 - It is more secure because scripts loaded for all extensions are generated by vim-polyglot (ftdetect).
 - Solid syntax and indentation support (other features skipped). Only the best language packs.
 - All unnecessary files are ignored (like enormous documentation from php support).
-- No support for esoteric languages, only most popular ones (modern too, like `slim`).
+- Automatically detect indentation (includes performance-optimized version of [vim-sleuth](https://github.com/tpope/vim-sleuth))
 - Each build is tested by automated vimrunner script on CI. See `spec` directory.

 ## Contributing
 
 Language packs are periodically updated using automated `scripts/build` script.
 
-Feel free to add your language to `packages.yaml`, and send pull-request. Please don't run `make` and include that in your PR, send just changes to `packages.yaml` and build scripts if really necessary. You can run `make test` to run rough tests.
+Feel free to add your language to `packages.yaml` + `heuristics.yaml`, and send pull-request. You can run `make test` to run rough tests. And `make dev` for easy development.
