+
+
+## Setting up the development environment
+
+If you haven't setup your development environment. Let's go through a small step-by-step tutorial to get started with your Docusaurus project.
+
+:::note
+Feel free to edit this page as you follow the tutorial!
+:::
+
+### Step 1:  Generate a Docusaurus site
+
+Let's run a command to generate the classic template. You can run this command anywhere either in a new empty repository or within an existing repository.
+
+```shell
+npx @docusaurus/init@latest init my-documentation classic
+```
+
+### Step 2: Install Dependencies
+
+Don't forget to install the dependencies required, run the install command from your preferred package manager in the root directory of the project:
+
+<Tabs
+    defaultValue="npm"
+    values={[
+        { label: 'npm', value: 'npm' },
+        { label: 'Yarn', value: 'yarn' },
+    ]}
+>
+<TabItem value="npm">
+
+```shell
+npm install
+```
+
+</TabItem>
+<TabItem value="yarn">
+
+```shell
+yarn 
+```
+
+</TabItem>
+</Tabs>
+
+### Step 3: Start your Docusaurus site
+
+Run this command to start the Docusaurus development server and start developing by adding content to your docusaurus project: 
+
+```shell
+npx docusaurus start
+```
+
+Open up `gettingStarted.md` in your project folder and try to edit some lines. The site should reload automatically after you save your changes.
+
+### That's it!
+
+Congratulations! You've successfully run and modified your Docusaurus project.
