 # self-hosted-runners
-This repository is about deploying self hosted runners. 
-We create instances at **runtime** with `terraform-openstack`, we then use ansible to configure those users( so they will become runners). After that we assign them some jobs from the githubactions using labels. Once all jobs terminated we then delete all created ressources using `terraform`. 
+This repository contains information on deploying self-hosted runners. The following technologies are covered/used in this project: Ansible (for configuration), Terraform and OpenStack for provisioning, Pipelines (GitHub Actions) and shell scripts for automation, and Python for the implementation of a Terraform plugin.

+I'm using Terraform and Openstack to create instances at **runtime**, and then I'm configuring those instances to become runners with ansible. After that, I assign them jobs from the Pipeline using labels. After all jobs have been completed, I use 'terraform' to delete all resources that have been created.
