 3. Select the GitHub repo that contains your Zola website and connect it to Cloudflare Pages
 4. Click _"Begin setup"_
 5. Enter your project name. Keep in mind that if you would like to use the default Pages domain (pages.dev), this will be your website's future URL ("yourprojectname.pages.dev"). Additionally, select a production branch.

+## Troubleshooting
+
+Some tips to help troubleshoot issues getting started with Cloudflare Pages.
+
+### `zola: not found`
+
+If you see build output that resembles something like this:
+
+```sh
+23:03:54.609	> build
+23:03:54.609	> zola build $BUILD_OPTS && npx tailwindcss -i ./public/input.css -o ./public/style.css -m
+23:03:54.609
+23:03:54.621	sh: 1: zola: not found
+23:03:54.635	Failed: Error while executing user command. Exited with error code: 127
+23:03:54.644	Failed: build command exited with code: 1
+23:03:55.699	Failed: error occurred while running build command
+```
+
+Then it might be due to an [outstanding issue](https://github.com/cloudflare/pages-build-image/issues/3#issuecomment-1646873666). There are currently two recommended workarounds:
+
+#### Change the **build system version** to `v1`
+
+From within the workers & pages dash, go to the following:
+<Your Project> Settings > Builds & deployments > Build system version > Configure build system
+
+Then select `v1` and save.
+
+#### Or use `UNSTABLE_PRE_BUILD` environment variable + `asdf`
+
+From within the workers & pages dash, do the following:
+<Your Project> Settings > Environment variables > Edit variables
+
+And add an environment variable `UNSTABLE_PRE_BUILD`, with the following value and save.
+
+```sh
+asdf plugin add zola https://github.com/salasrod/asdf-zola && asdf install zola 0.17.2 && asdf global zola 0.17.2
+```
