 # Contributing
 
-Contributors are very welcome! **No contribution is too small and all contributions are valued.**
-
-Some suggestions to get started:
-
-- You can look at the [good first issue](https://github.com/helix-editor/helix/issues?q=is%3Aopen+label%3AE-easy+label%3AE-good-first-issue) label on the issue tracker.
-- Help with packaging on various distributions needed!
-- To use print debugging to the [Helix log file](https://github.com/helix-editor/helix/wiki/FAQ#access-the-log-file), you must:
-  * Print using `log::info!`, `warn!`, or `error!`. (`log::info!("helix!")`)
-  * Pass the appropriate verbosity level option for the desired log level. (`hx -v <file>` for info, more `v`s for higher severity inclusive)
-- If your preferred language is missing, integrating a tree-sitter grammar for
-    it and defining syntax highlight queries for it is straight forward and
-    doesn't require much knowledge of the internals.
-
-We provide an [architecture.md](./docs/architecture.md) that should give you
-a good overview of the internals.
+Contributing guidelines can be found [here](./docs/CONTRIBUTING.md).

 ## Queries
 
-For a language to have syntax-highlighting and indentation among other things, you have to add queries. Add a directory for your language with the path `runtime/queries/<name>/`. The tree-sitter [website](https://tree-sitter.github.io/tree-sitter/syntax-highlighting#queries) gives more info on how to write queries.

+> NOTE: When evaluating queries, the first matching query takes
+precedence, which is different from other editors like neovim where
+the last matching query supercedes the ones before it. See

+# Contributing
+
+Contributors are very welcome! **No contribution is too small and all contributions are valued.**
+
+Some suggestions to get started:
+
+- You can look at the [good first issue][good-first-issue] label on the issue tracker.
+- Help with packaging on various distributions needed!
+- To use print debugging to the [Helix log file][log-file], you must:
+  * Print using `log::info!`, `warn!`, or `error!`. (`log::info!("helix!")`)
+  * Pass the appropriate verbosity level option for the desired log level. (`hx -v <file>` for info, more `v`s for higher severity inclusive)
+- If your preferred language is missing, integrating a tree-sitter grammar for
+    it and defining syntax highlight queries for it is straight forward and
+    doesn't require much knowledge of the internals.
+
+We provide an [architecture.md][architecture.md] that should give you
+a good overview of the internals.
+
+# Auto generated documentation
+
+Some parts of [the book][docs] are autogenerated from the code itself,
+like the list of `:commands` and supported languages. To generate these
+files, run
+
+```shell
+cargo xtask docgen
+```
+
+inside the project. We use [xtask][xtask] as an ad-hoc task runner and
+thus do not require any dependencies other than `cargo` (You don't have
+to `cargo install` anything either).

+helix-syntax
+============
+
+Syntax highlighting for helix, (shallow) submodules resides here.
+
+Differences from nvim-treesitter
+--------------------------------
+
+As the syntax are commonly ported from
+<https://github.com/nvim-treesitter/nvim-treesitter>.
+
+Note that we do not support the custom `#any-of` predicate which is
+supported by neovim so one needs to change it to `#match` with regex.

This is one of the more powerful methods in the standard\nlibrary, used in a variety of contexts.\n\nThe most basic pattern in which `collect()` is used is to turn one\ncollection into another. You take a collection, call [`iter`](https://doc.rust-lang.org/nightly/core/iter/traits/iterator/trait.Iterator.html) on it,\ndo a bunch of transformations, and then `collect()` at the end.\n\n`collect()` can also create instances of types that are not typical\ncollections. For example, a [`String`](https://doc.rust-lang.org/nightly/core/iter/std/string/struct.String.html) can be built from [`char`](type@char)s,\nand an iterator of [`Result<T, E>`](https://doc.rust-lang.org/nightly/core/result/enum.Result.html) items can be collected\ninto `Result<Collection<T>, E>`. See the examples below for more.\n\nBecause `collect()` is so general, it can cause problems with type\ninference. As such, `collect()` is one of the few times you'll see\nthe syntax affectionately known as the 'turbofish': `::<>`. This\nhelps the inference algorithm understand specifically which collection\nyou're trying to collect into.\n\n# Examples\n\nBasic usage:\n\n```rust\nlet a = [1, 2, 3];\n\nlet doubled: Vec<i32> = a.iter()\n                         .map(|&x| x * 2)\n                         .collect();\n\nassert_eq!(vec![2, 4, 6], doubled);\n```\n\nNote that we needed the `: Vec<i32>` on the left-hand side. This is because\nwe could collect into, for example, a [`VecDeque<T>`](https://doc.rust-lang.org/nightly/core/iter/std/collections/struct.VecDeque.html) instead:\n\n```rust\nuse std::collections::VecDeque;\n\nlet a = [1, 2, 3];\n\nlet doubled: VecDeque<i32> = a.iter().map(|&x| x * 2).collect();\n\nassert_eq!(2, doubled[0]);\nassert_eq!(4, doubled[1]);\nassert_eq!(6, doubled[2]);\n```\n\nUsing the 'turbofish' instead of annotating `doubled`:\n\n```rust\nlet a = [1, 2, 3];\n\nlet doubled = a.iter().map(|x| x * 2).collect::<Vec<i32>>();\n\nassert_eq!(vec![2, 4, 6], doubled);\n```\n\nBecause `collect()` only cares about what you're collecting into, you can\nstill use a partial type hint, `_`, with the turbofish:\n\n```rust\nlet a = [1, 2, 3];\n\nlet doubled = a.iter().map(|x| x * 2).collect::<Vec<_>>();\n\nassert_eq!(vec![2, 4, 6], doubled);\n```\n\nUsing `collect()` to make a [`String`](https://doc.rust-lang.org/nightly/core/iter/std/string/struct.String.html):\n\n```rust\nlet chars = ['g', 'd', 'k', 'k', 'n'];\n\nlet hello: String = chars.iter()\n    .map(|&x| x as u8)\n    .map(|x| (x + 1) as char)\n    .collect();\n\nassert_eq!(\"hello\", hello);\n```\n\nIf you have a list of [`Result<T, E>`](https://doc.rust-lang.org/nightly/core/result/enum.Result.html)s, you can use `collect()` to\nsee if any of them failed:\n\n```rust\nlet results = [Ok(1), Err(\"nope\"), Ok(3), Err(\"bad\")];\n\nlet result: Result<Vec<_>, &str> = results.iter().cloned().collect();\n\n// gives us the first error\nassert_eq!(Err(\"nope\"), result);\n\nlet results = [Ok(1), Ok(3)];\n\nlet result: Result<Vec<_>, &str> = results.iter().cloned().collect();\n\n// gives us the list of answers\nassert_eq!(Ok(vec![1, 3]), result);\n```";
