+# Installing the library
+
+TODO: add support to content tabs
+
+=== "Rust"
+
+Add the `nostr` dependency in your `Cargo.toml` file:
+
+```toml
+[dependencies]
+nostr = "0.24"
+```
+
+Alternatively, you can add it directly from `git` source:
+
+```toml
+[dependencies]
+nostr = { git = "https://github.com/rust-nostr/nostr", tag = "v0.24.0" }
+```
+
+```admonish note
+To use a specific commit, use `rev` instead of `tag`.
+```
+
+=== "Python"
+
+The `nostr-protocol` package is available on the public PyPI:
+
+```bash
+pip install nostr-protocol 
+```
+
+=== "Kotlin"
+
+To use the Kotlin language bindings for `nostr` in your Android project add the following to your gradle dependencies:
+
+```kotlin
+repositories {
+    mavenCentral()
+}
+
+dependencies { 
+    implementation("io.github.rust-nostr:nostr:<version>")
+}
+```
+
+## Known issues
+
+### JNA dependency
+
+Depending on the JVM version you use, you might not have the JNA dependency on your classpath. The exception thrown will be
+
+```bash
+class file for com.sun.jna.Pointer not found
+```
+
+The solution is to add JNA as a dependency like so:
+
+```kotlin
+dependencies {
+    // ...
+    implementation("net.java.dev.jna:jna:5.12.1")
+}
+```
+
+=== "Swift"
+
+### Xcode
+
+Via `File > Add Packages...`, add
+
+```
+https://github.com/rust-nostr/nostr-swift.git
+```
+
+as a package dependency in Xcode.
+
+### Swift Package
+
+Add the following to the dependencies array in your `Package.swift`:
+
+``` swift
+.package(url: "https://github.com/rust-nostr/nostr-swift.git", from: "0.0.4"),
+```
+
+=== "JavaScript"
+
+```bash
+npm i @rust-nostr/nostr
+```
