+## Semaphore
+
+Naive resource management / concurrency primitive
+
+`npm i @calebboyd/semaphore`
+
+### Example
+```javascript
+import { Semaphore } from '@calebboyd/semaphore'
+import { something } from './somewhere'
+
+function doSomeWork () {
+  const lock = new Semaphore(10)
+  while(something.isTrue) {
+    lock.acquire().then(x => () => {
+      something.work().then(lock.release)
+    })    
+  }
+}
+```
+The semaphore will only allow 10 locks to be aquired at a time. This limits the concurrency of the asyncronous function `something.work` to 10
+
+#### API: 
+
+```typescript
+export class Semaphore {
+  constructor (count: number) {}
+  acquire(): Promise<void>
+  release(): void
+}
+```
