+# Install requirements
+
+There are two ways to install the requirements. One is to install the primary dependency
+`tmtccmd` interactively. This is the recommended way
+
+Assuming you are running in a virtual environment:
+
+1. Install `tmtccmd` for virtual environment. `-e` for interactive installation.
+
+   ```sh
+   cd tmtccmd
+   pip install -e .[gui]
+   ```
+
+2. You can also install the `spacepackets` package locally/interactively
+   Normally, it will be installed as a `tmtccmd` dependency.
+
+   ```sh
+   cd spacepackets
+   pip install -e .
+   ```
+
+Alternatively you can also install the packages from PyPI completely, but the risk of
+incompatibilities will be high there
+
+```sh
+pip install -r requirements.txt
+```
