Escada de madeira para jardim com R$ 40 / Wooden stair for a garden (w/ subtitles)

I'll show you how I made a custom staircase to provide access to an unused area at the back of a property. The cost of the wood (eucalyptus planks, plus planed pine strips) was R$ 31 (in June 2020). Another R$ 8 was spent on screws. The entire job took 5 hours, not counting the time spent applying marine varnish. I used the tools I had, not necessarily the most suitable for each step of the process. This is the first time I've made this type of staircase, and the goal of posting this is to show the step-by-step process and learn. Perhaps even get tips from more experienced people. This is how I made a customized staircase and placed it over a wall to give access to an unused area in the backyard. The entire work took me five hours because I used the tools I have, not necessarily the best fit for each case. It's my first time doing this kind of project, and my goal is to show you all the process and the learning experience along the way. If I can get some pro tips, even better.
