    ### Move and/or copy files into expected directories
    This depends on your preferences, but this is how I decided to finalize my install:
    Move the executable to `/usr/local/bin`:
    Move `$GOPATH/src/github.com/DataDog/datadog-agent/` into `/opt/` (to be compatible with normal package distributions).
    ```shell
    cd $GOPATH/src/github.com/DataDog/datadog-agent/bin/agent/dist
    mv ./bin/agent/agent /usr/local/bin/datadog-agent
    cd $GOPATH/src/github.com/DataDog/
    mv datadog-agent /opt/
    ```
    Copy the config files into `/etc/datadog-agent` and edit as necessary:
    ```shell
    mkdir -p /etc/datadog-agent/
    cd $GOPATH/src/github.com/DataDog/datadog-agent/bin/agent/dist
    cd /opt/datadog-agent/bin/agent/dist
    cp -r . /etc/datadog-agent/
    ```
    Edit `/etc/datadog-agent/datadog.yaml` to add your API key.
    #### Start the agent:
    ```shell
    datadog-agent start -c /etc/datadog-agent/datadog.yaml
    ### Post-install
    ### Configure a user:
    I didn't need to do this part since I have a specific user/group setup for my development machines, but this is to illustrate how you might.
    This is similar to how it's done in the [Dockerfile](https://github.com/DataDog/datadog-agent/blob/master/Dockerfiles/agent/Dockerfile).
    The difference here is that I didn't add it to the root group, but you can choose to do what you'd like.
    ```
    # create user if it does not yet exist
    adduser --system --no-create-home --disabled-password --ingroup dd-agent dd-agent
    # Give permissions to relevant directories
    chown -R dd-agent:dd-agent /etc/datadog-agent/ /opt/datadog-agent/ /var/log/datadog/
    chmod g+r,g+w,g+X -R /etc/datadog-agent/ /var/log/datadog/
    ```
    (To add `dd-agent` to the root group, you can do the following instead of the above `adduser` command, then `chown` accordingly):
    ```
    adduser --system --no-create-home --disabled-password --ingroup root dd-agent
    chown -R dd-agent:root /etc/datadog-agent/ /opt/datadog-agent/ /var/log/datadog/
    ```
    With guidance from [this file](https://github.com/DataDog/datadog-agent/blob/master/omnibus/config/templates/datadog-puppy/systemd.service.erb), here's the systemd service for the puppy agent:
    ```
    root@pxpi:~# cat /lib/systemd/system/datadog-agent.service
    [Unit]
    Description="Datadog Agent"
    After=network.target
    [Service]
    Type=simple
    PIDFile=/opt/datadog-agent/run/agent.pid
    User=dd-agent

    ExecStart=/opt/datadog-agent/bin/agent/agent start -p /opt/datadog-agent/run/agent.pid
    [Install]
    WantedBy=multi-user.target
    ```
    For more post-install steps on Debian-ish systems, you can also take a look at the [omnibus postinstall script in the datadog agent repo](https://github.com/DataDog/datadog-agent/blob/master/omnibus/package-scripts/agent/postinst).

    # 1. Install Go (Golang): without GVM

    **Note: I haven't tried gvm, but the corresponding guide is here: [https://github.com/tgogos/rpi_golang#2-with-go-version-manager-gvm](https://github.com/tgogos/rpi_golang#2-with-go-version-manager-gvm). The rest of this guide will show how to install Go without GVM.**

    Note: This is from [this fork](https://github.com/btamayo/rpi_golang) of [tgogos/rpi_golang](https://github.com/tgogos/rpi_golang), which has instructions on how to install Go version 1.10.3.

    ### Quick Summary:

    1. Use the pre-built binary in the repo to install Go 1.4.3
    2. Optionally use Go 1.4.3 to upgrade (build) Go 1.10.3



    **This presumes you're the root user**. If you are not, you may need to append `sudo` to some of the following commands.

    Optionally, ensure that the following directories do not exist as they _may_ conflict with the process.

    - `/usr/local/go`
    - `$HOME/go1.4`

    ## 1. Clone the repo:
    ```shell
    git clone https://github.com/tgogos/rpi_golang.git
    cd rpi_golang/
    ```

    ## 2. Install either only 1.4.3 or upgrade to 1.10.3:

    ### For 1.4.3 only:
    If you have no intention of upgrading to 1.10.3, you can untar the binary in the repo into `/usr/local`.
    ```shell
    # untar into /usr/local
    tar -xzf go1.4.3.linux-armv7.tar.gz -C /usr/local

    # Add to shell and .bashrc
    export PATH=/usr/local/go/bin:$PATH
    echo "export PATH=/usr/local/go/bin:$PATH" >> $HOME/.bashrc

    # go version should now output something
    go version

    # If you're happy with 1.4, you can stop at this point.
    ```

    You're done!

    ### For 1.10.3:

    If you would like to upgrade to 1.10.3, follow this to untar the binary from the repo into a different location, and use it to bootstrap the build:

    Run `rm -rf /usr/local/go` if you accidentally made this directory already.

    ```shell
    # We use the 1.4 binary in the repo to bootstrap building 1.10:
    # While still in rpi_golang directory, make the alternate directory:
    mkdir -p $HOME/go1.4

    # Untar into that directory
    tar -xzf go1.4.3.linux-armv7.tar.gz -C $HOME/go1.4 --strip-components=1

    # Download and untar the 1.10.3 src into /usr/local
    wget https://dl.google.com/go/go1.10.3.src.tar.gz
    tar -xz -C /usr/local -f go1.10.3.src.tar.gz
    ```

    #### Build 1.10.3:

    ```shell
    cd /usr/local/go/src

    time GOROOT_BOOTSTRAP=$HOME/go1.4 ./make.bash
    ```

    #### Output:

    A successful output will look something like:

    ```shell
    root@rpi:/usr/local/go/src# time GOROOT_BOOTSTRAP=$HOME/go1.4 ./make.bash

    Building Go cmd/dist using /root/go1.4.
    Building Go toolchain1 using /root/go1.4.
    Building Go bootstrap cmd/go (go_bootstrap) using Go toolchain1.
    Building Go toolchain2 using go_bootstrap and Go toolchain1.
    Building Go toolchain3 using go_bootstrap and Go toolchain2.
