 Let us know if you want to suggest improvements for the README and open a merge request (which is just like Github's pull request)

 ## How can I condripute?

-### Your First Code Condripution
+We are an open source project and we highly appreciate contributions. At the same time please keep some things in mind: :heart:

-We are fans of labels, at least for our issues. You can find a list of `newbie` issues [here](https://gitlab.com/bloodyhealth/drip/issues?label_name%5B%5D=Newbie).
-If you decide to work on an issue, please click on `Create branch` based on that issue. You can find this as a dropdown option right under `Create merge request`.
-This allows us to keep track of the issues that are related to an existing branch and tells everyone "somebody is working on it".
+- The drip maintainers are usually around 2-3 people and are responsible for everything from developing new features to answering press inquiries or fixing bugs. Most of this work is done unpaid. (If you write a nice email your chances to get an answer are much higher than if you behave like a tech bro.)
+- We have a plan for the direction in which drip should evolve. This means that even if it isn't always transparent on gitlab, we have a list of features that we are building and more importantly, which bugs need to be fixed and which dependencies need to be updated.
+- drips core values are:
+  - 🔮 open source
+  - 🩸 feminist and gender inclusive
+  - 🔒 secure: data entered stays with that person/on their device
+  - 🔬 science-based: we implemented the sympto-thermal method

-If you want to open a merge request, yeah :tada: exciting! We are using a template for merge requests to make sure we explain what we have done and why.
-Keep in mind that people who will review your merge request are more motivated to do so when the merge request is well explained and ideally not too big.
+This means that we will never implement anything that contradicts these core values. Some examples: We will never build a cloud integration, we will never make an ovulation prediction.

-### Reporting Bugs
+- If you would like to make a sustainable contribution to the project, we would be happy to join the game.

-You found a bug :bug:? Please feel free to investigate and save logs for more specific details.
+### Reporting Bugs or Making Suggestions

-Before creating a new issue, please review the [list of existing issues](https://gitlab.com/bloodyhealth/drip/issues) to make sure the bug is unknown. You are invited to describe the bug in all its details e.g. in what context/settings has it occurred?
+If you found a bug or have suggestions, please :one: first review the [list of existing issues](https://gitlab.com/bloodyhealth/drip/issues) to make sure the bug/suggestion is unknown; :two: after that, take time to investigate and write a detailed issue report. Best you use our [templates for bug /chore/ feature](https://gitlab.com/bloodyhealth/drip/-/tree/main/.gitlab/issue_templates) (you can choose when creating a new issue) in gitlab or send us an email to our [gitlab email](mailto:incoming+bloodyhealth/drip@incoming.gitlab.com). It will automagically add a new issue to the list with a description text taken from the body of your email. Please attach screenshots or other helpful things.

-To send us a new issue you can also use our [gitlab email](mailto:incoming+bloodyhealth/drip@incoming.gitlab.com). It will automagically add a new issue to the list with a description text taken from the body of your email.
+### Your First Condripution

-### Suggesting Enhancements
-
-Do you have suggestions for enhancing the app or for cleaning up some code? Fantastic!
-
-Before creating a new issue, please review the [list of existing issues](https://gitlab.com/bloodyhealth/drip/issues) to make sure nobody else had the same idea before you! You are then invited to open a new issue with a somewhat extensive description, you can use emojis or GIFs if it helps :)!
-
-To send us a new issue you can also use our [gitlab email](mailto:incoming+bloodyhealth/drip@incoming.gitlab.com). It will automagically add a new issue to the list with the title taken from the subject line and the description text for the issue taken from the body of your email.
+- If you want to contribute to drip's code or translation, please get in touch with us. We can tell you if someone is already working on something similar, if your idea does (not) match drip's core values, etc. Of course, you can always create a drip version for your private use with anything you want, but please don't expect us to review and merge code that has not been discussed before.
+- If you want to open a merge request, yeah :tada: exciting! We are using a template for merge requests to make sure we explain what we have done and why.
+- Keep in mind that people who will review your merge request are more motivated to do so when the merge request is well explained and ideally not too big.

 ## Development setup

-#### 1. Android Studio
-
-Install [Android Studio](https://developer.android.com/studio/) - you'll need it to install some dependencies.
-
-#### 2. Node & npm version
-
-Make sure you are running Node 14 and npm 6.14.17. It's easiest to switch Node versions using `nvm`, here's how to do it:

+# How to release

-Note: You need the release-key to bundle a release that can be uploaded to Google Play Store.
+drip is developed in React Native for iOS and Android and is released on 4 different platforms:

-Run the release wizard that takes you through all the steps necessary to prepare a new release:
+1. [Google Play Store](https://play.google.com/store/apps/details?id=com.drip)
+2. [Apple App Store](https://apps.apple.com/us/app/drip/id1584564949)
+3. [F-Droid](https://f-droid.org/packages/com.drip/)
+4. [drip Website](https://dripapp.org)
+
+In an ideal world the app version is the same across platforms. In reality this has never been the case.
+
+Releasing a new version is very exciting and brings happy changes like fixing a bug, improving a feature, updating dependencies or adding a new functionality to the app. It is more than just pressing the button "publish new version".
+
+_Note_: You need the release-key for Android to bundle a signed release that can be uploaded and published via the Google Play Store. A similar process for Apple requires a certificate to upload and publish the app to the App Store.

+
+## Version updating
+
+When you are done with a chore, a feature or a bugfix, you may want to share it with testers and eventually publish a release. In order to identify a specific app version we can update the version name, which is created based on the following format: `1.yymm.d` e.g. `1.2311.7`. If you want to upload a new app version to Google Play you also need to update the version code.
+
+The following command will:
+
+- create a new versionName and a new higher versionCode (+1)
+- create a commit including a tag named after the new release version name.

 ```
-npm run release
-```
-This will trigger the following:
-* update version number
-* create a new tag for the release
-* update the changelog
-* make a release commit
-
-To then bundle a release run the following command on your branch:
-
-```
-cd android && ./gradlew bundleRelease
+yarn release
 ```

-This command creates an `app.aab` file in the folder `/android/app/build/outputs/bundle/release`.
+The versionName and versionCode [are defined here](https://gitlab.com/bloodyhealth/drip/-/blob/5401789c46f4a02915ab900ef284581be420451c/android/app/build.gradle#L137-138) and in [package.json](https://gitlab.com/bloodyhealth/drip/-/blob/5401789c46f4a02915ab900ef284581be420451c/package.json#L3).

-[More on Android App Bundle](https://blog.swmansion.com/make-your-react-native-app-3x-smaller-44c993eda2c9)
+**Note for iOS**

-You need to manually push the created tag to Gitlab:
+Update the version number for iOS in `ios/drip/Info.plist` under:

 ```
-git push origin <tagname>
+<key>CFBundleShortVersionString</key>
+<string>1.2403.19</string>
 ```
-Also don't forget to push your branch to Gitlab and review and merge it if ready!

-Yay, done (have a scoop of ice cream, I suggest coconut 🍦)!
+### Android builds
+
+APK versus AAB
+
+> Android App Bundles (AAB) include all your app’s compiled code and resources, but defer APK generation and signing to Google Play. Unlike an APK, you can't deploy an app bundle directly to a device. So, if you want to quickly test or share an APK with someone else, you should instead build an APK.
+
+(https://developer.android.com/build/building-cmdline)
+
+#### APK
+
+To build a release apk file, run the following command:
+
+```
+yarn build-android-apk-release
+```
+
+_which is a shortcut for:_ `cd android && ./gradlew clean && ./gradlew assembleRelease && cd ..`
+
+This will create a new apk file named `app-release.apk` under `./android/app/build/outputs/apk/release/`.
+
+For signing an apk you can run this command:
+
+```
+yarn sign-android-apk-release
+```
+
+_which is a shortcut for:_ `zipalign -v -p 4 ./android/app/build/outputs/apk/release/app-release.apk ./android/app/build/outputs/apk/release/app-release_signed.apk`
+
+It adds a file name `app-release_signed.apk` in the same folder in `./android/app/build/outputs/apk/release/`
+
+#### AAB
+
+To build a release aab file, run:
+
+```
+yarn build-android-aab-release
+```
+
+_which is a shortcut for:_ `cd android && ./gradlew clean && ./gradlew :app:bundleRelease && cd ..`
+
+It creates a new aab file named `app-release.aab` under `./android/app/build/outputs/bundle/release`
+
+For signing an aab you first need to configure the base module’s build.gradle file with your app’s signing information. You can then run this command:
+
+```
+yarn sign-android-aab-release
+```
+
+_which is a shortcut for:_ `jarsigner -keystore ./android/app/drip-release-key.keystore ./android/app/build/outputs/bundle/release/app-release.aab drip-release-key`
+
+### iOS builds
+
+To build an .ipa archive file for an upload to the AppStore you need to go to xCode and select Build -> "Any iOS Device" and under "Product" -> "Archive".
+
+Once the archiving process has completed you can chose to do the following:
+
+"Distribute the app"
+
+- TestFlight & App Store for when you want to upload it for external testing and/or production release
+- TestFlight Internal Only for when you want to upload it for internal testing
+
+## User testing
+
+To enable external testing you need to remember that Google Play and Apple App Store might take up to 1 day for their review process. "External testing" for iOS allows testing drip on Testflight anonymously via a public link. "Open testing" for Android allows testing drip on Google Play as beta tester below the normal production listing.
+
+For a quick and easy way to share an apk to testers who are willing to sideload drip onto their Android phones, do this: Upload a signed apk to the Gitlab repository of the drip website under `/release` https://gitlab.com/bloodyhealth/bloodyhealth.gitlab.io/-/tree/main/release and maybe adapt the name of the apk with a more specific name than "app-release.apk". Now you can simply share a direct link to download your newly bundled apk, e.g. [a download link for v1.2311.14](https://gitlab.com/bloodyhealth/bloodyhealth.gitlab.io/-/blob/main/release/v1.2311.14.apk).
+
+## Changelog
+
+The [changelog](https://gitlab.com/bloodyhealth/drip/-/blob/main/CHANGELOG.md) should reflect the technical / code changes between a previous and the new version. Please update the changelog file with any relevant additions, fixes and changes in the following format:
+
+**v1.yymm.d**
+
+**Changes**
+
+Changing the color of funky button
+Updating a library from 1.2.3 to 2.3.4
+
+**Adds**
+
+New feature for calendar
+
+**Fixed**
+
+Small bug in chart
+
+## Release notes
+
+These notes are for the users and curious ones who may want to start using drip. They should be based on the changelog but written in a friendly and easy to understand way. The focus is on the user perspective and the impact of the changes for the user. Behind the scenes and in depth code changes are less relevant.
+
+Google Play limits these notes to 500 characters, whereas Apple's App Store limits these notes to 4.000 characters. In Fdroid there are no release notes.
+
+## Release tag
+
+[Tags](https://gitlab.com/bloodyhealth/drip/-/tags) can mark a specific point in the coding/commmit history and helps us identify the version status of a released app. They are named "iOS-v1.2401.17" or "Release-v1.yymm.d".
+
+## Phone screenshots
+
+If there are visual changes in the app you may want to update the screenshots for the Google Play Store listing, which allows up to 8 and for Apple's App Store, which allows up to 10 screenshots. Keep in mind that both Google Play and Apple have specific resolution requirements. You'll find Google's in Grow -> Store presence -> Main Store Listing -> Phone screenshots and Apple's on the main App Store Connect site. Here is a link for [Apple's screenshot specifications](https://developer.apple.com/help/app-store-connect/reference/screenshot-specifications).
+
+Please also update [phone screenshots for the website](https://gitlab.com/bloodyhealth/bloodyhealth.gitlab.io/-/tree/main/assets) and set links on [/index](https://gitlab.com/bloodyhealth/bloodyhealth.gitlab.io/-/blob/f3da9776b1943ffa32458e74ef86eeca98c1891c/index.html#L47) and [/media](https://gitlab.com/bloodyhealth/bloodyhealth.gitlab.io/-/blob/c7f999bb7ad736345321537cbffa3f4c24eeee6d/media.html#L33) that can then also be attached to a social media post.
+
+## Publishing
+
+### Google Play Console
+
+Upload a signed aab to the [Google Play Console for developers](https://play.google.com/console/) and add it to the "App bundle explorer". This requires a higher versionCode and a different version name compared to previously uploaded aab or apk files.
+You can decide if you want the new app version to get released for testing (internal, closed or open) or for production. Keep in mind that any track other than "internal testing" triggers an external review by Google and might take a few hours.
+
+### Apple App Store Connect
+
+Upload a new version and submit it for review, before it can be published.
+
+### drip website
+
+After a new version has been published on Google Play (or F-Droid) the apk version that is downloadable directly from the [drip website](https://dripapp.org) needs to get updated as well. Therefore you upload a signed apk to the [repository](https://gitlab.com/bloodyhealth/bloodyhealth.gitlab.io/) as [we did in this commit](https://gitlab.com/bloodyhealth/bloodyhealth.gitlab.io/-/commit/f8c0f90c1ae9f23bf8e1bc311790b85443149a4d), and adapt the name and link on /index.html [as we did in this commit](https://gitlab.com/bloodyhealth/bloodyhealth.gitlab.io/-/commit2f8850ff5fa78615a4f335b625ea4a67d4acf03a) and [this commit](https://gitlab.com/bloodyhealth/bloodyhealth.gitlab.io/-/commit/f3da9776b1943ffa32458e74ef86eeca98c1891c). Last time I checked it was [here](f3da9776b1943ffa32458e74ef86eeca98c1891c/index.html#L114).
+
+## Communication
+
+You probably want to share the app update by posting on one or more of these platforms:

-##
+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
