+
+#### On the day of the feature freeze
+
+Change the `master` branch to the next MINOR+1 version:
+
+- [ ] Switch to the `master` branch.
+- [ ] Create a new PR branch called `bump_dev_MAJOR_MINOR+1`, eg. `bump_dev_0_22`.
+- [ ] Bump the `bump_dev_MAJOR_MINOR+1` branch to the next development MINOR+1 version.
+  - Change the `Cargo.toml` version value to `MAJOR.MINOR+1.0`.
+  - The commit message should be "Bump version to MAJOR.MINOR+1.0".
+- [ ] Create PR and merge the `bump_dev_MAJOR_MINOR+1` branch to `master`.
+  - Title PR "Bump version to MAJOR.MINOR+1.0".
+
+Create a new release branch:
+
+- [ ] Double check that your local `master` is up-to-date with the upstream repo.
+- [ ] Create a new branch called `release/MAJOR.MINOR+1` from `master`.
+
+Add a release candidate tag, this is optional and only needed for major `bdk-ffi` changes that 
+require a longer testing cycle: 
+
+- [ ] Bump the `release/MAJOR.MINOR+1` branch to `MAJOR.MINOR+1.0-rc.1` version.
+  - Change the `Cargo.toml` version value to `MAJOR.MINOR+1.0-rc.1`.
+  - The commit message should be "Bump version to MAJOR.MINOR+1.0-rc.1".
+- [ ] Add a tag to the `HEAD` commit in the `release/MAJOR.MINOR+1` branch.
+  - The tag name should be `vMAJOR.MINOR+1.0-rc.1`
+  - Use message "Release MAJOR.MINOR+1.0 rc.1".
+  - Make sure the tag is signed, for extra safety use the explicit `--sign` flag.
+- [ ] Push the `release/MAJOR.MINOR` branch and new tag to the `bitcoindevkit/bdk` repo.
+  - Use `git push --tags` option to push the new `vMAJOR.MINOR+1.0-rc.1` tag.
+
+If any issues need to be fixed before the *MAJOR.MINOR+1.0* version is released:
+
+- [ ] Merge fix PRs to the `master` branch.
+- [ ] Git cherry-pick fix commits to the `release/MAJOR.MINOR+1` branch.
+- [ ] Verify fixes in `release/MAJOR.MINOR+1` branch.
+- [ ] Bump the `release/MAJOR.MINOR+1` branch to `MAJOR.MINOR+1.0-rc.x+1` version.
+  - Change the `Cargo.toml` version value to `MAJOR.MINOR+1.0-rc.x+1`.
+  - The commit message should be "Bump version to MAJOR.MINOR+1.0-rc.x+1".
+- [ ] Add a tag to the `HEAD` commit in the `release/MAJOR.MINOR+1` branch.
+  - The tag name should be `vMAJOR.MINOR+1.0-rc.x+1`, where x is the current release candidate number.
+  - Use tag message "Release MAJOR.MINOR+1.0 rc.x+1".
+  - Make sure the tag is signed, for extra safety use the explicit `--sign` flag.
+- [ ] Push the new tag to the `bitcoindevkit/bdk` repo.

+# Development Cycle
+
+This project follows a regular releasing schedule similar to the one [used by the Rust language] 
+except releases always follow the latest [`bdk`] release by one to two weeks.  In short, this means 
+that a new release is made at a regular cadence, with all the feature/bugfixes that made it to 
+`master` in time. This ensures that we don't keep delaying releases waiting for 
+"just one more little thing".
+
+After making a new `bdk-ffi` release tag all downstream language bindings should also be updated.
+
+This project uses [Semantic Versioning], but is currently at MAJOR version zero (0.y.z) meaning it 
+is still in initial development. Anything MAY change at any time. The public API SHOULD NOT be 
+considered stable. Until we reach version `1.0.0` we will do our best to document any breaking API 
+changes in the changelog info attached to each release tag.
+
+We decided to maintain a faster release cycle while the library is still in "beta", i.e. before 
+release `1.0.0`: since we are constantly adding new features and, even more importantly, fixing 
+issues, we want developers to have access to those updates as fast as possible. For this reason we 
+will make a release **every 4 weeks**.
+
+Once the project reaches a more mature state (>= `1.0.0`), we will very likely switch to longer 
+release cycles of **6 weeks**.
+
+The "feature freeze" will happen when [`bdk`] releases a release candidate. This project will then 
+be updated and tested with [`bdk`] release candidates until a final release is published. This 
+means a new branch will be created originating from the `master` tip at that time, and in that 
+branch we will stop adding new features and only focus on ensuring the ones we've added are working 
+properly.
+
+To create a new release a release manager will create a new issue using a `Release` template and 
+follow the template instructions.

+# Integration tests for bdk-ffi
+
+This contains simple tests to make sure bdk-ffi can be used as a dependency for each of the 
+supported bindings languages.
+
+To skip integration tests and only run unit tests use `cargo test --lib`. 
+
+To run all tests including integration tests use `CLASSPATH=./tests/jna/jna-5.8.0.jar cargo test`. 
+
+Before running integration tests you must install the following development tools:
+
+1. [Java](https://openjdk.org/) and [Kotlin](https://kotlinlang.org/), 
+[sdkman](https://sdkman.io/) can help:
+   ```shell
+   sdk install java 11.0.16.1-zulu
+   sdk install kotlin 1.7.20`
+   ```
+   
+2. [Swift](https://www.swift.org/)
+
+3. [Python](https://www.python.org/)
