This is a separate addition to RocketMap, adding some additional features such as map history or trainer history.

See the screenshots below:

1. Some basic understanding of web-technology (Sorry, I won't handhold you beyond this readme)
2. You need to have NPM installed (See: https://nodejs.org/en/ )
3. You need to have gulp installed globally (ie: npm install gulp -g)

1. Download RocketMapExtras and extract the files into a folder
2. Open gulp-config.json and correct the URL's there (Depending on your setup, you might not need to change the __GYMDATA_PATH__ value).
3. Go to the folder in terminal or command prompt and type: gulp build
4. A dist folder will be created, copy the contents to your webserver
5. Run /RocketMapExtras/GymData/create_tables.php once, then delete it from your server
6. Setup a cron or scheduled task that executes /RocketMapExtras/GymData/task.php periodically
