 Due to minor variances, it is not yet possible to reproduce the installer packages (`.deb`, `.rpm` and `.exe`).

+#### Java from Adoptium deb repo
 
 It is also possible to install via a package manager on *nix systems. For example, on Debian/Ubuntu systems:
-```shell
-sudo apt-get install -y wget apt-transport-https gnupg
-wget https://adoptopenjdk.jfrog.io/adoptopenjdk/api/gpg/key/public
-gpg --no-default-keyring --keyring ./adoptopenjdk-keyring.gpg --import public
-gpg --no-default-keyring --keyring ./adoptopenjdk-keyring.gpg --export --output adoptopenjdk-archive-keyring.gpg
-rm adoptopenjdk-keyring.gpg
-sudo mv adoptopenjdk-archive-keyring.gpg /usr/share/keyrings
-echo "deb [signed-by=/usr/share/keyrings/adoptopenjdk-archive-keyring.gpg] https://adoptopenjdk.jfrog.io/adoptopenjdk/deb $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/adoptopenjdk.list
-sudo apt update -y
-sudo apt-get install -y adoptopenjdk-16-hotspot=16.0.1+9-3
+
+- 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 16.0.1.hs-adpt
+sdk install java 18.0.1-tem
 ```
 
-#### Other requirements
+### 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
+### Building the binaries
 
 The project can cloned for a specific release tag as follows:
 ```shell
-GIT_TAG="1.5.2"
-git clone --recursive --branch "${GIT_TAG}" git@github.com:sparrowwallet/sparrow.git

-##
+#
+#   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
