+# How to set up a GitHub instance of the QMK Configurator
+
+This document will walk you through deploying an instance of the QMK Configurator via your own repository.
+
+## 1. Fork the qmk/qmk_configurator repository
+
+Go to [qmk/qmk_configurator](https://github.com/qmk/qmk_configurator), and click the `fork` button at top right.
+
+## 2. Create a gh-pages branch
+
+In your git CLI, enter:
+
+    git checkout gh-pages
+
+This will create a copy of the `gh-pages` branch that is already on the QMK repo.
+
+## 3. Remove the CNAME file
+
+Remove the `CNAME` file, which is only for the production version of the Configurator.
+
+    rm CNAME
+
+## 4. Edit the _config.yml file
+
+In the root directory, open the `_config.yml` file in a text editor, and edit it as appropriate:
+
+    title: QMK Configurator
+    email: <github_email>     # the email attached to your GitHub account
+    show_downloads: true
+    description: QMK for potatoes - an open source configurator for QMK Firmware (only the AVR boards right now)
+    baseurl: "/qmk_configurator"     # DO NOT CHANGE THIS LINE!
+    # Replace <github_username> on the following three lines with your GitHub username
+    url: "http://<github_username>.github.io"
+    github_username: <github_username>
+    repository: <github_username>/qmk_configurator
+    theme: jekyll-theme-minimal
+
+## 5. Deploy your instance
+
+When you're done editing, save the file, commit it to your branch, and push your changes to your GitHub repo.
+
+    git add .
+    git commit -m "initial setup"
+    git push
+
+Once you've pushed your changes, your instance should be live in about 30 seconds at `https://<github_username>.github.io/qmk_configurator`.
