+# Firebase Integration Plugin
+
+This plugin is an example to integrate the `Firebase` library. This plugin just retrieves the data from the database specified and displays it in the plugin window. 
+
+## Install dependencies
+
+First ensure that your terminal is in the root of this project. Then:
+
+For `yarn` users, install all dependencies using:
+
+```
+yarn install
+```
+
+For `npm` users, install all dependencies using:
+
+```
+npm install
+```
+
+## Firestore Setup
+
+Next, you need to create a `.env` file containing all the variables. Enter all variables from your Firebase project:
+
+```sh
+{
+        echo 'API_KEY='
+        echo 'AUTH_DOMAIN='
+        echo 'PROJECT_ID='
+        echo 'STORAGE_BUCKET='
+        echo 'MESSAGING_SENDER_ID='
+        echo 'APP_ID='
+        echo 'COLLECTION_NAME='
+
+} >> .env
+
+## Build Process
+
+There are two ways to build the plugin for use in Photoshop:
+
+* `yarn watch` or `npm run watch` will build a development version of the plugin, and recompile everytime you make a change to the source files. The result is placed in `dist`. 
+* `yarn build` or `npm run build` will build a production version of the plugin and place it in `dist`. It will not update every time you make a change to the source files.
+
+> You **must** run either `watch` or `build` prior to trying to use within Photoshop!
+
+## Launching in Photoshop
+
+You can use the UXP Developer Tools to load the plugin into Photoshop.
+
+If the plugin hasn't already been added to your workspace in the UXP Developer Tools, you can add it by clicking "Add Plugin..." and selecting `dist/manifest.json`. **DO NOT** select the `manifest.json` file inside the `plugin` folder.
+
+Once added, you can load it into Photoshop by clicking the ••• button on the corresponding row, and clicking "Load". Switch to Photoshop and you should see the starter panels.
