-The source of truth is `Zig.YAML-tmLanguage`. This file is read by linguist

 TextMate Installation
 ---------------------
 
-This language is also compatible with TextMate's `.tmBundle` format. To install in TextMate clone or download this repository. Then rename the repository directory to `Zig.tmBundle` and double-click it to install it into TextMate. However, see [Zig.tmbundle](https://github.com/ziglang/Zig.tmbundle) for dedicated TextMate support.

 Local Development
 -----------------
 
-Install https://github.com/SublimeText/PackageDev.
-
 Clone or copy this repository to your local Sublime Text folder. e.g.
 
 ```
 git clone https://github.com/ziglang/sublime-zig-language.git "/Users/$USER/Library/Application Support/Sublime Text 3/Packages/Zig Language"
 ```
 
-Edit the YAML entry and use the `Convert (YAML, JSON, PList) to...` command
-to generate the other entries. Sublime Text will automatically reload the plugin, showing changes in the build system, syntax highlighting, etc.
+For working on ST3+ support, you can edit the `.sublime-syntax` directly.
+But installing [PackageDev](https://packagecontrol.io/packages/PackageDev)
+will provide some syntax highlighting.
+You can run the tests in [syntax_test.zig](./Syntaxes/syntax_test.zig)
+with the "Syntax Tests" builtin build system.
+Sublime Text will automatically reload the syntax on save.
+If you have a big Zig project open this can make your CPU spin while Sublime reindex everything.

+For working on the old `.tmLanguage` syntax, work on the `Zig.YAML-tmLanguage` file.
+**Important** Github Linguist's source of truth is `Zig.YAML-tmLanguage`.
+Work on `Zig.YAML-tmLanguage` the use PackageDev command: `Convert (YAML, JSON, PList) to...`

+Sublime Text should also automatically reload the plugin, but doesn't have unit tests for `tmLanguage`.
