Deployment
Create GitHub repositoryPublish with GitHub Pages
The site is already arranged in the repository’s /docs directory and includes an optional Actions workflow.
Push the repository
git init
git add .
git commit -m "Launch OpenSat Mission Lab web edition"
git branch -M main
git remote add origin YOUR_REPOSITORY_URL
git push -u origin mainEnable Pages
Open Settings → Pages. Under “Build and deployment,” select Deploy from a branch, choose main, and select the /docs folder.
Sourcemain /docs
Open the live site
Your public address will use this structure:
https://YOUR_USERNAME.github.io/YOUR_REPOSITORY/Every module works without a Python server.
Optional Actions deployment
The included .github/workflows/pages.yml validates and deploys the static site whenever main changes.
git add .github/workflows/pages.yml
git commit -m "Enable Pages deployment"
