+# How to add a new language
+
+In order to generate a client for a new language, here is a short guide:
+
+## Extract the template
+
+First you need to find your language in the list of generators:
+[list](https://openapi-generator.tech/docs/generators)
+
+Once you find your template you can extract it with the following command:
+```bash
+openapi-generator author template -g <your language generator> -o templates/<your language>
+```
+
+## Customize the template
+
+There are a few components to add before generating the client, mostly:
+- Init method
+- Retry strategy
+- maybe more
+
+### Init method
+
+By default, OpenAPI will put the `AppId` and `ApiKey` in every method, but we want an init method that takes those parameters and put them in the header of every requests, and create the right hosts.
+To do this, change the constructor of the client in the `mustache` file to accept and store them.
+
+### Retry strategy
+
+The retry strategy cannot be included in the OpenAPI spec, you need to add a `<your language>` folder inside the `complement` folder and add your retry strategy code in that folder.
+
+TODO finish this when we have more knowledge about the other languages.
