+## Custom Data Types
+You can register your own data types and also a custom section parser
+Access the ValueRegistry with:
+```java
+final ValueRegistry registry = ValueRegistry.REGISTRY;
+```
+After that, we can register a simple data type:
+```java
+registry.register(BigDecimal.class, InlineValue.<BigDecimal>builder()
+  .matches(text -> {
+    try {
+      new BigDecimal(text);
+      return true;
+    } catch (final Exception e) {
+      return false;
+    }
+  })
+  .deserialize(text -> {
+    if (!text.startsWith("bigDecimal(") && !text.endsWith(")")) return null;
+    return new BigDecimal(text.substring(11, text.length() - 1));
+  })
+  .serialize(bigDecimal -> "bigDecimal(" + bigDecimal.toString() + ")")
+  .build()
+);
+```
+You can also make a simple Ticket section or whatever if you like storing stuff without repeating code.
+```java
+public record Ticket(@NotNull UUID user, long date) {}
+
+registry.register(Ticket.class, InscriptValue.<Ticket>builder()
+  .serialize((ticket, section) -> {
+    section.set("user", ticket.user());
+    section.set("date", ticket.date());
+  })
+  .deserialize(section -> {
+    final Optional<UUID> user = section.get("user", UUID.class);
+    final Optional<Long> date = section.get("date", Long.class);
+
+    if (user.isEmpty() || date.isEmpty()) return null;
+    return new Ticket(user.get(), date.get());
+  })
+  .build()
+);
+```
+And we're done!
+---
+## Configuring the language
+If you want to change stuff like defining a list, or just want to change the indent, you can refer to the InscriptConstants interface.
+```java
+InscriptConstants.INDENT.set("  "::repeat);
+
+InscriptConstants.LIST_START.set("List(");
+InscriptConstants.LIST_END.set(")");
+```
+---
+## Using Inscript
+You can load/save contents from/to files, or just load/save contents from/to strings.
+If you want to use files, you have to provide a `Path` or a `File`.
+```java
+final Path path = Path.of(/* ... */);
+final Inscript inscript = Inscript.newInscript(path);
+```
+If you want to use the latter, you don't need to provide anything:
+```java
+final Inscript inscript = Inscript.emptyInscript();
+```
+
+To obtain the inscript editor, you use `Inscript.getEditor()`.
+
+Loading:
+1. Files
+   ```java
+   inscript.loadFromDisk();
+   ```
+2. String
+   ```java
+   inscript.loadFromString("gender = \"male\"")
+   ```
+
+Saving:
+1. Files
+   ```java
+   inscript.saveToDisk();
+   ```
+2. String
+   ```java
+   final String saved = inscript.saveToString()
+   ```
