+# Loki
+
+## From the [Loki](https://github.com/grafana/loki) GitHub repository
+
+Loki is a horizontally-scalable, highly-available, multi-tenant log aggregation system inspired by Prometheus. It is designed to be very cost effective and easy to operate.
+
+## Working with Loki
+
+To get logs "into" Loki you need a scrape agent, such as official [Promtail](https://grafana.com/docs/loki/latest/clients/promtail/installation/) or a library for your app that can push logs through HTTP endpoint (gRPC endpoint is disabled in Docker enviroment by default)
+
+## Resource consumption
+
+As this egg sets up Loki in single node mode, it can consume a lot of disk space really fast. It is possible to setup different kind of storages for different parts of Loki files. For further information refer to official [Loki documentation](https://grafana.com/docs/loki/latest/operations/storage/).
+
+To get started, you can go with a minimum of 3GB RAM and >=2.5GB disk space.
+
+Keep in mind that those numbers can grow pretty quick!
+
+## Server Ports
+
+Ports required to run the server in a table format.
+
+| Port        | default |
+|-------------|---------|
+| Loki server | 3100    |
