feat: Add setup script (#1)

* feat: Add setup.sh with outline of needed steps

* feat: Add distrobox commands

* feat: Enable creation of desktop launcher

* docs: Revamp setup instructions

* docs: Clarify option 1 instructions more

* docs: Fix script use command

On my main system, `./setup.sh DaVinci_Resolve_version_Linux.run` works
fine, but not on other systems I tested on. Adding `./` in front of the
argument works around this

* fix: Create /opt/resolve for app launcher

* fix: mkdir before distrobox-export

 You will also need the latest release of DaVinci Resolve from [Blackmagic's website](https://www.blackmagicdesign.com/products/davinciresolve)
 
-## Setup
+Finally, I recommend that you download the `setup.sh` script from this repository to simplify the setup process.
 
-The long-term plan is to automate this process with a setup script or app, but for now, follow the instructions below to get DaVinci Resolve up and running on your system.
+## Easy Setup
+
+This assumes you're using the `setup.sh` script from this repository.
+
+First, you need to make `setup.sh` executable.
+
+### Option 1
+
+Open a terminal, then run `chmod +x /path/to/setup.sh`
+
+Then, `/path/to/setup.sh /path/to/DaVinci_Resolve_versionnumber_Linux.run`
+
+### Option 2
+
+If you're more comfortable in a GUI:
+
+If you're using GNOME, open Files and navigate to where you downloaded the script to. In the example below, the script is in the same folder that I extracted the DaVinci Resolve download to. I recommend you do the same for ease of use, as the rest of the instructions will assume you have done so.

+
+Right-click, and select Properties.
+
+![](screenshots/setup_02.webp)
+
+Then, make sure "Executable as Program" is toggled on.
+
+![](screenshots/setup_03.webp)
+
+Right-click on an empty spot in the folder. You should see either "Open in Console" as in the screenshot, or "Open in Terminal." Either will be fine.
+
+![](screenshots/setup_04.webp)
+
+In the newly-opened terminal window, enter the command below. Replace 'version' with the version of DaVinci Resolve that you are installing (see screenshot for example):
+
+```
+./setup.sh ./DaVinci_Resolve_version_Linux.run
+```
+
+![](screenshots/setup_05.webp)
+
+Then, follow any further prompts in the installation script.
+
+## Manual Setup
 
 First, download DaVinci Resolve from the link above. Then, extract the archive. Open a terminal in the directory that contains the `DaVinci_Resolve_<version>_Linux.run` file (\<version\> will correspond to the version of DaVinci Resolve you downloaded).
