-To target a specific version on Metals, set the following.
-If nothing is set, the latest stable will be used.
-```vim
-let g:metals_server_version = '0.8.4+106-5f2b9350-SNAPSHOT'
-```
-
 Scala language server with rich IDE features.
-`metals` can be installed via `:LspInstall metals`.
+
+See full instructions in the Metals documentation:
+
+https://scalameta.org/metals/docs/editors/vim.html#using-an-alternative-lsp-client
+
+Note: that if you're using [nvim-metals](https://github.com/scalameta/nvim-metals), that plugin fully handles the setup and installation of Metals, and you shouldn't set up Metals both with it and this plugin.
+
+To install Metals, make sure to have [coursier](https://get-coursier.io/docs/cli-installation) installed, and once you do you can install the latest Metals with `cs install metals`. You can also manually bootstrap Metals with the following command.
+
+```bash
+cs bootstrap \
+  --java-opt -Xss4m \
+  --java-opt -Xms100m \
+  org.scalameta:metals_2.12:<enter-version-here> \
+  -r bintray:scalacenter/releases \
+  -r sonatype:snapshots \
+  -o /usr/local/bin/metals -f
+```
