# Manual installation

> **Note:** We recommend using Homebrew to install and update COSEDA. Instructions are available for [Linux/Windows](Install-on-Linux-Windows) and [MacOS](Install-on-MacOS). If you still choose to do a manual installation, the following instructions might be helpful.

If you haven't installed Conda on your machine yet, let's download the Miniconda installer first. Open a new Terminal and paste the following line:

```bash
curl -O https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
```

for Linux/WSL2 (x86) or

```bash
curl -O https://repo.anaconda.com/miniconda/Miniconda3-latest-MacOSX-arm64.sh
```
for MacOS (Apple Silicon)

..and run it. You will be asked to review the license (“Press ENTER to continue”, etc.):

```bash
bash Miniconda3-latest-Linux-x86_64.sh
```
or 
```bash
bash Miniconda3-latest-MacOSX-arm64.sh
```

> **Note:** On some systems you’ll need to `chmod +x Miniconda3-…sh` before running it. Usually you can skip this step.

After the installation is finished, initialize it:

```bash
"$HOME/miniconda3/bin/conda" init bash
```

For the changes to take effect, you now need to close your current shell and open a new one.

Now we can clone the repository:

```bash
git clone https://gitlab.com/kristallorakel/coseda.git
```

And move to the COSEDA directory:

```bash
cd coseda
```

There is already a YAML file in the Repository. Once you run the following line, Conda will create a new environment:

```bash
conda env create -f environment.yml
```

Once this is done, we can activate the environment and install COSEDA:

```bash
conda activate coseda && pip install -e .
```

Congrats, the installation is done. Now you can type "coseda", hit enter and a new COSEDA window should pop up!

> **Note:** After restarting your shell, you need to activate the environment again by `conda activate coseda`.

Some of the functions require a CrystFEL installation. You can find installation instructions [here](https://gitlab.desy.de/thomas.white/crystfel/-/blob/0.11.1/INSTALL.md).
