+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# Terminus
+
+Terminus is a Scala 3 library for working with the terminal.
+It currently supports the JVM, via [JLine][jline]. 
+We intend to add [Scala Native][scala-native] and [Scala.js][scala-js] support .
+
+
+## Setup
+
+To use Terminus, add the following to your `build.sbt`
+
+```scala
+libraryDependencies += "org.creativescala" %% "terminus" % "@VERSION@"
+```
+
+
+## Usage
+
+Import Terminus
+
+```scala mdoc:silent
+import terminus.*
+```
+
+Now you can call methods on the `Terminal` object. The core methods are `read` and `write`, but there are also methods to change color, move the cursor, erase content, and so on. Don't forget to call `flush` or your output won't appear. Wrap a call to `run` around your entire program. Here's a small example that prints bright red text.
+
+
+```scala mdoc:silent
+Terminal.run {
+  Terminal.foreground.brightRed{
+    Terminal.write("This is Terminus!")
+    Terminal.flush()
+  }
+}
+```
+
+Here's a more involved example that demonstrates interactivity. It displays a prompt that asks the user to choose between three choices.
+
+```scala
+import terminus.*
+import terminus.effect.Eof
+
+enum KeyCode {
+  case Down
+  case Up
+  case Enter
+}
+
+def clear(): Program[Unit] = {
+  Terminal.erase.screen()
+  Terminal.cursor.to(1, 1)
+}
+
+def writeChoice(description: String, selected: Boolean): Program[Unit] =
+  if selected then Terminal.display.bold(Terminal.write(s"> ${description}\r\n"))
+  else Terminal.write(s"  ${description}\r\n")
+
+// Write the UI, with the currently selected option in inverse video
+def write(selected: Int): Program[Unit] = {
+  Terminal.write("How cool is this?\r\n")
+  writeChoice("Very cool", selected == 0)
+  writeChoice("Way cool", selected == 1)
+  writeChoice("So cool", selected == 2)
+  Terminal.flush()
+}
+
+def read(): Program[KeyCode] = {
+  Terminal.read() match {
+    case Eof =>
+      throw new Exception("Received an EOF")
+    case char: Char =>
+      char match {
+        case 10 | 13 => KeyCode.Enter
+        case '\u001b' =>
+          Terminal.read() match {
+            // Normal mode
+            case '[' =>
+              Terminal.read() match {
+                case 'A'   => KeyCode.Up
+                case 'B'   => KeyCode.Down
+                case other => read()
+              }
+
+            // Application mode
+            case 'O' =>
+              Terminal.read() match {
+                case 'A'   => KeyCode.Up
+                case 'B'   => KeyCode.Down
+                case other => read()
+              }
+
+            case other => read()
+          }
+        case other => read()
+      }
+  }
+}
+
+def loop(idx: Int): Program[Int] = {
+  write(idx)
+  read() match {
+    case KeyCode.Up =>
+      clear()
+      loop(
+        if idx == 0 then 2
+        else idx - 1
+      )
+
+    case KeyCode.Down =>
+      clear()
+      loop(
+        if idx == 2 then 0
+        else idx + 1
+      )
+
+    case KeyCode.Enter => idx
+  }
+}
+
+@main def prompt(): Unit = {
+  val idx =
+    Terminal.run(
+      Terminal.raw { loop(0) }
+    )
+
+  println(s"Selected $idx")
+}
+ 
+```
+
+
+## Design
+
+The API in the `terminus` package provides a functional API for working with the terminal.
+Methods consume and return context functions with type
+
+```scala
+type Program[A] = Terminal ?=> A
+```
+
+where `Terminal` is a backend specific implementation that handles interfacing with the terminal. A `Program` represents a function that, when run, will do something with the terminal.
+
+Context functions are new to Scala 3, so many developers may not be familiar with how they work. There are three rules for working with them:
+
+1. If the compiler can tell that a context function is expected it will automatically create one. We can do this putting a `Program` type annotation. Here are some examples
+
+  ```scala
+  // Most of the methods on Terminal return programs
+  val aTerminalOperation: Program[Unit] = Terminal.write("Some text")
+
+  // Any expression can be a Program with a type annotation
+  val aProgram: Program[Int] = 1 + 1
+ ```
+
+2. If there is a `given` value of the appropriate type in scope, any context functions will be automatically applied to that `given`. This is what allows us to write effectful code in so-called *direct-style*, which just means writing normal code without monads or other complications. Here's an example that mixes effectful code, using the terminal, with some normal code. Notice that the entire result is a `Program`. This type annotation means the compiler constructs a context function around the entire block.
+
+  ```scala
+  val writeSomeStuff: Program[Unit] = {
+    Terminal.write("Some output")
+    // We can mix normal code in
+    1 + 1
+    Terminal.write("More output")
+    Terminal.flush()
+  }
+  ```
+  
+  We can do the same thing with a method, by specifying the return type is a `Program`. Here's an example.
+  
+  ```scala
+  def doSomeStuff(): Program[Unit] = {
+    Terminal.write("Some output")
+    1 + 1
+    Terminal.write("More output")
+    Terminal.flush()
+  }
+  ```
+
+3. If we don't tell the compiler we're expecting a context function, we may get an error when the compiler attempts to apply a context function to a given value that does not exist.
+
+  ```scala mdoc:fail
+  Terminal.write("Some output")
+  ```
+
+If you want to work directly with the terminal, without working with context functions, you can work with the types in `terminus.effect`.
+
+
+## Notes
+
+You won't be able to run terminal programs from sbt if the JVM forks when running. That is, if you have the setting
+
+```scala
+run / fork := true
+```
+
+the forked JVM won't have access to a terminal and therefore any terminal programs will not work as expected.
