+## Enabling document formatting
+
+To make the `eslint` server respond to `textDocument/formatting` LSP requests, you need to manually enable this
+setting. This is done when setting up the LSP server, like so:
+
+```lua
+local lsp_installer = require "nvim-lsp-installer"
+
+function common_on_attach(client, bufnr) ... end
+
+lsp_installer.on_server_ready(function (server)
+    local opts = {
+        on_attach = common_on_attach,
+    }
+
+    if server.name == "eslint" then
+        opts.on_attach = function (client, bufnr)
+            -- neovim's LSP client does not currently support dynamic capabilities registration, so we need to set
+            -- the resolved capabilities of the eslint server ourselves!
+            client.resolved_capabilities.document_formatting = true
+            common_on_attach(client, bufnr)
+        end
+        opts.settings = {
+            format = { enable = true }, -- this will enable formatting
+        }
+    end
+
+    server:setup(opts)
+end)
+```
+
+This will make `eslint` respond to formatting requests, for example when triggered through:
+
+-   `:lua vim.lsp.buf.formatting()`
+-   `:lua vim.lsp.buf.formatting_seq_sync()`
+-   `:lua vim.lsp.buf.formatting_sync()`
