+# GRDB + SQLCipher 
+
+## What is this?
+This is a fork of [GRDB](https://github.com/groue/GRDB.swift) which contains a [SQLCipher Community Edition](https://www.zetetic.net/sqlcipher/open-source/) amalgamation packaged so that it can be consumed as a Swift Package.
+
+The default branch for this repository is `SQLCipher` so that we can more easily pull upstream changes if we need to.
+
+## Versioning
+
+* This Package: *2.0.0*
+* GRDB: *6.0.0*
+* SQLCipher: *4.5.3*
+
+## Contributions
+We do not accept contributions to this repository at this time.  However, feel free to open an issue in order to start a discussion.
+
+## We are hiring!
+DuckDuckGo is growing fast and we continue to expand our fully distributed team. We embrace diverse perspectives, and seek out passionate, self-motivated people, committed to our shared vision of raising the standard of trust online. If you are a senior software engineer capable in either iOS or Android, visit our [careers](https://duckduckgo.com/hiring/#open) page to find out more about our openings!
+
+## Updating from Upstream
+
+Add remote upstream:
+
+* `git remote add upstream [email protected]:groue/GRDB.swift.git`
+
+Check out upstream's master branch locally:
+
+* `git fetch upstream +master:upstream-master && git checkout upstream-master`
+
+Update upstream's master branch if needed:
+
+* `git pull upstream master`
+
+Switch back to the `SQLCipher` branch and merge with upstream-master:
+
+* `git merge upstream-master`
+
+Resolve any conflicts that may occur (normally there should be none or only in Package.swift)
+and commit the merge. Once done, run `prepare_release.sh` script to fetch and compile the latest tag
+of SQLCipher and embed it in GRDB.swift:
+
+* `./prepare_release.sh`
+
+The script will also:
+* present the summary of updated versions and ask you to pick the new version number for DuckDuckGo GRDB fork,
+* test the build,
+* create a new release branch and commit changes.
+
+For versioning, follow [Semantic Versioning Rules](https://semver.org), but note you don't need
+to use the same version as GRDB. Examples:
+
+* Upstream GRDB 5.6.0, after merge -> 5.12.0
+  * This project 1.0.0 -> 1.1.0
+
+* Upstream GRDB 5.12.0, after merge -> 6.0.0
+  * This project 1.1.0 -> 2.0.0
+
+If everything looks fine:
+* push your branch,
+* create PR for BSK referencing the new branch,
+* create PRs for iOS and macOS apps referencing your BSK branch.
+
+Once approved:
+* merge your branch back to `SQLCipher`,
+* create a tag matching the release number **without the 'v' prefix** (those are reserved for upstream),
+* push the tag,
+* update the reference to GRDB in BSK to point to a tag.
+
+### Compiling SQLCipher manually
+
+In case `prepare_release.sh` script fails, you need to compile SQLCipher amalgamation package
+manually. See [general instructions](https://github.com/sqlcipher/sqlcipher#compiling-for-unix-like-systems):
+
+* Use `./configure --with-crypto-lib=none`.
+* Remember to use `make sqlite3.c` and not `make`.
+* Copy `sqlite3.c` and `sqlite3.h` to `Sources/SQLCipher/sqlite3.c` and `Sources/SQLCipher/include/sqlite3.h`.
