microsoft/pxt: README-based editorial guide

microsoft/pxt describes itself in the README as "Microsoft MakeCode (PXT - Programming eXperience Toolkit)". This article keeps to facts that can be checked in the repository. Stars, forks, and promotional badges are signals of attention, not proof of quality. Under "Microsoft MakeCode", the README says: Microsoft MakeCode is based on the open source project Microsoft Programming Experience Toolkit (PXT). Microsoft MakeCode is the name in the user-facing editors, PXT is used in all the GitHub sources.. That establishes the project's stated boundary, not a production test.

The README's "Microsoft MakeCode" section gives a useful starting point for deciding whether the project fits: extensibility support to define new blocks in TypeScript. If that problem is not yours, popularity is a poor reason to adopt it. Project names, commands, and component names are kept as written so a reader can return to the primary source without guessing at terminology. Another checkable README item is: a Blockly-based code editor along with converter to the text format. It can shape a first test, but it does not replace testing in the intended environment.

The operating model is spread across sections such as "Linking a target to PXT". The source evidence includes: If you are modifying your own instance of PXT and want a target (such as pxt-microbit) to use your local version, cd to the directory of the target (pxt-microbit, in our example, which should be a directory sibling of pxt) and perform. This article does not turn missing architecture, performance, or security details into claims. A real deployment still needs a look at the repository layout, configuration files, and release history.

Start installation from the README's documented entry point. A command that can be checked in the source is: npm install npm run build When the README contains no runnable command, this article does not invent one. Open its "Branches" section and confirm system dependencies, default ports, and first-run initialization before using a public server.
