+# vim-javascript
+
+JavaScript bundle for vim, this bundle provides syntax highlighting and
+improved indentation.
+
+
+## Installation
+
+### Install with native package manager
+
+      git clone https://github.com/pangloss/vim-javascript.git ~/.vim/pack/vim-javascript/start/vim-javascript
+
+since Vim 8.
+
+### Install with [pathogen](https://github.com/tpope/vim-pathogen)
+
+      git clone https://github.com/pangloss/vim-javascript.git ~/.vim/bundle/vim-javascript
+
+alternatively, use a package manager like [vim-plug](https://github.com/junegunn/vim-plug)
+
+
+## Configuration Variables
+
+The following variables control certain syntax highlighting plugins. You can
+add them to your `.vimrc` to enable their features.
+
+-----------------
+
+```
+let g:javascript_plugin_jsdoc = 1
+```
+
+Enables syntax highlighting for [JSDocs](http://usejsdoc.org/).
+
+Default Value: 0
+
+-----------------
+
+```
+let g:javascript_plugin_ngdoc = 1
+```
+
+Enables some additional syntax highlighting for NGDocs. Requires JSDoc plugin
+to be enabled as well.
+
+Default Value: 0
+
+-----------------
+
+```
+let g:javascript_plugin_flow = 1
+```
+
+Enables syntax highlighting for [Flow](https://flowtype.org/).
+
+Default Value: 0
+
+-----------------
+
+```vim
+augroup javascript_folding
+    au!
+    au FileType javascript setlocal foldmethod=syntax
+augroup END
+```
+
+Enables code folding for javascript based on our syntax file.
+
+Please note this can have a dramatic effect on performance.
+
+
+## Concealing Characters
+
+You can customize concealing characters, if your font provides the glyph you want, by defining one or more of the following
+variables:
+
+    let g:javascript_conceal_function             = "ƒ"
+    let g:javascript_conceal_null                 = "ø"
+    let g:javascript_conceal_this                 = "@"
+    let g:javascript_conceal_return               = "⇚"
+    let g:javascript_conceal_undefined            = "¿"
+    let g:javascript_conceal_NaN                  = "ℕ"
+    let g:javascript_conceal_prototype            = "¶"
+    let g:javascript_conceal_static               = "•"
+    let g:javascript_conceal_super                = "Ω"
+    let g:javascript_conceal_arrow_function       = "⇒"
+    let g:javascript_conceal_noarg_arrow_function = "🞅"
+    let g:javascript_conceal_underscore_arrow_function = "🞅"
+
+
+You can enable concealing within VIM with:
+
+    set conceallevel=1
+
+OR if you wish to toggle concealing you may wish to bind a command such as the following which will map `<LEADER>l` (leader is usually the `\` key) to toggling conceal mode:
+
+    map <leader>l :exec &conceallevel ? "set conceallevel=0" : "set conceallevel=1"<CR>
+
+
+## Indentation Specific
+
+* `:h cino-:`
+* `:h cino-=`
+* `:h cino-star`
+* `:h cino-(`
+* `:h cino-w`
+* `:h cino-W`
+* `:h cino-U`
+* `:h cino-m`
+* `:h cino-M`
+* `:h 'indentkeys'`
+
+## Contributing
+
+Please follow the general code style
+guides (read the code) and in your pull request explain the reason for the
+proposed change and how it is valuable. All p.r.'s will be reviewed by a
+maintainer(s) then, hopefully, merged.
+
+Thank you!
