Setting Up Your Hugo Project

If you don’t already have a Hugo project, let’s create one!

1. Start a Hugo project in a directory called app:

   hugo new site app

1. Move into your new project:

   cd app

Installing the Theme

You can add a Hugo theme in two main ways: using a Git submodule or downloading it manually.

Method 1: Git Submodule (Best for Easy Updates)

1. Add the theme to your Hugo project:

   git submodule add https://github.com/theme-author/theme-repo.git themes/theme-folder

1. Open config.toml (or config.yaml) and set your theme:

   theme = "theme-folder"

Method 2: Manual Download

1. Download the theme from its GitHub repository and unzip it.
2. Place the unzipped folder into app/themes/, naming it theme-folder.
3. Update config.toml:

   theme = "theme-folder"

Using an Alternative Project Directory

If your Hugo project is located in a different directory (e.g., ./app/hugo-site), you’ll just need to adjust paths:

1. Move to the project root:

   cd ./app/hugo-site

1. Install the theme as described above in ./app/hugo-site/themes/theme-folder.

2. In config.toml, set the theme:
   

   theme = "theme-folder"

1. Run Hugo from this directory to view your site:

   hugo server -D

How Themes Work in Hugo (Quick Overview)

Themes in Hugo bundle templates, layouts, and assets, giving your site a professional look with minimal setup. When Hugo builds your site, it merges the theme files with your content files to create the final website.

Updating the Theme

If you installed the theme as a Git submodule, updating is straightforward:

1. Navigate to the theme folder:

   cd app/themes/theme-folder

1. Pull the latest updates:

   git pull origin main

1. Return to your project directory:
   

   cd ../..
   

2. Commit the update:
   

   git add themes/theme-folder
   git commit -m "Update theme to latest version"

For manual installs, just replace the old theme folder with a fresh download.

Running Your Site Locally

Once the theme is installed, run your site locally to preview it:

hugo server -D

Check out http://localhost:1313 in your browser to see the theme in action.
