+## Templates
+
+To add a new template, go to `templates` folder and create a new folder with the name of the template.
+
+Let's take the example of `plausible` template.
+
+1. create a folder in `templates/plausible`
+2. create a `docker-compose.yml` file inside the folder with the content of compose.
+3. create a `index.ts` file inside the folder with the following code as base:
+
+```typescript
+import {
+	generateHash,
+	generateRandomDomain,
+	type Template,
+	type Schema,
+} from "../utils";
+
+
+export function generate(schema: Schema): Template {
+	// do your stuff here, like create a new domain, generate random passwords, mounts.
+
+}
+```
+
+4. Now you need to add the information about the template to the `templates/templates.ts` is a object with the following properties:
+
+**Make sure the id of the template is the same as the folder name and don't have any spaces, only slugified names and lowercase.**
+
+```typescript
+{
+	id: "plausible",
+	name: "Plausible",
+	version: "v2.1.0",
+	description:
+		"Plausible is a open source, self-hosted web analytics platform that lets you track website traffic and user behavior.",
+	logo: "plausible.svg", // we defined the name and the extension of the logo
+	links: {
+		github: "https://github.com/plausible/plausible",
+		website: "https://plausible.io/",
+		docs: "https://plausible.io/docs",
+	},
+	tags: ["analytics"],
+	load: () => import("./plausible/index").then((m) => m.generate),
+},
+```
+
+5. Add the logo or image of the template to `public/templates/plausible.svg`
+
+
+### Recomendations
+- Use the same name of the folder as the id of the template.
+- The logo should be in the public folder.
+- Test first on a vps or a server to make sure the template works.
