 This is CyberInfo's public Gitea instance. Feel free to download and use any
-code you find in the public repositories.

-If you wish to contribute to any of these projects, you can either send me an
-email with a patch by following these instructions.
+If you wish to contribute to any of these projects, you can send me an email
+with a patch by following these instructions:
 
-* Send me email with a patch, and I'll apply it. See the instructions below.
+1. First, clone the repository to your local computer. For example:  
+   `git clone https://git.cyberinfo.se/jackbenny/autotape.git`
 
-## Sending patching by email
+2. Then, make your changes to the code.
 
+Now it's time to prepare the patch. Run the following commands:
+
+```bash
+git add <file-with-changes>
+git commit -m "Write a good commit message here"
+git format-patch -1
+```
+
+Git will now create a `.patch` file in the current directory.
+
+3. Attach this `.patch` file in an email to me at
+   [jack-benny@cyberinfo.se](mailto:jack-benny@cyberinfo.se).
+   **Leave the filename as it is**. I'll apply the patch and push it to the repository.
+   In your email, please tell me the name of the repository.
+
+4. Once you’ve sent the email, you can delete the patch file from your computer.
+
+## Multiple commits
+If you've made multiple commits to a project that you want to contribute,
+simply change git format-patch -1 to reflect the number of commits.
+
+For example, if you've made four commits, run:
+
+```bash
+git format-patch -4
+```
+
+This will produce four separate `.patch` files. **Email me all of them, with
+their filenames intact**. The filenames tell me the order in which to apply
+them, as well as the commit messages.
+
+Also, please include the repository name in your email.
+
+I'll apply the patches and push them to the repository.
+
+## Good to know
+Your name and email (as configured in your local Git) will appear in the
+commit history.
