Contributing docs for v1

v1 docs are under docs/v1. Currently, most articles are symlinked to the corresponding file in docs/.

  • If you are updating an exiting article. Just replace the symlink with an actual article.
  • If you are adding a new article, just add it under docs/v1.

Once v1 is released, this process will be updated.

INCLUDE pragma

You can use the "INCLUDE pragma" to avoid copy-and-pasting the same content or updates on multiple pages.

The syntax is as follows:

INCLUDE: <filename without extension>

... the rest of the document.

Please remember to include a blank line between "INCLUDE..." and the rest of the document. The docs app will search for <filename>.txt in the docs directory and insert its contents into the current document.

For example, if you write

INCLUDE: _buffer_parameters

... the rest of the document.

then the docs app will insert the contents of _buffer_parameters.txt into the current document.
