In plain English

This is a personal study notebook from a developer named Qin Jianxiang. The repository collects short guides intended to get someone up to speed on a topic in roughly 30 to 60 minutes. The content is written in Chinese, so the audience is readers comfortable with that language. The guides fall into two categories. The first is a hands-on series covering practical skills: there is an entry on getting started with iOS development (described as a 60-minute intro) and another on shell programming (a 30-minute intro). Shell programming refers to writing small scripts that run in a terminal to automate tasks on a computer. The second category covers underlying principles, with one document explaining how a mobile device figures out its physical location, covering the concepts behind GPS and network-based positioning. There is also a separate section for non-technical business notes. One document in that section looks at promotional rules in the retail industry, such as how discount and coupon systems are structured. The README is a simple list of links to these individual documents. It does not include installation instructions, external dependencies, or a license statement. The project appears to be a personal reference collection rather than a library or tool meant for integration into other software. Anyone wanting a fast overview of iOS basics, shell scripting, or related topics in Chinese would find it worth browsing. Developers looking for English-language documentation or executable code would need to look elsewhere.
