# Theme Development
If you have knowledge in web development and want to make deeper changes in the theme or if you want to create a theme based on Firma you can follow this guide to learn how to setup a development environment easily.
# Development Mode
The following steps will guide you so that you can have a development environment on your machine without having to install Ghost locally:
Make a backup of the theme folder, just in case.
Open a terminal and change to the
npm run get-databaseto get the Ghost database dump.
npm run docker-watch.
If all goes well, a tab will open in your browser with this URL:
To access the Ghost Admin just enter this URL in your browser:
http://localhost:3000/ghost. The credentials are:
Email address: firstname.lastname@example.org Password: 0123456789
You might need to run
docker-compose restart after adding new files, this is because (from Ghost documentation):
If you add any new files to your theme during development, you'll need to restart Ghost to see the changes take effect.
Please ignore the following error if it appears after running
fatal: not a git repository (or any of the parent directories): .git husky > Failed to install
If after a few seconds the page does not load, please wait a little longer or refresh the page several times, it will load 😉
# Production Mode
When you are done making all your changes you can run
npm run production ( within the
src directory) to build your theme in production mode.
npm run production will concatenate, minify, optimize and compress all your files and finally will generate the file
firma.zip in the root of the theme folder.
Now you can upload this file in the Ghost Admin and you're ready to go!
