 ## Development Environment Setup
 
-(TODO) **Explain how to set up a development environment**
+### Prerequisites
+- Go (Golang): The latest version of Go, as the project is written in this language. Go's installation guide can be found at https://golang.org/doc/install.
+- Git: Version control system for cloning the repository and managing code changes. Installation instructions are available at https://git-scm.com/book/en/v2/Getting-Started-Installing-Git.
+
+
+### Setting up the project
+
+1. Clone the Repository: Clone the KitOps source code to your local machine:
+
+```shell
+git clone https://github.com/jozu-ai/kitops.git
+cd kitops
+```
+
+2. Install Go Dependencies: Inside the project directory, fetch and install the project's dependencies using the Go command:
+
+```shell
+go mod tidy
+```
+
+3. Build the Kit CLI: Compile the source code into an executable named kit:
+```shell
+go build -o kit
+```
+
+4. Run Your Build: Execute the built CLI to see all available commands:
+
+```shell
+go run .
+```
+5. Updating Dependencies: If you add or update dependencies, ensure to update the go.mod and go.sum files by running `go mod tidy` again and include these changes in your commits.
