-The workflow `build-and-send.yaml` allows the user to build the diploma thesis via a github workflow.
+## General
-Adapt it to meet your needs.
 
-Note that sending the thesis, and therefore automated emails, using a school email address is not supported. It is best to use an email address that does not correspond to your school email address.
+The workflow `Build and send diploma thesis` allows the user to build the diploma thesis via a github workflow and send it to a Microsoft Teams channel.
+
+## Setup
+
+### Microsoft Teams
+
+// TODO
+
+### GitHub
+
+#### Settings
+
+In your GitHub Repository you first need to create the secrets the action needs. For that, go to the `Settings` Tab of your Repository and there under the section `Security` go to `Secrets and variables` and there to the option of `Actions`
+
+![Github Headbar](github-repo-settings.png)
+
+Now click on the button `New repository secret` to create the GitHub action secrets.
+
+![Github Headbar](github-action-secret-creation.png)
+
+Here you enter the names of the secrets and their values corresponding to the following table. After inserting one new secret click `Add secret`.
+
+| Name | Secret |
+|-|-|
+| MAIL | Your email address from which the diploma thesis should be sent from  |
+| MAIL_PASSWORD | The password for MAIL |
+| SMTP_PORT | The SMTP port corresponding to SMTP_SERVER |
+| SMTP_SERVER | The SMTP Server for your email address |
+| TEAMS_MAIL | The Teams channel email from the channel the diploma thesis should be sent to |
+
+Now it should look like this:
+
+![Github Headbar](github-action-secret-overview.png)
+
+#### Repo
+
+Now create a folder ```.github/workflows``` in the root of your repository and copy and paste the file ```diploma-thesis.yml``` into it. Push it and everything is set.
+
+### Notes
+
+- Sending the diploma thesis, and therefore automated emails, using a school email address is not supported. It is best to use an email address that does not correspond to your school email address.
