-## Styling and formatting
+# Tools
 
-Code is formatted using luacheck, and linted using stylua.
-You can install these with:
+Following are used during CI and strongly recommended during local development.
 
-```bash
-luarocks install luacheck
-cargo install stylua
+Lint: [luacheck](https://github.com/lunarmodules/luacheck/)
+
+Style: [StyLua](https://github.com/JohnnyMorganz/StyLua)
+
+Language server: [luals](https://luals.github.io)
+
+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 stylua using `.stylua.toml` settings
+1. Runs `scripts/doc-comments.sh` to validate annotated documentation
+
+```sh
+make style
+```
+
+You can automatically fix stylua 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
+```
+
+# 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
 
 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 to `nvim-tree-opts` in `doc/nvim-tree-lua.txt`

+ 8.1 HIGHLIGHT OVERHAUL                         *nvim-tree-highlight-overhaul*
+
+2024-01-20: significant highlighting changes, some breaking:
+
+- Full cterm support.
+- Standard vim highlight groups such |DiagnosticUnderlineError| are now the
+  defaults.
+- Highlight groups named consistently.
+- All `highlight_xxx` e.g. |nvim-tree.renderer.highlight_git| are granular,
+  allowing  `"none"`, `"icon"`, `"name"` or `"all"`
+- `highlight_xxx` has highlight groups for both File and Folder
+- `highlight_xxx` is additive instead of overwriting. See
+  |nvim-tree-opts-renderer| for precedence.
+
+2024-01-29: disambiguate default highlights sharing groups:
+
+- NvimTreeRootFolder   PreProc   -> Title
+- NvimTreeModified*    Constant  -> Type
+- NvimTreeOpenedHL     Constant  -> Special
+- NvimTreeBookmarkIcon Constant  -> NvimTreeFolderIcon
+- NvimTreeExecFile     Constant  -> SpellCap
+- NvimTreeImageFile    PreProc   -> SpellCap
+- NvimTreeSpecialFile  PreProc   -> SpellCap
+- NvimTreeSymlink      Statement -> SpellCap
+
+Legacy highlight group are still obeyed when they are defined and the current
+highlight group is not, hard linking as follows: >
+
+    NvimTreeModifiedIcon        NvimTreeModifiedFile
