-## Styling and formatting
+See [wiki: Development](https://github.com/nvim-tree/nvim-tree.lua/wiki/Development) for environment setup, tips and tools.
 
-Code is formatted using luacheck, and linted using stylua.
+# Tools
-You can install these with:
 
-```bash
+Following are used during CI and strongly recommended during local development.
-luarocks install luacheck
+
-cargo install stylua
+Language server: [luals](https://luals.github.io)
+
+Lint: [luacheck](https://github.com/lunarmodules/luacheck/)
+
+Style: [EmmyLuaCodeStyle](https://github.com/CppCXY/EmmyLuaCodeStyle): `CodeCheck`
+
+nvim-tree.lua migrated from stylua to EmmyLuaCodeStyle ~2024/10. `vim.lsp.buf.format()` may be used as it is the default formatter for luals
+
+You can install them via you OS package manager e.g. `pacman`, `brew` or other via other package managers such as `cargo` or `luarocks`
+
+# Quality
+
+The following quality checks are mandatory and are performed during CI. They run on the entire `lua` directory and return 1 on any failure.
+
+You can run them all via `make` or `make all`
+
+You can setup git hooks to run all checks by running `scripts/setup-hooks.sh`
+
+## lint
+
+1. Runs luacheck quietly using `.luacheck` settings
+
+```sh
+make lint
 ```
 
-You can setup the git hooks by running `scripts/setup-hooks.sh`.
+## style
 
-## Adding new actions
+1. Runs CodeCheck using `.editorconfig` settings
+1. Runs `scripts/doc-comments.sh` to validate annotated documentation
+
+```sh
+make style
+```
+
+You can automatically fix `CodeCheck` issues via:
+
+```sh
+make style-fix
+```
+
+## check
+
+1. Runs the checks that the LSP lua language server runs inside nvim using `.luarc.json` via `scripts/luals-check.sh`
+
+```sh
+make check
+```
+
+Assumes `$VIMRUNTIME` is `/usr/share/nvim/runtime`. Adjust as necessary e.g.
+
+```sh
+VIMRUNTIME="/my/path/to/runtime" make check
+```
+
+If `lua-language-server` is not available or `--check` doesn't function (e.g. Arch Linux 3.9.1-1) you can manually install it as per `ci.yml` e.g.
+
+```sh
+mkdir luals
+curl -L "https://github.com/LuaLS/lua-language-server/releases/download/3.9.1/lua-language-server-3.9.1-linux-x64.tar.gz" | tar zx --directory luals
+
+PATH="luals/bin:${PATH}" make check
+```
+
+# Adding New Actions
 
 To add a new action, add a file in `actions/name-of-the-action.lua`. You should export a `setup` function if some configuration is needed.
-Once you did, you should run the `scripts/update-help.sh`.
 
-## Documentation
+Once you did, you should run `make help-update`
+
+# Documentation
+
+## Opts
 
 When adding new options, you should declare the defaults in the main `nvim-tree.lua` file.
-Once you did, you should run the `scripts/update-help.sh`.
 
-Documentation for options should also be added, see how this is done after `nvim-tree.disable_netrw` in the `nvim-tree-lua.txt` file.
+Documentation for options should also be added to `nvim-tree-opts` in `doc/nvim-tree-lua.txt`
 
-## Pull Request
+## API
 
-Please reference any issues in the description e.g. "resolves #1234".
+When adding or changing API please update :help nvim-tree-api
+
+# Windows
+
+Please note that nvim-tree team members do not have access to nor expertise with Windows.
+
+You will need to be an active participant during development and raise a PR to resolve any issues that may arise.
+
+Please ensure that windows specific features and fixes are behind the appropriate feature flag, see [wiki: OS Feature Flags](https://github.com/nvim-tree/nvim-tree.lua/wiki/Development#os-feature-flags)
+
+# Pull Request
+
+Please reference any issues in the description e.g. "resolves #1234", which will be closed upon merge.
 
 Please check "allow edits by maintainers" to allow nvim-tree developers to make small changes such as documentation tweaks.
+
+## Subject
+
+The merge commit message will be the subject of the PR.
+
+A [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0) subject will be validated by the Semantic Pull Request Subject CI job. Reference the issue to be used in the release notes e.g.
+
+`fix(#2395): marks.bulk.move defaults to directory at cursor`
+
+Available types:
+* feat: A new feature
+* fix: A bug fix
+* docs: Documentation only changes
+* style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
+* refactor: A code change that neither fixes a bug nor adds a feature
+* perf: A code change that improves performance
+* test: Adding missing tests or correcting existing tests
+* build: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
+* ci: Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
+* chore: Other changes that don't modify src or test files
+* revert: Reverts a previous commit
+
+If in doubt, look at previous commits.
