I'm also writing stuff on Medium, mine are more about design (User experience & cie), and I'm actually working on a ux design starter guide for Hololens and mixed reality. Since I have started, it has been like 4000 words, so, I decided to split it into multiple parts (4 parts to be precise). And you know what, it has been way more easier for people to read it, since they were not afraid to just lost their way into a one big article and they could just start it one day and read the second part later (6 to 8 minutes reading is what I learned perform the most at keeping the user's attention).
You should probably do the same. It also helps maintaining high motivation for yourself since you can see people reading what you first started to write and adjust thing if it's not clear for the next part.
Share big things as soon as possible to get feedback and don't be afraid to split it into multiple parts to make it more accessible.
Just some advices as I would be very happy to read the thing you're writing.
