How to add a new language to your ABP project?

Adding a new language to your ABP project is pretty simple. Let's add the German language to our ABP project:

Go to your solution's root folder and write the following CLI command. This command will generate an empty translation file from English.
```
abp translate -c de-DE
```
Check out for the complete supported culture codes. (For internal development D:\Github\abp and D:\Github\volo\abp)
Fill the target fields in your target language.
Copy abp-translation.json your solution's root folder (Do not change the filename!)
Run the following command. This command will create the necessary json files.
```
abp translate --apply
```
Open your solution and add the new language to the language list. To do this;
- open MyProjectNameDomainModule.cs and in ConfigureServices you'll find Configure<AbpLocalizationOptions>. If you have HttpApi.Host project then you need to add this in MyProjectNameHttpApiHostModule.cs
```
options.Languages.Add(new LanguageInfo("de-DE", "de-DE", "Deutsch", "de"));
```
The last parameter is the flag icon. You can find the list of flag icons on https://flagicons.lipis.dev/
The last step is running the DbMigrator project. It will seed the database for the new language.

Close the IIS Express / Kestrel to invalidate the language cache and run the project. You will see the new language on your website.
