 #Angular Emoji Popup

+##Installation
+
+##Usage
+
+##How it works
+
+## Using MySQL for storage
+
+The following text is taken verbatim from [https://github.com/iamcal/js-emoji](https://github.com/iamcal/js-emoji)
+
+> Some special care may be needed to store emoji in your database. While some characters (e.g. Cloud, U+2601) are
+> within the Basic Multilingual Plane (BMP), others (e.g. Close Umbrella, U+1F302) are not. As such, 
+> they require 4 bytes of storage to encode each character. Inside MySQL, this requires switching from `utf8` 
+> storage to `utf8mb4`.
+
+> You can modify a database and table using a statement like:
+
+>  `ALTER DATABASE my_database DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;`
+>  `ALTER TABLE my_table CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;`
+
+> You will also need to modify your connection character set.
+
+> You don't need to worry about this if you translate to colon syntax before storage.
