After **creating a Custom Library**, the library starts empty, so you need to add simulations before learners can access the content you want them to use. In SimFlow, each simulation is built around a **Character** - this helps keep each library focused on the right simulations for its intended learners.

**Info:** SimFlow uses two related terms. A **simulation** is the overall exercise a learner runs - the conversation itself. A **Character** is the specific case or scenario within that simulation (who the learner is talking to, and why). When you're adding content to a library, you're selecting Characters, each Character represents one simulation a learner can run.

Let’s get started 🚀
## Find a Simulation to Add
After you create a library, SimFlow takes you directly to **Manage Characters**, where you can find simulations available to add. Use the search field or available filters to find the Character you want to add.
Use the interactive walkthrough below to find a Character to add to your library.

## Add the Simulation to the Library
Once you find the right Character, select **Add** to include it in the library. This makes the simulation available to learners through the library.
Use the interactive walkthrough below to add a Character to your library.
