+- Solid syntax and indentation support (other features skipped). Only the best language packs.
 - All unnecessary files are ignored (like enormous documentation from php support).
 - No support for esoteric languages, only most popular ones (modern too, like `slim`).
 - Each build is tested by automated vimrunner script on CI. See `spec` directory.

 ## Installation
 
 1. Install [Pathogen](https://github.com/tpope/vim-pathogen), [Vundle](https://github.com/VundleVim/Vundle.vim), [NeoBundle](https://github.com/Shougo/neobundle.vim), or [Plug](https://github.com/junegunn/vim-plug) package manager for Vim.
 2. Use this repository as submodule or package.
 
+For example when using [Plug](https://github.com/junegunn/vim-plug):
+
+```
+Plug 'sheerun/vim-polyglot'
+```
+
 Optionally download one of the [releases](https://github.com/sheerun/vim-polyglot/releases) and unpack it directly under `~/.vim` directory.
 
+You can also use Vim 8 built-in package manager:
+
+```
+mkdir -p ~/.vim/pack/default/start
+git clone https://github.com/sheerun/vim-polyglot ~/.vim/pack/default/start/vim-polyglot
+```
+
+NOTE: Not all features of listed language packs are available. We strip them from functionality slowing vim startup in general (for example we ignore `plugins` folder that is loaded regardless of file type, use `ftplugin` instead).
+
+If you need full functionality of any plugin, please use it directly with your plugin manager.

+<!--/Language Packs-->
 
-## Disabling a language pack
+## Updating
 
-Individual language packs can be disabled by setting `g:polyglot_disabled`.
+You can either wait for new patch release with updates or run the `./build` script by yourself.
+
+## Troubleshooting
+
+Please make sure you have `syntax on` in your `.vimrc`, otherwise syntax files are not loaded at all.
+
+Individual language packs can be disabled by setting `g:polyglot_disabled` as follows:
 
 ```viml
 " ~/.vimrc
 let g:polyglot_disabled = ['css']
 ```
 
-Note that disabiling languages won't make in general your vim startup any faster / slower (only for specific file type). Vim-polyglot is selection of language plugins that are loaded only on demand.

 ## Contributing
 
 Language packs are periodically updated using automated `build` script.
 
-Feel free to add your language, and send pull-request.
+Feel free to add your language, and send pull-request.  In your pull request, please include:
+1. How you chose the particular repo from which to pull support for this language.
+2. An updated https://github.com/sheerun/vim-polyglot/blob/master/build .
+3. If at all possible, absolutely nothing else (in particular, please don't run `build` and include that in your PR).
+
+The easier it is to validate that the new language won't do anything wacky, the faster it'll be merged.  In particular, languages that utilize global plugins (loaded for every filetype), or plugins with dangerous features (like `call` based on the contents of a file being edited), will never be merged, as they will be slow or dangerous, respectively.
