+
+Zsh is almost best shell nowadays, because it has oh-my-zsh :). You can configure a theme, add useful plugins, such as zsh-syntax-highlighting and zsh-autosuggestions.
+
+Here's a simple progress of installing zsh and configuring it.
+
+## Step 1: Install Zsh
+
+### On Ubuntu/Debian
+```bash
+sudo apt install zsh wget git -y
+```
+
+### On macOS
+```bash
+brew install zsh wget git
+```
+
+After installation, set Zsh as your default shell(or not, it will automatically change to zsh while installing oh-my-zsh):
+```bash
+chsh -s $(which zsh)
+```
+
+Log out and log back in for the changes to take effect.
+
+## Step 2: Install Oh-My-Zsh
+
+Install Oh-My-Zsh using wget:
+
+```bash
+# Using wget
+sh -c "$(wget -O- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
+```
+
+## Step 3: Configure the 'ys' Theme
+
+Edit your Zsh configuration file:
+```bash
+ZSH_THEME="ys"
+```
+
+## Step 4: Install Plugins
+
+### Install zsh-syntax-highlighting
+```bash
+git clone https://github.com/zsh-users/zsh-syntax-highlighting.git $ZSH_CUSTOM/plugins/zsh-syntax-highlighting
+```
+
+### Install zsh-autosuggestions
+```bash
+git clone https://github.com/zsh-users/zsh-autosuggestions.git $ZSH_CUSTOM/plugins/zsh-autosuggestions
+```
+
+## Step 5: Enable Plugins
+
+Edit your Zsh configuration again:
+```bash
+plugins=(git zsh-syntax-highlighting zsh-autosuggestions)
+```
+
+Save and exit.
+
+## Step 6: Apply Changes
+
+Reload your Zsh configuration:
+```bash
+source ~/.zshrc
+# or
+exec zsh
+```
+
+## Step 7: Verify Installation
+
+Check that everything is working:
+```bash
+# Check Zsh version
+zsh --version
+
+# Check Oh-My-Zsh
+omz version
+
+# Verify plugins are working (should see colored syntax and suggestions)
+echo "This should show syntax highlighting"  # Type slowly to see suggestions
+```
+
+## Complete Installation Scripts
+
+### For Ubuntu/Debian
+```bash
+sudo apt install zsh wget git -y
+sh -c "$(wget -O- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
+sed -i 's/robbyrussell/ys/' ~/.zshrc
+git clone https://github.com/zsh-users/zsh-syntax-highlighting.git $ZSH_CUSTOM/plugins/zsh-syntax-highlighting
+sed -i 's/^plugins=(/plugins=(zsh-syntax-highlighting /' ~/.zshrc
+git clone https://github.com/zsh-users/zsh-autosuggestions.git $ZSH_CUSTOM/plugins/zsh-autosuggestions
+sed -i 's/^plugins=(/plugins=(zsh-autosuggestions /' ~/.zshrc
+```
+
+### For macOS

+brew install zsh wget git
+sh -c "$(wget -O- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

+git clone https://github.com/zsh-users/zsh-syntax-highlighting.git $ZSH_CUSTOM/plugins/zsh-syntax-highlighting
+sed -i "" 's/^plugins=(/plugins=(zsh-syntax-highlighting /' ~/.zshrc
+git clone https://github.com/zsh-users/zsh-autosuggestions.git $ZSH_CUSTOM/plugins/zsh-autosuggestions
