+# Authoring plugins
+
+## Process plugins
+
+To use process-based plugins, you must be using [Version
+2](../reference/config.html) of the configuration file. The top-level `plugins`
+array defines the available plugins and maps them to an executable on the system.
+
+In the `codegen` section, the `out` field dictates what directory will contain
+the new files. The `plugin` key must reference a plugin defined in the
+top-level `plugins` map. The `options` are serialized to a string and passed on
+to the plugin itself.
+
+```json
+{
+  "version": "2",
+  "plugins": [
+    {
+      "name": "jsonb",
+      "process": {
+        "cmd": "sqlc-gen-json"
+      }
+    }
+  ],
+   "sql": [
+    {
+      "schema": "schema.sql",
+      "queries": "query.sql",
+      "engine": "postgresql",
+      "codegen": [
+        {
+          "out": "gen",
+          "plugin": "jsonb",
+          "options": {
+            "indent": "  ",
+            "filename": "codegen.json"
+          }
+        }
+      ]
+    }
+  ]
+}
+```
+
+For a complete working example see the following files:
+- [sqlc-gen-json](https://github.com/kyleconroy/sqlc/tree/main/cmd/sqlc-gen-json)
+  - A process-based plugin that serializes the CodeGenRequest to JSON
+- [process_plugin_sqlc_gen_json](https://github.com/kyleconroy/sqlc/tree/main/internal/endtoend/testdata/process_plugin_sqlc_gen_json)
+  - An example project showing how to use a process-based plugin
+
+### Security
+
+Process-based plugins offer minimal security. Only use plugins that you trust.
+Better yet, only use plugins that you've written yourself.
