+# Plugins
+I use quite a lot of plugins, as they greatly improve my workflow or just add
+features that you most definitely need if you want to use Vim as your main
+editor.
+
+## List of plugins
+
+* [CoC](https://github.com/neoclide/coc.nvim): my autocomplete plugin of
+  choice. It provide full LSP support, so many of its plugins use the exact
+  same setup as a VSCode plugin.
+* [CtrlP](https://github.com/ctrlpvim/ctrlp.vim): a fuzzy search tool which I
+  use for most navigation.
+* [vim-fugitive](https://github.com/tpope/vim-fugitive): an amazing Git client
+  for Vim. It has support for all the usual stuff (commits, adding/removing
+  files etc.), as well as a merge conflict resolver using Vim's built-in diff
+  view.
+* [vim-surround](https://github.com/tpope/vim-surround): adds mappings to
+  change/remove surrounding characters (e.g. (), "", '' etc.). It integrates
+  really well with already existing bindings, making it feel like it's a
+  built-in feature.
+* [vim-commentary](https://github.com/tpope/vim-commentary): adds mappings for
+  commenting/uncommenting lines easily. It has support for basically all
+  languages I ever use.
+* [tagbar](https://github.com/preservim/tagbar): a sidebar chowing you the
+  layout of the current file. It helps me orient myself within the file/class
+  I'm currently working on, as well as easing the movement between
+  classes, functions etc...
+* [vim-gitgutter](https://github.com/airblade/vim-gitgutter): shows Git
+  diff markers in the sidebar.
+* [indentline](https://github.com/Yggdroot/indentLine): shows a visual line to
+  indicate which lines are on the same indentation level.
+* vim-python-pep8-indent: makes Vim properly indent Python according to PEP8
+* [vim-indent-object](https://github.com/michaeljsmith/vim-indent-object):
+  allows you to select the current indentation block using the same bindings as
+  paragraphs, inner brackets, etc...
+* NERDTree: file browser, useful for getting your bearings in a large project.
+* [vim-toml](https://github.com/cespare/vim-toml): syntax highlighting for toml
+  files
+* [auto-pairs](https://github.com/jiangmiao/auto-pairs): auto-insert matching
+  pairs
+* [Tabular](https://github.com/godlygeek/tabular): useful plugin for aligning
+  text
+* [haskell-vim](https://github.com/neovimhaskell/haskell-vim): indentation for
+  Haskell
+* [ion-vim](https://github.com/vmchale/ion-vim): syntax highlighting for the
+  [ion shell](https://github.com/redox-os/ion) (my current shell).
