+
+Basic syntax and snippet support for the Ebitengine Kage shading language. 
+
+<br>
+
+Ebitengine adopts an original shading language 'Kage'. This has a compatible syntax with Go, but the details are different. Kage has high portability. Ebitengine uses graphics libraries like OpenGL or Metal and this depends on environments, but Kage is compiled on the fly so that this works equally everywhere.
+
+### Installation
+
+[![](https://img.shields.io/badge/get%20it%20from-555555?style=for-the-badge&logo=vim&logoColor=60b371)![](https://img.shields.io/badge/vim.org-60b371?style=for-the-badge)](https://www.vim.org/scripts/script.php?script_id=6021)
+
+<details><summary>Manual installation</summary><br>
+  
+  Make sure you are using `vim > 8.0.2` with `python3` support. Building the latest version of vim:
+
+  ```
+  git clone https://github.com/vim/vim.git
+  cd vim/src/
+  ./configure --enable-python3interp
+  make
+  sudo make install
+  ```
+
+  Install `vim-plug` plugin manager:
+
+  ```
+  curl -fLo ~/.vim/autoload/plug.vim --create-dirs \
+  https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
+  ```
+
+  Install `vim-easycomplete` and `ultisnips` to support hints and snippets:
+
+  ```vim
+  Plug 'jayli/vim-easycomplete'
+  Plug 'SirVer/ultisnips'
+  ```
+
+  Install `sedyh/ebitengine-kage-support` to enable syntax highlighting and snippet support for Kage:
+
+  ```vim
+  Plug 'sedyh/ebitengine-kage-support', {'rtp': 'vim'}
+  ```

+
+## Known Issues
+
+The plugin will highlight complex numbers despite the fact that, at the moment, Kage does not support them.
+
+There are some problems with displaying scientific notation for floating point numbers (two numbers with the -+ operator without spaces will be highlighted as one).
