+## drools_lsp
+
+https://github.com/kiegroup/drools-lsp
+
+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',
+    '-cp',
+    '/path/to/drools-lsp-server-jar-with-dependencies.jar',
+    'org.drools.lsp.server.Main',
+  },
+}
+
+-- Option 2) Specify just the jar location (the JAVA_HOME environment variable will be respected):
+require('lspconfig').drools_lsp.setup {
+  settings = {
+    drools = {
+      jar = '/path/to/drools-lsp-server-jar-with-dependencies.jar',
+    },
+  },
+}
+
+-- Option 3) Specify the jar location plus the java bin path and/or java opts:
+require('lspconfig').drools_lsp.setup {
+  settings = {
+    java = {
+      bin = '/path/to/java',
+      opts = { '-Xmx500m' },
+    },
+    drools = {
+      jar = '/path/to/drools-lsp-server-jar-with-dependencies.jar',
+    },
+  },
+}
+```
+
+It is also recommended to set up automatic filetype detection for drools (`*.drl`) files, for example:
+```vim
+autocmd BufRead,BufNewFile *.drl set filetype=drools
+```
+
+
+
+**Snippet to enable the language server:**
+```lua
+require'lspconfig'.drools_lsp.setup{}
+```
+
+
+**Default values:**
+  - `filetypes` : 
+  ```lua
+  { "drools" }
+  ```
+  - `on_new_config` : 
+  ```lua
+  see source file
+  ```
+  - `single_file_support` : 
+  ```lua
+  true
+  ```
