 ## Introduction
 
 Simple Object Storage is a very simple C++ webserver 
-which provide a store of binary objects (the objects can be large),
+which provides a store of tagged binary objects (the objects can be large),
 which are available over http.
 
 Read access is public.
 Write access is controlled by tokens.
 
+Public read actions:
+
 - Objects are access via a label and tag, or via their hash. For example:
    - `wget http://localhost:8123/object/squashkiwi:latest`
    - `wget http://localhost:8123/object/4528400792837739857`
-- The hash is calculated using `uint64_t hash_file(const std::string &path);` in hash.hpp.
-- You can retrieve the hash for a given labvel and tag with, e.g.:
+
+   - `curl http://loclahost:8123/exists/squashkiwi:latest`
+   - `curl http://localhost:8123/exists/4528400792837739857`
+
+- You can retrieve the hash for a given label and tag with, e.g.:
    - `curl http://localhost:8123/hash/squashkiwi:latest`
+
 - you can get a full list of {label:tag,hash} entries (one tag per entry) with:
    - `curl http://localhost:8123/dir`
+
 - get all metadata for a tag:
    - `curl http://localhost:8123/meta/squashkiwi:latest`
-- a simple welcome page is served at `/index.html` for those browsing to the site.
+
+
+Write actions:
+
 - to upload a file (via http put)
    - `curl -T object_file http://localhost:8123/upload?token="WRITE_TOKEN"\&labeltag="LABEL:TAG"\&filename="FILENAME"`
    - the object_file is uploaded, hashed, added to the registry (if that hash doesn't already exist), and {label:tag,hash} is added to the directory index.
+
 - to delete a label/tag (object remains):
    - `curl http://localhost:8123/deletetag?token="WRITE_TOKEN"\&labeltag="LABEL:TAG"`
+
 - to delete an object (and all tags on that object):
    - `curl http://localhost:8123/deleteobject?token="WRITE_TOKEN"\&hash="HASH"`
+
 - add a tag to an existing object:
    - `curl http://localhost:8123/appendtag?token="WRITE_TOKEN"\&hash="HASH"\&labeltag="LABEL:TAG"`
-- the server is configured via a configuration file which allows setting:
+
+- the server is configured via ~/.config/simple_object_storage/config.json which allows setting:
    - the list of write access tokens
    - the location for the object store (path on disk)
 
-The C++ program is written so that it only uses standard libraries, and is built as a static executable with musl not glibc.
 
-The C++ program is built with cmake.
-
-A Dockerfile is included for conveniently running the C++ program inside docker.
+Dockcross is used to cross-build for both 64-bit x86 and arm64 (combining both into one docker container image).
