 npm install -g @urbit/hoon-language-server
 ```
 
-Make sure you have a fake ~zod running on localhost:8080 and you've installed a
-Hoon plugin for your editor, like hoon.vim.
+This installs `hoon-language-server` which allows your code editor to communicate with an urbit ship running locally on your development machine.
 
-To use with nvim-lspconfig:
+The default options are: `-p 80 -d 0 -u http://localhost -s zod -c lidlut-tabwed-pillex-ridrup`
 
-Add a snippet to init.vim:
+- `-p` is the port your ship is accessible on over HTTP
+- `-d` is the delay for running didSave events
+- `-u` is the URL of your ship
+- `-s` is the `@p` of your ship (without a sig)
+- `-c` is the `+code` of the running urbit (also without a sig)
+
+## Urbit Setup
+
+You must have a fake ship running and it must be running the hoon language server.  To create and start a fake `~zod`:
+
+```
+urbit -F zod -c zod
+```
+
+In the urbit dojo, start the language server:
+
+```
+|start %language-server
+```
+
+If you need the passcode for your ship, enter this in dojo:
+
+```
++code
+```
+
+To start the same ship again in the future just run:
+
+```
+urbit zod
+```
+
+in the same directory you created it in.
+
+## Editor Setup
+
+Your code editor now needs to use `hoon-language-server` as an LSP provider.  There are plugins for common editors that add syntax highlighting, etc. and help connect to the language server.

+### VSCode
+
+ * [hoon-vscode](https://github.com/famousj/hoon-vscode)
+ * [hoon-assist-vscode](https://github.com/urbit/hoon-assist-vscode)
+
+### Emacs
+
+ * [hoon-mode.el](https://github.com/urbit/hoon-mode.el)
+
+### Vim
+
+ * [hoon.vim](https://github.com/urbit/hoon.vim)
+
+`hoon.vim` does not use the language server itself, but the github page describes a setup using `vim-lsp`.
+
+### Neovim
+
+Neovim users should use [hoon.vim](https://github.com/urbit/hoon.vim) with one of the following LSP setups:
+
+#### Native LSP
+
+Install [nvim-lspconfig](https://github.com/neovim/nvim-lspconfig) to simplify your local configuration.  To use the [default configuration](https://github.com/neovim/nvim-lspconfig/blob/master/doc/server_configurations.txt#hoon_ls), add the following to `init.lua`:
+
+```
+require'lspconfig'.hoon_ls.setup{}
+```
+
+To modify the default options use:
 
 ```
-lua << EOF
 require'lspconfig'.hoon_ls.setup{
   cmd = {"hoon-language-server" "-p", "80", "-d", "500", -s "zod", "-u", "http://localhost", "-c" "lidlut-tabwed-pillex-ridrup"},
   filetypes = {"hoon"},
   single_file_support = true
 }
+```
+
+You can include lua snippets in your `init.vim` like so:
+
+```
+lua << EOF
+require'lspconfig'.hoon_ls.setup{}
 EOF
 ```
 
-Note that the values provided above are for reference, you can choose to provide no flags/values and use the defaults or set your own.
+Alternatively, configure native LSP manually without additional plugins:
 
-The default values are: `-p 80 -d 0 -u http://localhost -s zod -c lidlut-tabwed-pillex-ridrup`
+```
+-- Only `configs` must be required, util is optional if you are using the root resolver functions, which is usually the case.
+local configs = require ('lspconfig.configs')
+local util = require ('lspconfig.util')
 
-- `-p` is the port your ship is accessible on over HTTP
-- `-d` is the delay for running didSave events
-- `-u` is the URL of your ship
-- `-s` is the `@p`` of your ship (without a sig)
-- `-c` is the `+code` of the running urbit (also without a sig)
+configs['hoon_ls'] = {
+  default_config = {
+    cmd = { 'hoon-language-server', "-p", "8080" },
+    filetypes = { 'hoon' },
+    single_file_support = true,
+    root_dir = function(fname)
+      return util.find_git_ancestor() or vim.loop.os_homedir()
+    end,
+  },
+  docs = {
+    description = [[
+      https://github.com/urbit/hoon-language-server
+    ]],
+  },
+}
+```
+
+#### coc.nvim
+
+Install and configure [coc.nvim](https://github.com/neoclide/coc.nvim), then add a `languageserver` entry to `~/.config/nvim/coc-settings.json`:
+
+```
+{
+  "languageserver": {
+    "hoon-language-server": {
+      "command": "hoon-language-server",
+      "args": ["-p", "8080"],
+      "filetypes": ["hoon"]
+    }
+  }
+}
+```
