+# CSDE
+
+The CorDapp Standard Development Environment (CSDE) makes the process of prototyping CorDapps more straight-forward. The CSDE is obtained by cloning our `CSDE-cordapp-template-kotlin` or `CSDE-cordapp-template-java` repository to your local machine. The CSDE provides:
+
+- a prepared CorDapp project that you can use as a starting point to develop your own prototypes.
+- a base Gradle configuration that brings in the dependencies you need to write and test a Corda 5 CorDapp.
+- a set of Gradle helper tasks which speed up and simplify the development and deployment process; these are effectively wrappers over the [Corda CLI](https://docs.r3.com/en/platform/corda/5.0/developing-applications/tooling/installing-corda-cli.html).
+- debug configuration for debugging a local Corda cluster.
+- the `MyFirstFlow` code which forms the basis of the Getting Started documentation.
+- the `utxoexample` Chat CorDapp, which provides a basic, working [UTXO](https://docs.r3.com/en/platform/corda/5.0/introduction/glossary.html#utxo) Ledger CorDapp.
+- the ability to configure the members of the local Corda network.
+
+
+## Installation 
+
+### Prerequisites
+
+Be sure to [install](https://docs.r3.com/en/platform/corda/5.0/developing-applications/getting-started/prerequisites.html) required SW and CLI tools prior starting development with CSDE.
+
+## Template project
+
+Template Java or Kotlin projects are availvable as a git repo.
+
+```sh
+git clone https://github.com/corda/CSDE-cordapp-template-java.git <local-folder>
+..
+git checkout release/corda-5-0
+git init
+git remote add origin <remote-url>
+```
+
+In order for the `CSDE-cordapp-template` app to work on MacOS with VsCode, these steps must be made:
+
+### Add `$rootDir` prefix in `build.gradle`
+
+For some reason, to run gradle tasks from VsCode, the default `build.gradle` must be updated with absolute paths. Unpatched file works just fine for commands from CLI.
+
+*`build.gradle`*
+```diff
+    // Configure the CSDE
+    csde {
+        cordaClusterURL = "https://localhost:8888"
+-       networkConfigFile = "config/static-network-config.json"
++       networkConfigFile = "$rootDir/config/static-network-config.json"
+        r3RootCertFile = "config/r3-ca-key.pem"
+        corDappCpiName = "MyCorDapp"
+        notaryCpiName = "NotaryServer"
+        cordaRpcUser = "admin"
+        cordaRpcPasswd ="admin"
+        workflowsModuleName = workflowsModule
+-       csdeWorkspaceDir = "workspace"
++       csdeWorkspaceDir = "$rootDir/workspace"
+        notaryVersion = cordaNotaryPluginsVersion
+        combinedWorkerVersion = combinedWorkerJarVersion
+        postgresJdbcVersion = "42.4.3"
+        cordaDbContainerName = "CSDEpostgresql"
+        cordaBinDir = "${System.getProperty("user.home")}/.corda/corda5"
+        cordaCliBinDir = "${System.getProperty("user.home")}/.corda/cli" 
+    }
+```
+
+Note, that there must be no prefix for `r3RootCertFile` property.
+
+### JDK
+
+[Install](https://docs.azul.com/core/zulu-openjdk/install/macos) recommend JDK (Azul Zulu 11) and tell gradle to use it.
+
+_`gradle.properties`_
+```diff
++ # Use JDK Zulu 11
++ org.gradle.java.home=/Library/Java/JavaVirtualMachines/zulu-11.jdk/Contents/Home
+```
+
+Otherwise, funny errors might happen:
+
+```bash
+oxbee@MacBook HelloCorda % ./gradlew 5-vNodesSetup
+Starting a Gradle Daemon, 1 busy and 3 incompatible and 2 stopped Daemons could not be reused, use --status for details
+
+> Task :1-createGroupPolicy FAILED
+Group policy up to date.
+
+FAILURE: Build failed with an exception.
+
+* What went wrong:
+Execution failed for task ':1-createGroupPolicy'.
+> net.corda.plugins.csde.CsdeException: Unable to find the Corda CLI, has it been installed?
+```
+
+Even if CordaCLI is actually installed! 
+#### List all the Java versions installed on Mac
+
+```shell
+ /usr/libexec/java_home -V
+```
+
+## Execution
+
+		Gradle commands shall be accessible to you at this moment. Although, it is possible to run gradle tasks in VsCode, it is **suggested to execute them as a generic bash commands**, since most of the configuration files are tested and finetuned only for JetBrains IDEA.
+
+Type `./gradlew tasks` to get list of availvable tasks. The most basic of which are:
+
+### Start local Corda application network
+
+```sh
+./gradlew startCord
+```
+
+> [!note] Be sure to have your Docker demon up and running 
+
+### Run virtual nodes
+
+```sh
+./gradlew 5-vNodesSetup
+```
