Usermanual Space.
The best way to contribute is to:
It can be a bit of work to set up asciidoctor and the plugins to generate the HTML locally but it allows you to make sure your changes look good and any links work properly.
Geopaparazzi's usermanual uses Asciidoc's .adoc format for the source files, but asciidoctor is used to convert the .adoc files to .html (and .pdf?). While you can simply use a text editor to edit the .adoc files, to see the results in html you need to run them through asciidoctor.
I installed and ran asciidoctor on Windows by:
Install Ruby with the RubyInstaller (https://rubyinstaller.org/)
From the Windows Start Menu: Ruby -> "Command prompt with Ruby"
On the command line:
gem install asciidoctor
gem install asciidoctor-diagram
gem install coderay
asciidoctor --version
On the command line, cd to your location of Geopaparazzi's userguide index.adoc and run asciidoctor:
asciidoctor -r asciidoctor-diagram index.adoc
This will create index.html in the same directory.
After reviewing your changes by looking at the HTML, please submit a Pull Request.
Thanks!
