-# Install and Configure the CLI
+### Install and Configure the CLI
+
+The primary method for interacting with the SD2E platform is the Agave command
+line interface (CLI). The CLI is a collection of ~150 shell scripts for managing
+authorization, files, systems, jobs, and more. 
+
+There are three methods to install the CLI:
+1. Run an installer script to install in ~/sd2e-cloud-cli/bin/
+2. Manual install to a location of your choosing
+3. Pull a CLI Docker image
+
+#### 1. Run an installer script to install in ~/sd2e-cloud-cli/bin/
+
+Open a terminal window and perform the following:
+
+```
+# Run the installer
+% curl -L https://raw.githubusercontent.com/sd2e/sd2e-cli/master/install/install.sh | sh
+
+# Source your .bashrc
+% source ~/.bashrc
+
+# Verify the CLI is installed
+% sd2e info
+
+DARPA SD2E version 1.0.1
+TACC Cloud API tenant: sd2e
+TACC Cloud API versions:
+        Science APIs: 2.2.5
+        Reactors API: dev
+        TACC Accounting API: v1
+```
+
+#### 2. Manual install to a location of your choosing
+
+Open a terminal window and perform the following:
+
+```
+# Navigate to a location of your choosing
+% mkdir sd2e-project && cd sd2e-project
+
+# Download and unpack the CLI
+% curl -L https://raw.githubusercontent.com/sd2e/sd2e-cli/master/sd2e-cloud-cli.tgz -o sd2e-cloud-cli.tgz
+% tar -xvzf sd2e-cloud-cli.tgz
+
+# Add the CLI executables to your $PATH
+% echo "PATH=\$PATH:$PWD/sd2e-cloud-cli/bin" >> ~/.bashrc
+% source ~/.bashrc
+
+# Verify the CLI is installed
+% sd2e info
+
+DARPA SD2E version 1.0.1
+TACC Cloud API tenant: sd2e
+TACC Cloud API versions:
+	Science APIs: 2.2.5
+	Reactors API: dev
+```
+
+#### 3. Pull a CLI Docker image
+
+```
+# Pull the latest image
+% docker pull sd2e/cloud-cli:latest
+% docker run -it -v $HOME/.agave:/root/.agave sd2e/cloud-cli bash
+```
