## Installation
1. [Download and install Julia](https://julialang.org/downloads/platform/)
2. Open a new Julia window and type the `]` key
3. Type `add XLSX Gtk` and press **Enter**
Alternatively, you can run the [install
script](https://github.com/MillironX/beefblup/raw/master/Julia/install.jl) from
Julia.
2. Download the [beefblup ZIP
file](https://github.com/MillironX/beefblup/archive/refs/tags/v0.2.zip) and unzip it someplace memorable
3. In your file explorer, copy the address of the "beefblup" folder
4. Launch Julia
5. Type `cd("<the address copied in step 5")` and press **Enter** (For example,
`cd("C:\Users\MillironX\Documents\beefblup")`)
6. Type the `]` key
7. Type `activate .` and press **Enter**
8. Type `instantiate` and press **Enter**
9. Installation is done: you can close the Julia window
## How to Use
> **Note:** beefblup and [Juno](https://junolab.org)/[Julia Pro](https://juliacomputing.com/products/juliapro.html) currently [don't get along](https://github.com/JunoLab/Juno.jl/issues/118).
> Although it's tempting to just open up beefblup in Juno and press the big play
> button, it won't work. Follow these instructions until it's fixed. If you

1. Download the [beefblup ZIP
file](https://github.com/MillironX/beefblup/archive/v0.1.zip) and unzip it
someplace memorable
2. Make a copy of the "Master BLUP Worksheet" and replace the sample data with your own
3. If you wish to add more contemporary group traits to your analysis, replace
or add them to the right of the Purple section
4. Save and close
5. In your file explorer, copy the address of the "Julia" folder
6. Launch Julia
7. Type `cd("<the address copied in step 5")` and press **Enter** (For example,
`cd("C:\Users\MillironX\Documents\beefblup\Julia")`)
8. Type `include("beefblup.jl")` and press **Enter**
9. Select the spreadsheet you created in steps 1-4
10. Follow the on-screen prompts
11. **#KeepEPDsReal!**
1. Make a copy of the "sample.csv" spreadsheet and replace the data with your own
1. The trait you wish to calculate EBVs for always goes in the rightmost column
2. If you wish to add more contemporary group traits to your analysis, include them before the rightmost column
2. Save and close
3. In your file explorer, copy the address of the "beefblup" folder
4. Launch Julia
