+maybe # CRN List API
+
+A simple FastAPI application that serves the CRN list from a local JSON file.
+
+## Setup
+
+1. Install the required dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+2. Run the API server:
+
+```bash
+cd scripts/api/crn_list
+python crn_list.py
+```
+
+The server will start on port 8000 by default. You can specify a different port using the `PORT` environment variable:
+
+```bash
+PORT=8080 python crn_list.py
+```
+
+## Usage
+
+- The CRN list is available at: http://localhost:8000/crns.json
+- Documentation is available at: http://localhost:8000/docs
+
+## Configuring the Aleph Client SDK
+
+To make the Aleph client SDK use your local CRN list API instead of the production one, set the following environment variable:
+
+```bash
+export CRN_LIST_URL=http://localhost:8000/crns.json
+```
+
+## Modifying the CRN List
+
+To add or update test nodes in the CRN list, simply edit the `crn_list.json` file. The API will serve the updated content without requiring a restart.
