+## Analytics
+
+Analytics will generate all you need to analyze UX with Matomo or Firebase Analytics. Input files are formatted in YAML. This command will generate a manager for each target and an AnalyticsManager. This is this one you will need to use. And it will generate a method for all tags you have declared in the YAML file. Next, you will need to use the `configure()` method of AnalyticsManager and if you want to use matomo to set up the `siteId` and the `url` of the site.
+
+```sh
+swift run -c release ResgenSwift strings tags $FORCE_FLAG "./Tags/tags.txt" \
+ --target "matomo firebase" \
+ --extension-output-path "./Analytics/Generated" \
+ --extension-name "AppAnalytics" \
+ --extension-suffix "GreatApp" \
+ --static-members true
+```
+ 
+ **Parameters**
+
+1. `-f`: force generation
+2. Input tags file (must be YAML formatted)
+3. `--target`: target with you will log UX
+4. `--extension-output-path`: path where to generate generated extension
+5. `--extension-name` *(optional)* : name of class to add the extension
+6. `--extension-suffix` *(optional)* : additional text which is added to filename (ex: `AppAnalytics+GreatApp.swift`)
+7. `--static-members` *(optional)*: generate static properties or not

+### YAML

+2. `name`: name of the tag
+3. `path` *(optional with firebase)* : needed for matomo but not with firebase (log screen)

+6. `tags`: which platform target
