-   **IMPORTANT:** First run takes 30-60 minutes as it builds for all architectures (armeabi-v7a, arm64-v8a, x86, x86_64).

 - Debug APKs: `build/outputs/apk/gplay/debug/` and `build/outputs/apk/fat/debug/`
 - Release APKs require signing configuration in `~/.gradle/gradle.properties`
 
-### Common Build Issues
-
-1. **Missing NDK or incorrect version:**
-   - Error: `ANDROID_NDK_ROOT not set` or native library missing
-   - Solution: Install NDK 27.0.12077973 and set ANDROID_NDK_ROOT environment variable
-
-2. **Submodules not initialized:**
-   - Error: Missing deltachat-core-rust files
-   - Solution: Run `git submodule update --init --recursive`
-
-3. **Gradle wrapper validation:**
-   - Always validate gradle wrapper before building: `./gradlew wrapper --gradle-version=current`
-   - Wrapper is validated in CI via `gradle/actions/wrapper-validation@v4`
-
-4. **Clean build issues:**
-   - If build fails, try: `./gradlew clean && scripts/ndk-make.sh && ./gradlew assembleDebug`

-### When to Rebuild Native Libraries
-
-Rebuild native libraries (`scripts/ndk-make.sh`) when:
-- Updating deltachat-core-rust submodule
-- Modifying anything in `jni/` directory
-- Changing NDK version
-- After `git clean -fdx` or fresh clone
-
-**DO NOT** rebuild native libraries for:
-- Pure Java/Kotlin code changes
-- Resource file changes
-- Gradle configuration changes (unless changing native library linking)
-- Documentation updates

-## CI/CD Workflows
-
-### Preview APK Workflow (.github/workflows/preview-apk.yml)
-
-Runs on every pull request to build and upload a preview APK:
-
-1. **Setup steps:**
-   - Checks out repository with submodules
-   - Validates Fastlane metadata
-   - Sets up Rust cache (working-directory: jni/deltachat-core-rust)
-   - Sets up Java 17 (Temurin distribution)
-   - Sets up Android SDK
-   - Caches Gradle dependencies
-   - Sets up NDK r27
-
-2. **Build process:**
-   ```bash
-   scripts/install-toolchains.sh && scripts/ndk-make.sh armeabi-v7a
-   ./gradlew --no-daemon -PABI_FILTER=armeabi-v7a assembleFossDebug
-   ```
-   Note: Builds only armeabi-v7a for faster CI builds
-
-3. **Output:** Uploads APK artifact to GitHub Actions
-
-### Important CI Considerations
-
-- Always validate Gradle wrapper before committing changes
-- Fastlane metadata must be valid (validated in CI)
-- Use `--no-daemon` flag for Gradle in CI environments
-- CI builds use FOSS flavor to avoid Google Services dependencies
-- Expected CI build time: 15-25 minutes for full workflow

 ### Coding Conventions
 
-Project language is Java.
+Source files are partly derived from different other open source projects
+and may follow different coding styles and conventions.
 
-Code formatting is enforced via [Spotless](https://github.com/diffplug/spotless) Gradle plugin.
-Auto-format all files by running `./gradlew spotlessApply` before opening a PR.
-CI will fail if files are not formatted correctly so make sure to run the formatter before pushing.
+If you do a PR fixing a bug or adding a feature,
+please embrace the coding convention you see in the corresponding files,
+so that the result fits well together.
 
-If you do a PR fixing a bug or adding a feature, do not refactor or rename things in the same PR
+Do not refactor or rename things in the same PR
 to make the diff small and the PR easy to review.
 
+Project language is Java.

 By using [Delta Chat Core](https://github.com/deltachat/deltachat-core-rust)
 there is already a strong separation between "UI" and "Model".
 Further separations and abstraction layers are often not helpful

Należy pamiętać, że mechanizm Forward Secrecy zwiększa bezpieczeństwo tylko w przypadku usuwania wiadomości.

+    <p>The <a href="https://nlnet.nl/">NLnet foundation</a> granted in 2019/2020 EUR 46K for
+completing Rust/Python bindings and instigating a Chat-bot eco-system.</p>
+  </li>
+  <li>
+    <p>In 2021 we received further EU funding for two Next-Generation-Internet
+proposals, namely for <a href="https://dapsi.ngi.eu/hall-of-fame/eppd/">EPPD - email provider portability directory</a> (~97K EUR) and <a href="https://nlnet.nl/project/EmailPorting/">AEAP - email address porting</a> (~90K EUR) which resulted in better multi-profile support, improved QR-code contact and group setups and many networking improvements on all platforms.</p>
+  </li>
+  <li>
+    <p>From End 2021 till March 2023 we received <em>Internet Freedom</em> funding (500K USD) from the
+U.S. Bureau of Democracy, Human Rights and Labor (DRL). 
+This funding supported our long-running goals to make Delta Chat more usable 
+and compatible with a wide range of email servers world-wide, and more resilient and secure
+in places often affected by internet censorship and shutdowns.</p>
+  </li>
+  <li>
+    <p>2023-2024 we successfully completed the OTF-funded 
+<a href="https://www.opentech.fund/projects-we-support/supported-projects/secure-chat-mail-with-delta-chat/">Secure Chatmail project</a>, 
+allowing us to introduce guaranteed encryption, 
+creating a <a href="https://delta.chat/chatmail">chatmail server network</a> 
+and providing “instant onboarding” in all apps released from April 2024 on.</p>
+  </li>
+  <li>
+    <p>In 2023 and 2024 we got accepted in the Next Generation Internet (NGI)
+program for our work in <a href="https://nlnet.nl/project/WebXDC-Push/">webxdc PUSH</a>,
+along with collaboration partners working on 
+<a href="https://nlnet.nl/project/Webxdc-Evolve/">webxdc evolve</a>,

+All of these projects are partially completed or to be completed in early 2025.</p>

 <p>Delta Chat наразі не підтримує ідеальну пряму секретність (Perfect Forward Secrecy, PFS). Це означає, що якщо ваш приватний ключ для розшифрування буде скомпрометовано, а хтось заздалегідь зібрав ваші повідомлення під час передачі, він зможе розшифрувати та прочитати їх, використовуючи зламаний ключ. Зверніть увагу, що пряма секретність підвищує рівень безпеки лише в тому разі, якщо ви видаляєте повідомлення. Інакше, якщо хтось отримує доступ до ваших ключів розшифрування, він зазвичай також має доступ до всіх ваших невидалених повідомлень і навіть не потребує розшифровувати заздалегідь перехоплені дані.</p>
