Testing Installation with Hugo Help
Once you have installed Hugo, make sure it is in your PATH. You can test that Hugo has been installed correctly via the help command:
hugo help
The output you see in your console should be similar to the following:

Additional help topics:
hugo check Contains some verification checks
Use "hugo [command] --help" for more information about a command.
The most common use is probably to run hugo with your current directory being the input directory:
hugo
0 draft content
0 future content
99 pages created
0 paginator pages created
16 tags created
0 groups created
in 120 ms
This generates your website to the public/ directory, ready to be deployed to your web server.
Instant feedback as you develop your web site
If you are working on things and want to see the changes immediately, by default Hugo will watch the filesystem for changes and rebuild your site as soon as a file is saved:
hugo -s ~/Code/hugo/docs
0 draft content
0 future content
99 pages created
0 paginator pages created
16 tags created
0 groups created
in 120 ms
Watching for changes in /Users/spf13/Code/hugo/docs/content
Press Ctrl+C to stop
Hugo can even run a server and create a site preview at the same time! Hugo implements LiveReload technology to automatically reload any open pages in all JavaScript-enabled browsers, including mobile. This is the easiest and most common way to develop a Hugo web site:
hugo server -ws ~/Code/hugo/docs
0 draft content
0 future content
99 pages created
0 paginator pages created
16 tags created
0 groups created
in 120 ms
Watching for changes in /Users/spf13/Code/hugo/docs/content
Serving pages from /Users/spf13/Code/hugo/docs/public
Web Server is available at http://localhost:1313/
Press Ctrl+C to stop
Hugo may not be the first static site generator to utilize LiveReload technology, but it’s the first to do it right.
The combination of Hugo’s insane build speed and LiveReload make crafting your content pure joy. Your updated content appears virtually instantly in your browser as soon as you save your changes.
LiveReload
Hugo comes with LiveReload built in. There are no additional packages to install. A common way to use Hugo while developing a site is to have Hugo run a server and watch for changes:
hugo server
This will run a fully functioning web server while simultaneously watching your file system for additions, deletions, or changes within the following the following areas of your project organization
/static/*/content/*/data/*/layouts/*/themes/<only your current theme>/*config
Whenever you make changes, Hugo will simultaneously rebuild the site and continue to serve content. As soon as the build is finished, LiveReload tells the browser to silently reload the page.
Most Hugo builds are so fast that you may not notice the change unless looking directly at the site in your browser. This means that keeping the site open on a second monitor (or another half of your current monitor) allows you to see the most up-to-date version of your website without the need to leave your text editor.
{{% note "Closing </body> Tag"%}}
You must have a closing </body> tag for LiveReload to work.
Hugo injects the LiveReload <script> before this tag.
{{% /note %}}
Disabling LiveReload's Watch Feature
LiveReload works by injecting JavaScript into the pages Hugo generates. The script creates a connection from the browser's web socket client to the Hugo web socket server.
LiveReload is awesome for development. However, some Hugo users may use hugo server in production to instantly display updated content. As such, we’ve provided multiple methods made it easy to disable the LiveReload functionality:
hugo server --watch=false
Or...
hugo server --disableLiveReload
The latter flag can be omitted by adding the following key-value to your config file:
disableLiveReload = true
disableLiveReload: true
Deploying Your Website
After running hugo server for local web development, you need to do a final hugo run without the server part of the command to rebuild your site. You may then deploy your site by copying the public/ directory (by FTP, SFTP, WebDAV, Rsync, git push, etc.) to your production web server.
Since Hugo generates a static website, your site can be hosted anywhere, including Heroku, GoDaddy, DreamHost, GitHub Pages, Amazon S3 with CloudFront, Firebase Hosting, or any other cheap (or even free) static web hosting service.
Apache, nginx, IIS...any web server software will work.
{{% warning "Generated Files are NOT Removed on Site Build" %}}
Running hugo does not remove generated files before building. This means that you should delete your public/ directory (or the directory you specified with -d/--destination) before running the hugo command, or you run the risk of the wrong files (e.g., drafts or future posts) being left in the generated site.
{{% /warning %}}
Destination Directories for Dev vs Deploy
Hugo does not remove generated files before building. An easy workaround is to use different directories for development and production.
To start a server that builds draft content (helpful for editing), you can specify a different destination; e.g., a dev/ directory:
hugo server -wDs ~/Code/hugo/docs -d dev
When the content is ready for publishing, use the default public/ dir:
hugo -s ~/Code/hugo/docs
This prevents content you're not yet ready to share from accidentally becoming available.
Using Hugo's Server in Production
Because Hugo is so blazingly fast both in website creation and in web serving (thanks to its concurrent, multi-threaded design and Golang heritage), some users prefer to use Hugo itself to serve their website on their production server.
No other web server software (e.g., Apache, nginx, IIS) is necessary.
Here is the command:
{{% code file="hugo-production-server.sh" %}}
hugo server --baseURL=http://yoursite.org/ \
--port=80 \
--appendPort=false \
--bind=87.245.198.50
{{% /code %}}
Note the bind option, which is the interface to which the server will bind (defaults to 127.0.0.1: fine for most development use cases). Some hosts, such as Amazon Web Services, run NAT (network address translation); sometimes it can be hard to figure out the actual IP address. Using --bind=0.0.0.0 will bind to all interfaces.
By using Hugo's server in production, you are able to deploy just the source files. Hugo, running on your server, will generate the resulting website on the fly and serve them at the same time.
