+## More detailed explanation
+
+1. Install dotnet-ef, and include it in your $PATH if necessary:
+
+    ```
+    dotnet tool install --global dotnet-ef
+    export PATH="$HOME/.dotnet/tools:$PATH"
+    ```
+
+1. In `src/Ombi`, install the `Microsoft.EntityFrameworkCore.Design` package:
+
+    ```
+    cd src/Ombi
+    dotnet add package Microsoft.EntityFrameworkCore.Design
+    ```
+
+1. For some reason, the `StartupSingleton.Instance.SecurityKey` in `src/Ombi/Extensions/StartupExtensions.cs` is invalid when running `otnet ef migrations add` so we must fix it; apply this patch which seems to do the job:
+
+    ```

+1. List the available `dbcontext`s, and select the one that matches the database your fields will go in:
+
+    ```
+    cd src/Ombi.Store
+    dotnet ef dbcontext list
+    ```
+
+1. Run the migration using the command at the start of this document: 
+
+    ```
+    cd src/Ombi.Store
+    dotnet ef migrations add <name> --context <context> --startup-project ../Ombi/Ombi.csproj
