+# PurePkg
+
+Simple C package manager.
+
+## Planned features
+
+The package manager itself should be a simple bash script and it will use
+a few dependencies like `jq` to make it easier to implement.
+
+- fetching dependencies
+- adding new dependencies
+- removing dependencies
+- updating dependencies = remove + add + fetch
+
+The package manager will guarantee transaction nature of these operations.
+
+### Files structure
+
+The idea is for the package manager to use the following files:
+
+- `purepkg-deps.json` -- user-defined dependencies, may be added by hand
+  or by using ./purepkg.sh add command
+- `purepkg-lock.json` -- stores information about installed packages,
+  their versions, names, descriptions, licenses
+- `purepkg-this.json` -- contains information about the current repository
+  being a package. It defines name, description, license and a list of
+  paths to files, which should be fetched by someone adding this as a
+  dependency
+- `.purepkg/` -- directory for storing intermediary results of operations,
+  before everything succeeds no other file is touched by this manager
+- `purepkgs/` -- directory where packages files are placed. Currently the
+  idea is that the user will use them from this place to include or link
+  -- which may involve creating symlinks to the files to place them in
+  project-specific directories. It is some plan for future to add
+  symlinks creation automatically, but this needs to be revised
