Enable documentation for your Component

By default, the Docs tab in your catalog does not include documentation for a new software component. However, you can quickly publish Markdown documentation to the Docs tab.


Docs in Harness IDP is powered by TechDocs Backstage Plugin and which currently is using MkDocs to generate the documentation from source, so the files have to be in Markdown format with a mkdocs.yml file present in the path provided.

To add documentation:

  1. Create a docs directory next to where you have catalog-info.yaml.
  2. Inside the docs directory, create an file with the following contents.
# Welcome!

This is a basic example of documentation. It is intended to showcase some of the
features that TechDocs provides out of the box.

## Basic Markdown


# h1

## h2

### h3

#### h4

##### h5

###### h6

Here is a bulleted list:

- Item one
- Item two
- Item Three

Check out the [Markdown Guide]( to learn more about how to
simply create documentation.

## Table example

While this documentation isn't comprehensive, in the future it should cover the following
topics outlined in this example table:

| Topic | Description |
| ------- | ------------------------------------------------------------ |
| Topic 1 | An introductory topic to help you learn about the component. |
| Topic 2 | A more detailed topic that explains more information. |
| Topic 3 | A final topic that provides conclusions and lessons learned. |

## Learn more about MkDocs

TechDocs uses MkDocs as the static site generator. Visit for more information about MkDocs.
  1. Edit the catalog-info.yaml and add the TechDocs annotation.

  2. In the metadata.annotations field, add dir:..

When you seedir:., you can translate it to mean:

  • That the documentation source code lives in the same location as the catalog-info.yaml file.
  • That, in particular, the mkdocs.yml file is a sibling of catalog-info.yaml (meaning, it is in the same directory)
  • And that all of the source content of the documentation would be available if one were to download the directory containing those two files (as well as all sub-directories).

The directory tree of the entity would look something like this:

├── catalog-info.yaml
├── mkdocs.yml
└── docs

If, for example, you wanted to keep a lean root directory, you could place your mkdocs.yml file in a subdirectory and update the annotation value accordingly, e.g. to dir:./sub-folder:

├── catalog-info.yaml
└── sub-folder
├── mkdocs.yml
└── docs

Please note dir:../. does not work in the above use case due to security reasons.

  1. Select the refresh button on the catalog component page.

  1. Navigate to the Docs tab to review the documentation, which should become available shortly.
