+![GitHub](https://img.shields.io/github/license/narwassco/vt)
+![Docker Cloud Automated build](https://img.shields.io/docker/cloud/automated/narwassco/vt)
+![Docker Image Size (latest by date)](https://img.shields.io/docker/image-size/narwassco/vt)
+
+This is to manage vectortiles for Narok Water in Github pages.
+
+## Configuration
+All the settings are in `config.js` and `config-search.js`, so please make sure your own settings on this file before producing vector tile.
+
+Please put environment variable for database settings.
+```
+db_user=$db_user
+db_password=$db_password
+db_host=host.docker.internal
+db_post=5432
+```
+
+## Create mbtiles
+### Usage (Docker)
+
+```
+db_user=your user db_password=your password docker-compose up
+```
+
+Your mbtiles will be generated under `data` directory.
+
+### Usage (Nodejs)
+
+#### Requirements
+
+This module uses [`tippecanoe`](https://github.com/mapbox/tippecanoe) to convert geojson files to mbtiles. Please make sure to install it before running.
+
+for MacOS
+```
+$ brew install tippecanoe
+```
+
+for Ubuntu
+```
+$ git clone https://github.com/mapbox/tippecanoe.git
+$ cd tippecanoe
+$ make -j
+$ make install
+```
+
+Then,
+
+```
+$ npm install
+
+$ db_user=$db_user \
+  db_password=$db_password \
+  db_host=localhost \
+  db_port=5432 \
+  npm run create
+```
+
+There will be two files as follows.
+- ./data/rwss.mbtile
+- ./public/wss.geojson
+
+## Extract pbf (mvt) tiles from mbtiles file
+please configure `config-extact.js` file to adjust output directory path and input mbtiles path.
+
+```
+npm run extract
+```
+
+There will be vectortiles under `./public/tiles` directory.
+
+## Deploy
+
+```
+npm run deploy
+```
+
+It will publish all the files under `public` directory to Github Pages.
+
+# Using Github Action
+
+We can use Github Action for `npm run extract` and `npm run deploy` process.
+
+So, you can just push `data/narok.mbtiles` and `public/meter.geojson` to master repository.
