Generate your documentation from bulky README.md files
Github is full of mid-sized projects that help us solve specific tasks. Authors tend to document these repositories with beautiful README.md files and some auxiliary documents.
mdsplit
is a tool that splits these bulky README.md files into smaller files in a way compatible with GitHub Pages +
GitHub Actions + MkDocs. GitHub Actions will then regenerate the documentation whenever your README.md
file is
updated.
See the mdsplit LIVE DEMO and compare it with this
very README.md
file.
Table of Contents
Go to your repository settings and turn on GitHub Pages on the branch gh-pages.
Copy the mkdocs.yml
file to your repository:
??? info "See contents"
=== "mkdocs.yml"
```yaml hl_lines="1 2 3 4 6 30"
--8<-- "mkdocs.yml"
```
Copy the .github/workflows/docs.yml
file to your repository:
??? info "See contents"
=== "docs.yml"
```yaml hl_lines="21 22 31-44 48"
--8<-- ".github/workflows/docs.yml"
```
In a few seconds, your README.md file will become a beautiful documentation.
After installing mdsplit
, run
mdsplit -r username/repository
from your project root directory to generate your documentation.
mdsplit
will split your README.md
file into smaller files and save the results to the docs
directory.
!!! note This is directory from where mkdocs will later build your documentation.
You might want to test your documentation locally before pushing it to your repository.
Install mkdocs with
pip install mkdocs-material
After generating the docs with mdsplit, run the mkdocs server with
mkdocs serve
Or build the static documentation with
mkdocs serve
Use this mkdocs configuration file to get started:
=== "mkdocs.yml"
--8<-- "mkdocs.yml"
Replace the settings with your repository information.
You can integrate mdsplit
with GitHub actions to regenerate the documentation whenever you change your README.md
file.
Use this workflow to get started:
=== ".github/workflows/docs.yml"
```yaml hl_lines="21 22 31-44 48"
--8<-- ".github/workflows/docs.yml"
```
Replace the settings with your repository information.
Most steps in this workflow are optional:
- The step
technote-space/toc-generator@v2
creates a table of contents for your README.md file - The second step downloads and builds the master version of mdsplit. This is the version we use in this repository, but you probably want to use a more stable version in your own repository. To do that, comment this step and use the third and forth steps instead.
- The third and fourth steps (commented out) download the latest release version of mdsplit. That's probably what you want for your repository. Uncomment these steps to do that.
- The next steps are pushing the docs to your master branch. Make any adjustments you might need.
- The last steps are taking the docs from your master branch and publishing them to your gh-pages branch.

Help options:

-v, --version Print version
The --repository
(or -r
) option should be used to provide your repository name to mdsplit
. This option enables mdsplit
to create links to files inside the repository.
Although all internal repository links work in GitHub, not all internal links are adjusted to work with GitHub Pages. Documentation files can only contain links to other markdown files in the documentation directory.
If your documentation needs to refer to a file in the repository and this file is not under .docs/
, links need to use
the absolute repository link as a parent path.
For instance, consider a file source/main.cpp
outside docs
. Then
[My Internal Link](source/main.cpp)
should become
[My Internal Link](https://github.com/my_username/my_repository/blob/master/source/main.cpp)
so that the link works correctly on GitHub pages.
You can use the --repository
(or -r
) option to provide the repository mdsplit
should consider to generate these
links:
mdsplit -r alandefreitas/matplotplusplus
Use the comments <!-- START mdsplit-ignore -->
and <!-- END mdsplit-ignore -->
to ignore sections from
your README.md
. For instance:
=== "Markdown"
```md
<!-- START mdsplit-ignore -->
# Section to ignore
`mdsplit` will remove this whole section from your documentation.
<!-- END mdsplit-ignore -->
```
or
=== "Markdown"
```md
# Section to ignore
<!-- START mdsplit-ignore -->
`mdsplit` will remove this paragraph from your documentation.
<!-- END mdsplit-ignore -->
```
If you ignore the complete section, mdsplit
will create no file for that section.
If you're reading this from README.md
you will see this section has a subsection that will be completely
ignored in the documentation.
This section will be completely ignored by the documentation. Have a look at the Section Hiding sections from docs in the documentation.
The --input
(or -i
) option defines the file mdsplit
should split to generate the documentation. You don't usually
want to change the default from README.md
because that's the file GitHub uses for all repositories.
However, it might be useful to use another file as input if you want to have your documentation in a bulky markdown file
kept separate from your main README.md
.
The --output
(or -o
) option defines the directory where mdsplit
should store the documentation. You don't usually want to change the default from docs
because GitHub Pages gives you only two options for the documentation directory:
And cluttering the root directory with lots of markdown files and directories is not a good idea unless you are going to create another branch for your documentation.
The --clear-html
(or -d
) option defines the HTML tags mdsplit
should remove from your README.md
. This is useful
to README.md
files that use tags such as details
and summary
to emulate what the documentation would look like
inside the README.md
file.
By default, mdsplit
will remove the tags details
and summary
because 1) Jekyll themes often have difficulty with
these tags and 2) people often use these tags in markdown files to emulate what the documentation would look like.
The --front-matter
(or -f
) option tells mdsplit
to generate a front matter for each new file. The default option
is true
so you need --front-matter=false
to turn it off.
This front matter includes parameters such as title
, nav_order
, parent
, has_children
, and nav_exclude
for each
markdown file.
Jekyll themes can use these parameters to generate proper navigation bars, order pages, and define page titles.
In principle, mdsplit
will not remove any files in your documentation directory. It will only create or update files.
This is meant to allow auxiliary files that you also want to be part of the documentation.
However, that also means that if you change your section names in README.md
, mdsplit
will create a new file for this
section and the old file would be left untouched. Your GitHub pages would then show you the new and old sections.
If this is not an auxiliary file you want in your documentation, you need to remove these files.
To make it easier to identify external auxiliary files, after saving the new markdown files, mdsplit
will look for
any .md
files in the docs
directory. If there are any files not generated by mdsplit
, it will emit a message like
the following:
=== "Output"
```console
# The following .md files were not generated by mdsplit
# Please make sure that is on purpose:
Outsider doc file: docs/README.md
Outsider doc file: docs/COMPLETE_GALLERY.md
```
If any of these files contain a comment indicating that mdsplit
generated the file, then mdsplit
might automatically
remove the file. You can control this behaviour with the --erase-old-mdsplit-files
(or -e
) option. The default value
is true
so you need --erase-old-mdsplit-files=false
to turn it off.
