+# Friendly Snippets
+
+Snippets collection for a set of different programming languages for faster development.
+
+The only goal is to have one community driven repository for all kinds of
+snippets in all programming languages, this way you can have it all in one
+place.
+
+### Usage
+
+This collection of snippets should work with any plugin that supports loading
+vscode snippets. Like for example:
+
+- [vim-vsnip](https://github.com/hrsh7th/vim-vsnip)
+- [LuaSnip](https://github.com/L3MON4D3/LuaSnip)
+- [coc-snippets](https://github.com/neoclide/coc-snippets)
+
+### Add snippets from a framework to a filetype.
+
+There's extra snippets included in this repo but they are not added by default,
+since it would be irrelevant for people not using those frameworks. See
+[`snippets/frameworks`](https://github.com/rafamadriz/friendly-snippets/tree/main/snippets/frameworks)
+
+For example: if you want to add rails snippets to ruby.
+
+With LuaSnip:
+
+```lua
+require'luasnip'.filetype_extend("ruby", {"rails"})
+```
+
+This method is going to work globally on all open buffers with `ruby` filetype.
+Alternatively you can do `set filetype=ruby.rails` so it only works on a
+specific buffer, but this is going to mess up with syntax highlighting.
+
+With vim-vsnip:
+
+```viml
+let g:vsnip_filetypes.ruby = ['rails']
+```
+
+For more info related to this change see [#88](https://github.com/rafamadriz/friendly-snippets/issues/88)
+
+### Install
+
+Use your plugin manager of choice, e.g.
+
+```lua
+-- Packer
+use "rafamadriz/friendly-snippets"
+
+-- Plug
+Plug 'rafamadriz/friendly-snippets'
+
+-- If you're using coc.nvim, you can use:
+CocInstall https://github.com/rafamadriz/friendly-snippets@main
+```
