documentation: add anchors to MyFirstContribution

nasamuffin · gitster · commit 5ef811ac5d60 · 2019-05-19T11:01:24.000+09:00
During the course of review for MyFirstContribution.txt, the suggestion came up to include anchors to make it easier for veteran contributors to link specific sections of this documents to newbies. To make life easier for reviewers, add these anchors in their own commit. See review context here: https://public-inbox.org/git/20190507195938.GD220818@google.com/ AsciiDoc does not support :sectanchors: and the anchors are not discoverable, but they are referenceable. So a link to "foo.com/MyFirstContribution.html#prerequisites" will still work if that file was generated with AsciiDoc. The inclusion of :sectanchors: does not create warnings or errors while compiling directly with `asciidoc -b html5 Documentation/MyFirstContribution.txt` or while compiling with `make doc`. AsciiDoctor does support :sectanchors: and displays a paragraph link on mouseover. When the anchor is included above or inline with a section (as in this change), the link provided points to the custom ID contained within [[]] instead of to an autogenerated ID. Practically speaking, this means we have .../MyFirstContribution.html#summary instead of .../MyFirstContribution.html#_summary. In addition to being prettier, the custom IDs also enable anchor linking to work with asciidoc-generated pages. This change compiles with no warnings using `asciidoctor -b html5 Documentation/MyFirstContribution.txt`.
