+# Overview
+
+This feature of `mapt` allows to setup hosts deployed by it as a Github Self Hosted Runner, which can then be directly used for running github actions jobs.
+It benefits from all the existing features that `mapt` already provides, allowing to create self hosted runners that can be used for different QE scenarios.
+
+## Providers and Platforms
+
+Currently it allow to create self hosted runners on AWS (Windows Server, RHEL) and Azure (Windows Desktop)
+
+### Prerequisite
+
+To register a Self Hosted Runner for a repository or a Github organization, the runner program needs a registration token, which can be obtained by requesting the
+Github API.
+
+* [Information for requesting a token to register a runner for an Organization]()
+* [Information for requesting a token to register a runner for a repository]()
+
+After obtaining the token we can invoke `mapt` with it to deploy a VM as a Self hosted runner.
+
+For example to add a runner to this repository, we can use the following `curl` command to request a token:
+
+```
+% curl -L \
+  -X POST \
+  -H "Accept: application/vnd.github+json" \
+  -H "Authorization: Bearer <github_personal_access_token>" \
+  -H "X-GitHub-Api-Version: 2022-11-28" \
+  https://api.github.com/repos/redhat-developer/mapt/actions/runners/registration-token
+```
+The Response from this `POST` request will be:
+
+```
+{
+  "token": "ACDZL3QXEIC73UXBDGSEYEI",
+  "expires_at": "2024-07-12T19:01:48.478+05:30"
+}
+```
+
+### Operations
+
+After getting the required token, we need to also decide what we are going to call this runner, the desired name can be passed to the `mapt` command using the
+`--ghactions-runner-name` flag.
+
+The full URL of the repository or the github organization also needs to be passed using the `--ghactions-runner-repo` flag.
+
+To deploy a Windows runner on the Azure provider, we can use the following command:
+
+```
+% mapt azure windows create --spot \
+    --install-ghactions-runner \
+    --ghcations-runner-token="ACDZL3QXEIC73UXBDGSEYEI"
+    --ghcations-runner-name "az-win-11"
+    --ghcations-runner-repo "https://github.com/redhat-developer/mapt"
+    --project-name mapt-windows-azure \
+    --backed-url file:///Users/tester/workspace \
+    --conn-details-output /Users/tester/workspace/conn-details
+```
