Your English is great. I'm a native speaker, and reading your post, I thought you were too. A slightly sloppy one with a couple odd turns of phrase, but perfectly clear and comprehensible. I understood the quoted parts just fine.

That said, please don't make excuses about how little time you spent on it. It might be true, but it shows lack of respect for your audience. Like code, if it's worth writing at all, it's probably worth writing well.

Keep writing, keep coding!
