+
+Language server for the [Drools Rule Language (DRL)](https://docs.drools.org/latest/drools-docs/docs-website/drools/language-reference/#con-drl_drl-rules).
+
+The `drools-lsp` server is a self-contained java jar file (`drools-lsp-server-jar-with-dependencies.jar`), and can be downloaded from [https://github.com/kiegroup/drools-lsp/releases/](https://github.com/kiegroup/drools-lsp/releases/).
+
+Configuration information:
+```lua
+-- Option 1) Specify the entire command:
+require('lspconfig').drools_lsp.setup {
+  cmd = { '/path/to/java', '-jar', '/path/to/drools-lsp-server-jar-with-dependencies.jar' },
+}
+
+-- Option 2) Specify just the jar path (the JAVA_HOME environment variable will be respected if present):
+require('lspconfig').drools_lsp.setup {
+  drools = { jar = '/path/to/drools-lsp-server-jar-with-dependencies.jar' },
+}
+
+-- Option 3) Specify the java bin and/or java opts in addition to the jar path:
+require('lspconfig').drools_lsp.setup {
+  drools = {
+    java = { bin = '/path/to/java', opts = { '-Xmx100m' } },
+    jar = '/path/to/drools-lsp-server-jar-with-dependencies.jar',
+  },
+}
+```
+
+Neovim does not yet have automatic detection for the `drools` filetype, but it can be added with:
+```lua
+vim.cmd [[ autocmd BufNewFile,BufRead *.drl set filetype=drools ]]
+```
+]=],
+  },
