This section will guide you through:
- Create a basic documentation setup
- Writing and previewing your documentation
- A working Backstage instance with TechDocs installed (see TechDocs getting started)
Create a basic documentation setup
If you have an existing repository that you'd like to add documentation to, skip to the Manually add documentation setup section below. Otherwise, continue reading to start a documentation repo from scratch.
Use the documentation template
Your working Backstage instance should by default have a documentation template added. If not, copy the catalog locations from the create-app template to add the documentation template. The template creates a component with only TechDocs configuration and default markdown files as below mentioned in manual documentation setup, and is otherwise empty.
Create an entity from the documentation template and you will get the needed setup for free.
Manually add documentation setup to already existing repository
- An existing component
registered in backstage
(e.g. via a
mkdocs.yml file in the root of your repository with the following
site_name: 'example-docs' nav: - Home: index.md plugins: - techdocs-core
Update your component's entity description by adding the following lines to its
catalog-info.yaml in the root of its repository:
metadata: annotations: backstage.io/techdocs-ref: dir:.
is used by TechDocs to download the documentation source files for generating an
Entity's TechDocs site.
/docs folder in the root of the project with at least an
file. (If you add more markdown files, make sure to update the nav in the
mkdocs.yml file to get a proper navigation for your documentation.)
Note - Although
docsis a popular directory name for storing documentation, it can be renamed to something else and can be configured by
mkdocs.yml. See https://www.mkdocs.org/user-guide/configuration/#docs_dir
docs/index.md can for example have the following content:
# example docs This is a basic example of documentation.
Commit your changes, open a pull request and merge. You will now get your updated documentation next time you run Backstage!
Writing and previewing your documentation
techdocs-cli you can preview your docs inside a local Backstage
instance and get live reload on changes. This is useful when you want to preview
your documentation while writing.
To do this you can run:
cd /path/to/docs-repository/ npx @techdocs/cli serve
