 There are two steps, first generating the docs and then running the web server.
 
-## Generating the docs
+## With docker compose (recommended)
 
-Regenerate the files with your local source code changes.
+1. Build the docs 
+    ```bash
+    docker compose build
+    ```
+2. Serve the docs
+    ```bash
+    docker compose up
+    ```
+3. Go to http://127.0.0.1:8080/swagger/index.html to view the docs
+    * If you get a Network error, replace the IP for the docker internal IP in the error, e.g: http://172.18.0.2:8080/swagger/index.html
+
+## Locally
+
+Install [go](https://go.dev/).
+
+### Generating the docs
 
 1. Set the current working dir to `src`
     ```bash
     cd src
     ```
 1. Run swag to generate the docs

+1. Set the current working dir to `src/docs`
+    ```bash
+    cd docs
+    ```
+1. Add the signal-cli receive V1 schemas
+    * Download the `signal-cli-x.y.z-json-schemas.tar.gz` schema files from https://github.com/Gara-Dorta/signal-cli/releases
+    * Extract the files
