   * `CORS_ALLOW_ORIGIN` (`*`) - The list of sites that are allow to make requests
 
+##### `dbsize` (Database Size)
+  Show size of Nightscout Database, as a percentage of declared available space or in MiB.
+
+  Many deployments of Nightscout use free tier of MongoDB on Heroku, which is limited in size. After some time, as volume of stored data grows, it may happen that this limit is reached and system is unable to store new data. This plugin provides pill that indicates size of Database and shows (when configured) alarms regarding reaching space limit.
+
+  **IMPORTANT:** This plugin can only check how much space database already takes, _but cannot infer_ max size available on server for it. To have correct alarms and realistic percentage, `DBSIZE_MAX` need to be properly set - according to your mongoDB hosting configuration.
+
+  **NOTE:** It may happen that new data cannot be saved to database (due to size limits) even when this plugin reports that storage is not 100% full. MongoDB pre-allocate data in advance, and database file is always made bigger than total real data size. To avoid premature alarms, this plugin refers to data size instead of file size, but sets warning thresholds low. It may happen, that file size of database will take 100% of allowed space but there will be plenty of place inside to store the data. But it may also happen, with file size is at its max, that data size will be ~70% of file size, and there will be no place left. That may happen because data inside file is fragmented and free space _holes_ are too small for new entries. In such case calling `db.repairDatabase()` on mongoDB is recommended to compact and repack data (currently only doable with third-party mongoDB tools, but action is planned to be added in _Admin Tools_ section in future releases).
+  
+  All sizes are expressed as integers, in _Mebibytes_ `1 MiB == 1024 KiB == 1024*1024 B`
+
+  * `DBSIZE_MAX` (`496`) - Maximal allowed size of database on your mongoDB server, in MiB. You need to adjust that value to match your database hosting limits - default value is for standard Heroku mongoDB free tier.
+  * `DBSIZE_WARN_PERCENTAGE` (`60`) - Threshold to show first warning about database size. When database reach this percentage of `DBSIZE_MAX` size - pill will show size in yellow. 
+  * `DBSIZE_URGENT_PERCENTAGE` (`75`) - Threshold to show urgent warning about database size. When database reach this percentage of `DBSIZE_MAX` size, it is urgent to do backup and clean up old data. At this percentage info pill turns red.
+  * `DBSIZE_ENABLE_ALERTS` (`false`) - Set to `true` to enable notifications about database size.
+  * `DBSIZE_IN_MIB` (`false`) - Set to `true` to display size of database in MiB-s instead of default percentage.
+  
+  This plugin should be enabled by default, if needed can be diasabled by adding `dbsize` to the list of disabled plugins, for example: `DISABLE="dbsize"`.
+
 #### Extended Settings
   Some plugins support additional configuration using extra environment variables.  These are prefixed with the name of the plugin and a `_`.  For example setting `MYPLUGIN_EXAMPLE_VALUE=1234` would make `extendedSettings.exampleValue` available to the `MYPLUGIN` plugin.

+How to upgrade icons in icon-fonts on Nightscout
+================================================
+
+This guide is fol developers regarding how to add new icon to Nightscout.
+
+Nightscout use icon fonts to render icons. Each icon is glyph (like - letter, or more like emoji character) inside custom made font file.
+That way we have nice, vector icons, that are small, scalable, looks good on each platform, and are easy to embed inside CSS.
+
+To extend existing icon set.:
+
+1. Prepare minimalist, black & white icon in SVG tool of choice, and optimize it (you can use Inkscape) to be small in size and render good at small sizes.
+2. Use https://icomoon.io/app and import accompanied JSON project file (`Nightscout Plugin Icons.json`)
+3. Add SVG as new glyph. Remember to take care to set proper character code and CSS name
+4. Save new version of JSON project file and store in this folder
+5. Generate font, download zip file and unpack it to get `fonts/pluginicons.svg` and `fonts/pluginicons.woff`
+6. Update `statc/css/main.css` file
+   * In section of `@font-face` with `font-family: 'pluginicons'`
+     * update part after `data:application/font-woff;charset=utf-8;base64,` with Base64-encoded content of just generated `pluginicons.woff` font
+     * update part after `data:application/font-svg;charset=utf-8;base64,` with Base64-encoded content of just generated `pluginicons.svg` font
+   * copy/update all entries `.plugicon-****:before { content: "****"; }` from generated font `style.css` into `statc/css/main.css`
+7. Do not forget to update `Nightscout Plugin Icons.json` in this repo (´download updated project from icomoon.io)
+   
+Hints
+-----
+
+* You can find many useful online tools to encode file into Base64, like: https://base64.guru/converter/encode/file
+* Do not split Base64 output - it should be one LONG line
+* Since update process is **manual** and generated fonts & updated CSS sections are **binary** - try to avoid **git merge conflicts** by speaking with other developers if you plan to add new icon
+* When in doubt - check `git log` and reach last contributor for guidelines :)
