README.md

@@ -26,6 +26,45 @@ I will first focus on widely used and well known config files.
 
 You are welcome to request any config file, as far as it's fairly well known.
 
+## Installation
+
+Download the latest binary from the [releases page](https://github.com/Myzel394/config-lsp/releases) and put it in your PATH.
+
+Follow the instructions for your editor below.
+
+### Neovim installation
+
+Using [nvim-lspconfig](https://github.com/neovim/nvim-lspconfig) you can add `config-lsp` by adding the following to your `lsp.lua` (filename might differ):
+
+```lua
+if not configs.config_lsp then
+    configs.config_lsp = {
+        default_config = {
+            cmd = { 'config-lsp' },
+            filetypes = {
+                "sshconfig",
+                "sshdconfig",
+                "fstab",
+                "aliases",
+                -- Matches wireguard configs and /etc/hosts
+                "conf",
+            },
+            root_dir = vim.loop.cwd,
+        },
+    }
+end
+
+lspconfig.config_lsp.setup {}
+`````
+
+### VS Code installation
+
+The VS Code extension is currently in development. An official extension will be released soon.
+
+However, at the moment you can also compile the extension yourself and run it in development mode.
+
+**Do not create an extension and publish it yourself. Contribute to the official extension instead.**
