+# Turn the speed blue
+*A getting started guide for openpilot development*
+
+In 30 minutes, we'll get an openpilot development environment setup on your computer and make some changes to openpilot's UI.
+
+And if you have a comma 3/3X, we'll deploy the change to your device for testing.
+
+## 1. Setup your development environment
+
+Run this to clone openpilot and install all the dependencies:
+```bash
+curl -fsSL openpilot.comma.ai | bash
+```
+
+Then, compile openpilot:
+```bash
+cd openpilot
+scons -j8
+```
+
+## 2. Run replay
+
+We'll run the `replay` tool with the demo route to get data streaming for testing our UI changes.
+```bash
+# in terminal 1
+tools/replay/replay --demo
+
+# in terminal 2
+selfdrive/ui/ui
+```
+
+The openpilot UI should launch and show a replay of the demo route.
+
+If you have your own comma device, you can replace `--demo` with one of your own routes from comma connect.
+
+## 3. Make the speed blue
+
+Search for “mph” with git grep in the `ui` folder.
+```bash
+$ git grep "mph" selfdrive/ui/
+paint.cc:  ui_draw_text(s, s->fb_w/2, 290, s->scene.is_metric ? "km/h" : "mph", 36 * 2.5, COLOR_WHITE_ALPHA(200), "sans-regular");
+```
+
+The line right above contains the actual speed. Unfortunately, COLOR_BLUE isn’t defined, but a git grep of COLOR_WHITE shows it’s nvgRGBA(255, 255, 255, 255). Personally, I like a lighter blue, so I went with #8080FF.

+
+## 5. Push your fork to GitHub
+
+Click fork on GitHub. Then, push with:
+```bash
+git remote rm origin
+git remote add origin git@github.com:<your-github-username>/openpilot.git
+git add .
+git commit -m "Make the speed blue."
+git push --set-upstream origin master
+```
+
+### 6. Run your fork on device in your car!
+
+Uninstall openpilot from your device through the settings. Then, enter the URL for your very own installer:
+```
+installer.comma.ai/<your-github-username>/master
+```
+
+### 7. Admire your work IRL
