Nice write up! Thank you for sharing.
You can try making your "table of content" linkable, so when people click on it, they're brought to that particular section. i.e.
some content... some content... some content... some content...
another content... another content... another content... another content...
more content... more content...
Here's how it looks in markdown
# content
- [I want to be a developer](#I-want-to-be-a-developer)
- [Community](#community)
- [Technology tree](#technology-tree)
# I want to be a developer
some content....
some content....
some content....
some content....
# Community
another content...
another content...
another content...
another content...
# Technology
more content...
more content...
I hope this helps.
