, the setup file is used by default, and it avoids empty value issues for the required parameters. It is thus possible to simply run the following:
+```
+# STIX 1
+python3 ingest_stix.py --version 1 --path _PATH_TO_YOUR_FILES_/stix_files*.xml
+
+# STIX 2
+python3 ingest_stix.py --version 2 --path _PATH_TO_YOUR_FILES_/stix_files*.json
+```
+
+But you can also overwrite one of the required MISP setups:
+```
+# Overwrite the SSL verification
+python3 ingest_stix.py --version 1 --path _PATH_TO_YOUR_FILES_/stix_files*.xml --misp_verifycert
+
+# Simply define all the parameters without using the setup file
+python3 ingest_stix.py --version 1 --path _PATH_TO_YOUR_FILES_/stix_files*.xml --misp_url _MISP_URL_ --misp_key _YOUR_API_KEY_ --misp_verifycert
+```
