+## Why
+
+I needed a library to store time-series data locally and the options out there didn't quite work for my case. Prometheus was too heavy for what I needed but I wanted that level of compression. tstorage was close but it didn't have the compression or label indexing.

+## Install

 ## Features
 
 - **Gorilla XOR compression** — ~1 byte/sample on regular metric data (see benchmarks below)
-- **Crash-safe** — WAL with CRC32C records; kill -9 at any point loses at most uncommitted samples
+- **Crash-safe** — WAL with CRC32C records. Committed data is persisted
 - **Query by label matchers** — equality, negation, regex, negative regex; merged across head and blocks
 - **Levelled compaction** — 2h → 8h → 32h blocks, background merging, retention-based expiry
 - **Self-instrumentation** — the DB records its own metrics (series/chunk counts, compactions, WAL fsync duration) through the normal write path, queryable like any other series
-- **Zero external dependencies** (except testify for tests)
+- **Zero external dependencies**

 [tstorage](https://github.com/nakabonne/tstorage) is the closest existing embedded TSDB for Go. It doesn't do Gorilla compression or label-based indexing, which is most of why ingot exists.

 ## Non-goals
 
 Replication, query languages, non-float64 values, deletes, multi-process access, out-of-order ingestion, Windows (sorry not my thing). Check DESIGN.md for reasoning.
