+# Enterprise Release Publisher
+A script that reads the configuration file in your Android project, builds the defined module/variant combination and then uploads it to the specified server using the defined file name and also updates the JSON file on the remote with the same file name.
+
+## Configuration
+To use the script for your project, you have to add a configuration file called `enterprise-releases.json` in the root of your project directory.
+This file can contain multiple release configurations and needs to specify a couple of key values:
+```json
+{
+    "DEV": {
+        "module": "app",
+        "variant": "debug",
+        "server": "sftp://127.0.0.1",
+        "path": "/var/www/apps/projects/test",
+        "fileName": "Enterprise-Test"
+    },
+    "INT": {
+        "module": "app",
+        "variant": "release",
+        "server": "sftp://127.0.0.1",
+        "path": "/var/www/apps/projects/test",
+        "fileName": "Enterprise-Test"
+    }
+}
+```
+- `module`: specifies the module built with Gradle
+- `variant`: the variant that should be built. it's combined with the module from above to create the proper Gradle command, e.g. `:app:assembleDebug`
+- `server`: the server (including protocol) to upload the files to
+- `path`: the path on the remote server where the files should be placed
+- `fileName`: the name to be used for the apk & json files on the remote
+
+If there's only one release configuration defined, it will automatically pick that one. In case there are multiple configurations you have to add the configuration name you want to build & upload as argument (see examples below).
+
+## Example Usage
+Simply execute the script in the root directory of your project, optionally specifying the configuration to use if there are multiple.
+```bash
+erp.clj
+erp.clj "INT"
+```
+
+##
+### SSH Configuration
+I'm assuming that you've properly defined your credentials in `~/.ssh/config`, so you don't have to specify any credentials in your configuration files. You can assign specific credentials to different hosts there.
+
+```
+Host SERVER
+     User USER
+     IdentityFile PATH_TO_KEY
+```
+
+### Fish
+If you don't want to add the script itself to your path you can also create a fish function to use it from any directory.
+
+```
+function erp
+    PATH_TO_SCRIPT/erp.clj $argv[1]
+end
+
+funcsave erp
+```
