+
+## Description
+We need to ensure the compatibility with the next version of OpenSearch vX.X.
+This update is still being discussed, but we need to be aware of potential issues.
+
+For that, we need to:
+
+- [ ] Review opensearch's release notes. 
+- [ ] Identify improvements and potential impact.
+- [ ] Create new development branch.
+- [ ] Develop a testing environment to verify our components would work under this new build.
+

+## Wazuh indexer integrations
+
+This folder contains integrations with third-party XDR, SIEM and cybersecurity software. 
+The goal is to transport Wazuh's analysis to the platform that suits your needs.
+
+### Amazon Security Lake
+
+Amazon Security Lake automatically centralizes security data from AWS environments, SaaS providers, 
+on premises, and cloud sources into a purpose-built data lake stored in your account. With Security Lake, 
+you can get a more complete understanding of your security data across your entire organization. You can 
+also improve the protection of your workloads, applications, and data. Security Lake has adopted the 
+Open Cybersecurity Schema Framework (OCSF), an open standard. With OCSF support, the service normalizes 
+and combines security data from AWS and a broad range of enterprise security data sources.
+
+##### Usage
+
+A demo of the integration can be started using the content of this folder and Docker.
+
+```console
+docker compose -f ./docker/amazon-security-lake.yml up -d
+```
+
+This docker compose project will bring a *wazuh-indexer* node, a *wazuh-dashboard* node, 
+a *logstash* node and our event generator. On the one hand, the event generator will push events 
+constantly to the indexer. On the other hand, logstash will constantly query for new data and
+deliver it to the integration Python program, also present in that node. Finally, the integration 
+module will prepare and send the data to the Amazon Security Lake's S3 bucket. 
+<!-- TODO continue with S3 credentials setup -->
+
+For production usage, follow the instructions in our documentation page about this matter.
+(_when-its-done_)
+
+As a last note, we would like to point out that we also use this Docker environment for development.
+

+
+TBD
