 - **Project** - one or more deployments grouped together (e.g. started via docker-compose)
 - **Deployment** - one and only one deployed service
 
+## Requirements
+
+Exoframe CLI is not particularly demanding and consumes at max ~50mb of RAM.  
+Most intensive task from CLI side is packaging the project and streaming that to the server - it doesn't affect RAM usage that much and mostly relies on CPU and network.
+
+Running Exoframe server on its own also doesn't require too much resources:
+- Exoframe Server consumes ~50mb of RAM
+- Traefik started along with server consumes ~60mb of RAM
+
+Be aware though - execution of deployments will result in (1) new Docker images being built and (2) new Docker containers being started.  
+Depending on your project's complexity, this might require significant amount of resources during both steps resulting in failed deployments (note: if Docker goes out-of-memory during build, you will not get any specific error - just a failed deployment).  
+It is recommended to run Exoframe on a server with at least 1GB of RAM.
