 ## Building

+To clone this project, use
 
-In order to build, Sparrow requires Java 14 to be installed. The release packages can be built using
+`git clone --recursive git@github.com:sparrowwallet/sparrow.git`
+
+or for those without SSH credentials:
+
+`git clone --recursive https://github.com/sparrowwallet/sparrow.git`
+
+In order to build, Sparrow requires Java 17 or higher to be installed. 
+The release binaries are built with [Eclipse Temurin 18.0.1+10](https://github.com/adoptium/temurin18-binaries/releases/tag/jdk-18.0.1%2B10).
+
+Other packages may also be necessary to build depending on the platform. On Debian/Ubuntu systems:
+
+`sudo apt install -y rpm fakeroot binutils`
+
+
+The Sparrow binaries can be built from source using
 
 `./gradlew jpackage`
 
+Note that to build the Windows installer, you will need to install [WiX](https://github.com/wixtoolset/wix3/releases).
+
+When updating to the latest HEAD
+
+`git pull --recurse-submodules`
+
+The release binaries are reproducible from v1.5.0 onwards (pre codesigning and installer packaging). More detailed [instructions on reproducing the binaries](docs/reproducible.md) are provided.
+
+> Video documentation of your build process uploaded to [bitcoinbinary.org](https://bitcoinbinary.org/) is appreciated. Alternatively check the site if you wish to see if someone else already verified the provided binaries.

+Java 17 or higher must be installed. 
 
 ## Configuration
 
-Sparrow stores it's configuration, log file and wallets in a location appropriate to the operating system:
+Sparrow has a number of command line options, for example to change its home folder or use testnet:
 
-Platform | Location
--------- | --------
-OSX      | ~/.sparrow
-Linux    | ~/.sparrow
-Windows  | %APPDATA%/Sparrow
+```
+./sparrow -h
+
+Usage: sparrow [options]
+  Options:
+    --dir, -d
+      Path to Sparrow home folder
+    --help, -h
+      Show usage
+    --level, -l
+      Set log level
+      Possible Values: [ERROR, WARN, INFO, DEBUG, TRACE]      
+    --network, -n
+      Network to use
+      Possible Values: [mainnet, testnet, regtest, signet]
+```
+
+As a fallback, the network (mainnet, testnet, regtest or signet) can also be set using an environment variable `SPARROW_NETWORK`. For example:
+
+`export SPARROW_NETWORK=testnet`
+
+A final fallback which can be useful when running the Sparrow binary is to create a file called ``network-testnet`` in the Sparrow home folder (see below) to configure the testnet network.
+
+Note that if you are connecting to an Electrum server when using testnet, that server will need to be running on testnet configuration as well.
+
+When not explicitly configured using the command line argument above, Sparrow stores its mainnet config file, log file and wallets in a home folder location appropriate to the operating system:
+
+| Platform | Location |
+|----------| -------- |
+| OSX      | ~/.sparrow |
+| Linux    | ~/.sparrow |
+| Windows  | %APPDATA%/Sparrow |
+
+Testnet, regtest and signet configurations (along with their wallets) are stored in subfolders to allow easy switching between networks.

+# Reproducible builds
+
+Reproducibility is a goal of the Sparrow Wallet project.
+As of v1.5.0 and later, it is possible to recreate the exact binaries in the Github releases (specifically, the contents of the `.tar.gz` and `.zip` files).
+
+Due to minor variances, it is not yet possible to reproduce the installer packages (`.deb`, `.rpm` and `.exe`).
+In addition, the OSX binary is code signed and thus can't be directly reproduced yet.
+Work on resolving both of these issues is ongoing.
+
+## Reproducing a release
+
+### Install Java
+
+Because Sparrow bundles a Java runtime in the release binaries, it is essential to have the same version of Java installed when creating the release.
+For v1.6.6 and later, this is Eclipse Temurin 18.0.1+10.
+
+#### Java from Adoptium github repo
+
+It is available for all supported platforms from [Eclipse Temurin 18.0.1+10](https://github.com/adoptium/temurin18-binaries/releases/tag/jdk-18.0.1%2B10).
+
+For reference, the downloads are as follows:
+- [Linux x64](https://github.com/adoptium/temurin18-binaries/releases/download/jdk-18.0.1%2B10/OpenJDK18U-jdk_x64_linux_hotspot_18.0.1_10.tar.gz)
+- [MacOS x64](https://github.com/adoptium/temurin18-binaries/releases/download/jdk-18.0.1%2B10/OpenJDK18U-jdk_x64_mac_hotspot_18.0.1_10.tar.gz)
+- [MacOS aarch64](https://github.com/adoptium/temurin18-binaries/releases/download/jdk-18.0.1%2B10/OpenJDK18U-jdk_aarch64_mac_hotspot_18.0.1_10.tar.gz)
+- [Windows x64](https://github.com/adoptium/temurin18-binaries/releases/download/jdk-18.0.1%2B10/OpenJDK18U-jdk_x64_windows_hotspot_18.0.1_10.zip)
+
+#### Java from Adoptium deb repo
+
+It is also possible to install via a package manager on *nix systems. For example, on Debian/Ubuntu systems:
+
+- Install dependencies:
+```sh
+sudo apt-get install -y wget curl apt-transport-https gnupg
+```
+
+Download Adoptium public PGP key:
+```sh
+curl --tlsv1.2 --proto =https --location -o adoptium.asc https://packages.adoptium.net/artifactory/api/gpg/key/public
+```
+
+Check if key fingerprint matches: `3B04D753C9050D9A5D343F39843C48A565F8F04B`:
+```
+gpg --import --import-options show-only adoptium.asc
+```
+If key doesn't match, do not procede.
+
+Add Adoptium PGP key to a the keyring shared folder:
+```sh
+sudo cp adoptium.asc /usr/share/keyrings/
+```
+
+Add Adoptium debian repository:
+```sh
+echo "deb [signed-by=/usr/share/keyrings/adoptium.asc] https://packages.adoptium.net/artifactory/deb $(awk -F= '/^VERSION_CODENAME/{print$2}' /etc/os-release) main" | sudo tee /etc/apt/sources.list.d/adoptium.list
+```
+
+Update cache, install the desired temurin version and configure java to be linked to this same version:
+```
+sudo apt update -y
+sudo apt-get install -y temurin-18-jdk=18.0.1+10
+sudo update-alternatives --config java
+```
+
+#### Java from SDK
+
+A alternative option for all platforms is to use the [sdkman.io](https://sdkman.io/) package manager ([Git Bash for Windows](https://git-scm.com/download/win) is a good choice on that platform).
+See the installation [instructions here](https://sdkman.io/install).
+Once installed, run
+```shell
+sdk install java 18.0.1-tem
+```
+
+### Other requirements
+
+Other packages may also be necessary to build depending on the platform. On Debian/Ubuntu systems:
+```shell
+sudo apt install -y rpm fakeroot binutils
+```
+
+### Building the binaries
+
+The project can cloned for a specific release tag as follows:
+```shell
+GIT_TAG="1.7.0"
+git clone --recursive --branch "${GIT_TAG}" https://github.com/sparrowwallet/sparrow.git
+```
+
+Thereafter, building should be straightforward:
+
+```shell
+cd sparrow
+./gradlew jpackage
+```
+
+The binaries (and installers) will be placed in the `build/jpackage` folder.
+
+### Verifying the binaries are identical
+
+Verify the built binaries against the released binaries on https://github.com/sparrowwallet/sparrow/releases.
+
+Note that you will be verifying the files in the `build/jpackage/Sparrow` folder against either the `.tar.gz` or `.zip` releases.
+Download either of these depending on your platform and extract the contents to a folder (in the following example, `/tmp`).
+Then compare all of the folders and files recursively:
+
+```shell
+diff -r build/jpackage/Sparrow /tmp/Sparrow
+```
+
+This command should have no output indicating that the two folders (and all their contents) are identical.
+
+If there is output, please open an issue with detailed instructions to reproduce, including build system platform.

+#
+#   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.
